The PSA Sabre AR-10 is a rifle that’s constructed within the model of designated marksman rifles just like the Knight’s Armament M110. AR-10s have been round even longer than AR-15s, however in fashionable type, they goal to seize the advantages of a semi-auto fuel gun whereas offering good accuracy and higher long-range authority than these chambered in .223 Rem. or 5.56mm NATO. As with a lot of their different weapons, Palmetto State Armory affords their model at a fraction of the worth of many high-end AR-10s.
From the time I used to be ordering AR elements kits from Shotgun Information, I’ve celebrated a cut price. However I’ve additionally realized to query them. With any kind of rifle, you normally get what you pay for. However that doesn’t imply that reasonably priced rifles are junk — not less than not all of them. I take pleasure in a particular satisfaction when discovering weapons which might be each reasonably priced and carry out effectively, however I don’t lower them any slack. I’ve put over 600 rounds via a PSA Sabre 10 of my very own previously couple months — usually in sub-zero temperatures — right here’s what I believe.

The PSA Sabre 10: An Reasonably priced AR-10
There are many AR-10 rifles available on the market, a lot of which solely have trivial variations. LIke the AR-15, the AR-10 is a machinists gun. The place it lacks the expert craftsmanship {that a} hand-bedded, finely-tuned M1A or conventional bolt motion has, it makes up for with standardization and interchangeability of elements. AR rifles are comparatively straightforward to assemble and parts are easy to swap. This makes it a lovely platform for tinkerers and simple to keep up for on a regular basis shooters. The common nature of those rifles additionally blurs the strains of notion between what you is perhaps getting with an costly rifle just like the Seekins SP10 and what you may count on from a extra reasonably priced one just like the PSA Sabre 10. The identical goes for elements and uppers/lowers.
The distinction in reasonably priced ARs and costly ones is within the particulars. Sure, they’re comparable. No, they don’t seem to be the identical factor. The parts and on-range efficiency and reliability with onerous use is the place you’ll see the distinction. With that in thoughts, let’s stroll via the PSA Sabre 10. This rifle is accessible in each 6.5 Creedmoor and .308, and in quite a lot of configurations.
Receivers and Furnishings
The PSA Sabre that I examined has a cast higher receiver and a primary Sabre decrease receiver. There isn’t any fancy machining, no decorative bevels or texturing, and the set off guard is mounted. The entire decrease has a black Cerakote end and features a Magpul grip. The higher receiver is cast in a equally primary model with an integral Picatinny rail on prime. The match is a bit of free between the higher and decrease receiver — a quite common, inconsequential factor with AR rifles. The PSA Sabre 10 decrease receiver doesn’t have a tensioning screw that some AR lowers do, however the wobble you are feeling doesn’t ever appear to have an effect on accuracy. In order for you an ultra-tight match you will get an accuwedge or, as I did, merely add a bit {of electrical} tape to the highest of the decrease receiver on either side, simply above or ahead of the rear takedown pin. The tape acts as a shim and eliminates play between the receivers.
The handguard is a free float tube that clamps onto the barrel nut and has tabs on both aspect of the highest of the receiver to forestall rotation. The octagonal handguard has knurled texturing on the aspect panels and slanted texturing on the 2-, 4-, 8-, and 10-o’clock sides. The rail has M-Lok slots at 12-, 3-, 6-, and 9-o’clock, and the highest has a piece of Picatinny rail on the entrance and rear. The handguard is helpful for attaching equipment, and has a QD sling cup on both aspect. It isn’t too cumbersome, and is simple to get a support-hand wrap on for quick, modern-style, up-close capturing.
The rifle has a carbine-length buffer tube with a Magpul PRS Lite stock. This inventory supplies an adjustable match for precision capturing, however isn’t cumbersome, and is half the worth of the common Magpul PRS stock.
Inside Elements and Gasoline System
The PSA Sabre AR-10 makes use of Palmetto’s two-stage set off that’s held in place by anti-walk pins. It’s a bit of mild for a rifle of this model. Regulation weight for a contest service rifle is 4 kilos, 8 ounces. The PSA Sabre set off measured 2 kilos 7 ounces on my Lyman set off pull scale, but it surely has a very good steadiness between the primary and second levels. The primary stage is roughly 14 ounces, and a further 1 pound, 9 ounces must be added to interrupt via the second. Although I’d reasonably see it nearer to three or 4 kilos, it’s an efficient center floor between offering a fragile, precision-capable set off, and one that may be fired easily in a fast cadence.
The bolt service group is chrome-plated, which makes cleansing a bit simpler, and the recoil lugs have some slight beveling—one thing that ought to assist them last more when subjected to heavier .308 and 6.5 Creedmoor fireplace and fixed interplay with the barrel extension. The extractor makes use of a stout double spring, and the twin ejectors are stiff, and pop spent circumstances from the receiver effortlessly. The fuel rings have a pleasant tight match with the bolt service. The rifle makes use of a Radian Raptor LT charging deal with and Radian Talon ambidextrous security selector.
On the rear, the rifle has a Palmetto round-coil buffer spring and comes with an H buffer. Up entrance, it has a mid-length fuel tube with an adjustable fuel block — extra on this in a minute. Usually, the rifle has all good-quality parts, however they’re pretty pedestrian.
Capturing the PSA Sabre 10
Capturing the PSA Sabre has been each fulfilling and academic. Don’t fear, that doesn’t imply something too dangerous, it simply implies that I’m nonetheless a sluggish learner. Although I’ve fired hundreds upon hundreds of rounds via AR-15 rifles, my expertise with the AR-10 platform is extra restricted. My two largest questions concerning the PSA had been how correct wouldn’t it be, and the way dependable?
The Significance of Tuning the PSA Sabre 10 Gasoline System
The rifle got here with a information for tuning the fuel system, with the adjustable fuel block set on the factory-recommended setting. A fuel block is part that slips over the barrel to direct fuel up from the fuel port drilled into the barrel, and again via the fuel tube to cycle the motion. An adjustable fuel block of this model has a set screw that may be screwed in or out to manage the circulate of fuel again into the receiver. This fuel adjustment screw is down underneath the handguard, and the rifle comes with a protracted Allen key for turning it. On my first journey to the vary, I left it on the manufacturing unit setting. The rifle cycled effectively, so I left it alone — one thing the common shooter will do.
For the subsequent journey, I eliminated the three-prong flash hider/compensator, and threaded on a Silencer Central Banish Backcountry titanium suppressor. For any rifle work that doesn’t contain full-auto fireplace or relentless magazine dumping, this is a wonderful can for this rifle. It’s mild, quick, and unobtrusive. The truth is, with this shorter 18-inch barrel, it doesn’t actually change the dealing with traits of the rifle in any respect. I can’t say that for the strong stainless suppressor I placed on the 20-inch barrel of my first DPMS AR-10 a few years in the past.
Overgassing the PSA Sabre 10 Will Break Stuff
I started capturing and accumulating accuracy knowledge utilizing this suppressor and a Silencerco Omega 36m, a heavier modular can. I didn’t pay a lot consideration and the rifle cycled fantastic, till it began ripping off two or three rounds per set off pull. I ought to have identified the difficulty instantly, however like I mentioned, I’m sluggish. I used to be considering that when resting on luggage, the recoil was resetting the set off and successfully bump-shooting the rifle. Finally, my bolt catch broke — no sweat, that’s straightforward to interchange — and after I tore the gun down to examine it extra carefully, I observed that I had smashed the buffer to hell. I had been working the rifle approach over-gassed and the gun was typically out-running the disconnector. I knew that placing a suppressor on an AR or different gas-driven rifle will enhance the fuel strain, I incorrectly assumed it wouldn’t be that delicate.
The PSA Sabre 10 in 6.5 Creedmoor comes with an H buffer. I occurred to solely have a spare H3 buffer, which is heavier, so I put in that one. I turned the fuel all the way in which down and slowly opened it till the gun would cycle reliably. This gave me a sluggish chachunk biking pace, and ultra-soft recoil. I swapped forwards and backwards between suppressed and unsuppressed with quite a lot of ammo and my takeaway is that you might want to tune the fuel for every particular person load and any time you’re taking off or placed on a suppressor. If the gun is biking completely with a can, it in all probability gained’t run with out the can till you open up the fuel by a setting or two. If the rifle is ejecting brass ahead, between 1-o’clock and 3-o’clock, you’re overgassed. Dial it down.
Gasoline System Lengths in AR-10 Rifles
I’ve famous that lots of the extra refined, and costly, rifles have rifle-length (or longer) fuel programs. The Seekins SP10, for instance, employs this longer fuel system with a heavy bolt service group and flat-coil recoil spring for easy and dependable operation. It’s straightforward to get away with quite a lot of fuel tube lengths with 5.56-class cartridges, however the .308 and 6.5 Creedmoor generate way more fuel. I don’t suppose that the shorter fuel system is as forgiving, and that’s an enormous distinction between this and among the rifles that price two or thrice as a lot.
Finally I discovered the PSA Sabre 10 to be fairly dependable, but it surely does require cautious consideration to how the fuel system is tuned. All of my capturing was performed between minus 10 levels and plus 35 levels, and the gun ran effectively. Along with capturing over 200 rounds accumulating accuracy knowledge, I spent a number of time capturing at metal out to 350 yards and firing full magazines via the gun shortly to see how it might run. Like most ARs, it slows down a bit when it will get soiled, and opening the fuel briefly helps with that. As a result of it does require some adjustment, I believe it’s sensible to periodically rotate the fuel adjustment screw via its whole vary to forestall carbon construct up and corrosion from seizing it.
How Correct is the PSA Sabre 10 in 6.5 Creedmoor?
I’m all the time a bit of nervous testing rifles and pistols on the decrease finish of the worth spectrum as a result of in the event that they shoot like I hope they are going to, they’re a fantastic cut price. A few of them are only a turd sandwich. One level upon which I’m joyful to brag on the PSA Sabre 10 is its precision. I shot the hell out of this gun, and the bead-blasted stainless barrel exceeded my expectations for a fuel gun like this. I recorded 41 5-shot teams with 9 completely different hundreds (6 manufacturing unit hundreds and three hand hundreds). For an accuracy common, I lower the underside 10 % of teams to get rid of error from fouling photographs or human enter. One of the best 37 teams averaged underneath an inch at .952 inches. If we common the very best 10 teams I recorded, a protocol we’ve got lengthy used for our accuracy figures, we get a mean of .689 inches. That’s solely barely bested by the Seekins SP10 that Snow examined (.650 inches).
The rifle preferred quite a lot of manufacturing unit ammo, like Hornady Precision Hunter 143-grain ELD-X (common: .881 inches), and shot Palmetto State’s AAC 140-grain Sabre Blade ammo effectively too (common: 1.600 inches). General, the rifle appeared to favor the Hornady 143-grain ELD-X bullet. I attempted two manufacturing unit hundreds and two hand hundreds with that bullet — all 22 5-shot teams mixed averaged .892 inches.
20-Shot Teams
At OL, we’re all the time striving to enhance our testing — typically to a fault, and that goes for accuracy knowledge too. We’ve by no means collected as a lot knowledge on every gun as we do now (nobody else does both), and that permits us to current much more legitimate, related accuracy numbers. We’ve leaned on 5-shot groups over 3-shot groups for years, and though a big quantity of 5-shot teams provides us a dependable common, the variability from group to group can nonetheless be frustratingly giant. Any given 5-shot group has a very good likelihood to be bigger than the general common.
A 20- or 30-shot group is a way more dependable determine, and nearly any 3- or 5-shot group you fireplace will fall inside the 20-shot dispersion boundary. Utilizing group evaluation software program, we’re in a position to plot every shot from a number of 5-shot teams to provide us an combination group dimension. One other good thing about a 20-shot group is that we will calculate a sound imply radius. That is the common distance between every shot and the true zero of the group. If a shot has a radius of .25 inches, that implies that the shot impacted .25 inches from the true zero level. Imply (common) radius is solely the common distance by which your photographs miss the true zero. The place the general group dimension solely tells you ways far aside your worst two photographs had been, imply radius tells you ways shut zero your common shot in a variety falls.
How does that search for the PSA Sabre 10? Fairly rattling good. With Hornady Precision Hunter 143-grain ELD-X, the PSA Sabre had a 20-shot group dimension of 1.13 inches and a imply radius of .337 inches. Capturing an outdated hand load utilizing Hornady Superformance powder and 143-grain ELD-X bullets, it had a 20-shot group dimension of 1.245 inches with a imply radius of .411 inches. I’ve shot a number of bolt-action searching rifles that wouldn’t common that with 5-shot teams. It’s stellar.
What the PSA Sabre 10 in 6.5 Creedmoor Does Properly
I believe that this rifle is a superb worth. It’s exceptionally correct for a fuel gun in its value vary, has good elements, and is a wonderful purchase for an entry-level AR-10 that may carry out. It has a very good set off, good hand guard, and the PRS Lite inventory is a superb contact.
The place the PSA Sabre 10 in 6.5 Creedmoor Might Be Higher
My solely bother with the PSA Sabre 10 was partly my very own negligence. Although I did discover the rifle to be completely dependable when rigorously tuned for a given load, I don’t suppose the mid-length fuel system is as forgiving as an extended one may very well be. A shooter who isn’t paying consideration is prone to tear the gun up or encounter reliability points.
