9 Best AR-10 Rifle Builds

1. Brownells BRN-10

ar 10 for hunting

This rifle is a conventional AR platform design in that it mounts the H-bar carry handle and rear sight housing as well. It is the gold standard in ARs and was used throughout the Vietnam War as an AR-15 .223/556 NATO battle rifle, but in a smaller receiver platform.

Brownells offers this original Stoner-designed rifle, which was accepted world-wide as the up-gunned AR-10 and was built before the development of the AR-15. The changes are by way of advanced metallurgy techniques as in a fully forged and machined receiver.

The original rifles made use of a case receiver, which was one step above a stamp sheet metal configuration.

This rifle is chambered in 7.62 NATO/308 Winchester, in keeping with the original ammo specs assigned to the original rifle design. In other words, it is of a classic design but built of 21st-century materials as well as with CNC space age machining.

Material used in the receiver building process is a 7075 T6 aluminum billet. Only the best will do in this case, one could say.

The rifle's design carries the pedigree of the Armalite rifles that were built for combat originally for the US Government. The design development as applied to this rifle includes the original slab side lower receiver, with a straight magazine well, take down pins, and conventionally placed and reproduced controls.

This rifle does not retain the cartridge assist, or the shell deflector. This is in keeping with the classic look of the rifle. If you are interested in this rifle, remember that the firearm is a throwback to the original design of the AR platform. It is not intended to hold added gadgets and has no rails for tack-on tools, etc.

2. Daniel Defense DD5V4

ar-10 rifle

This rifle comes in both the 7.62X51mm and the new 6.5 Creedmoor. It is offered with a user-adjustable gas block that makes the weapon workable with custom loads as well as standard factory ammunition. Pick your gas pressure and start shooting.

This rifle has a DLC-coated bolt-carrier group that allows for easy cleaning, even when the rifle is undergoing hard use. The bolt itself is designed with an enhanced extractor geometry and retains a set of duel ejectors.

The barrel is an 18” cold-forged proprietary steel chrome-lined pipe, and the rifle uses the Daniel Defense 4-bolt lock connection system, which allows for greater accuracy.

The lower receiver on this rifle is enhanced, carrying the flared magazine well, and rear receiver QD swivel attachment point. It is CNC-machined of 7075 T6 aluminum, and is hard-coated with a Type III surface treatment.

The upper receiver on this rifle is CNC-machined and also Type III hard-coated for exterior strength in order to fight of excessive wear in the field. The trigger on this rifle is designed by the manufacture as a mil-spec system.

The handguard on the rifle is the Daniel Defense DD% rail 15.0 CNC-machined. It is made from 6061 aluminum and carries the M-Lok attachment design system.

You will find that this company offers a number of design options in AR-10 pattern rifles, and checking though the listings is a good idea as design elements change with each model. Some are fit for one service while others another.

I regard these rifles as current production designs within the industry, and clearly mission-capable as full service weapons with both police and military applications.

3. Palmetto Arms G-3

best 308 ar 10

Here is a company that is right on my current dealer listing. The folks at Palmetto Arms build rifles for themselves to sell and for a number of other companies as well. When these folks get over-run upper or lowers, the gloves come off and the roof falls into the basement regarding price.

I dearly love these guys and I have built rifles costing upwards of $1,880.00 for about a quarter of that price by buying parts for a new rifle-build from Palmetto.

Over-runs come along often as applied to production orders by brand X, Y or Z, and the best way to stay in touch with this element of the company is to watch out for deals on the net.

The PSA Gen 3 rifle is available in 6.5 Creedmoor and 308 Win (7.62X51 NATO). This AR-10 retains a 20” button-cut rifled barrel made of 416R stainless steel.

6.5 creedmoor ar-10

I shoot these barrels a great deal in conjunction with a company called Backridge Ammunition of Tennessee as a consultant, and we have found these rifles to be very accurate and all shoot within the sub MOA range of performance.

The profile on this barrel is heavy, meaning it can take heat and stay accurate even under semi-automatic sustained fire.

In the Creedmoor chambering the barrel retains a 1.8” twist. The gas operation system is full-length, and the gas block is a low profile 5-position click-switch adjustable block.

The upper receiver is forged and milled 7075 T6 aluminum, and the receiver is a flat top with feed ramps. The receiver finish is hard-coated anodized treated, and the system makes use of a full forward assist and dust cover.

The handguard on the rifle of a PSA 15 M-Lok has a free-floated rail with anti-slip anti-rotation features.

6.5 creedmoor ar-10

Fire control is by a two-stage nickel boron trigger, and the buffer tube system is of a 7075 T6 aluminum design. The grip on this rifle is a PSA over-molded A2 grip design, and the stock itself is Magpul STR based in black.

Magazine capacity 20 rounds. (Others available through PSA parts service).

These rifles can also be built from what I like to call stacking parts together. I own two of them that I built from parts obtained from the manufacture. You can build a complete Palmetto rifle from parts or as in the box rifle.

Parts rifles can cut costs by about 50% or more compared to a fully built over-the-counter rifle, depending on the specific build selected.

Being very specific regarding PSA uppers, as this is a trademark of the company, when building a complete rifle, some uppers change with availability, and at times you need to wait out the production runs for a given chamber size in an AR-10.

Selecting the PSA Geb 3 PA65 20” rifle length 6.5 Creedmoor, we will take a quick look at exactly what you're getting for your dollar.

This upper makes use of a rifle-length gas operation system, and the barrel is heavy in terms of both weight and construction. The barrel is built from 416 R stainless steel, and the muzzle is threaded at 5/8-24. An adaptor can be installed for the use of a suppressor.

Creedmoor twist rate is 1:8, and the barrel extension is an M-4 pattern. The diameter of the gas block is .750. and the gas operation system is a low profile 5-position click-adjustable block.

The gas top itself is black nitride finished, and the receiver material is forged 7075 T6, receiver-type PA10.

6. Magpul SL-S Stock AR-15/10

308 ar build

These stocks have been standard among both custom builders and over-the-counter factory-built ARs for years. They mount on mil-spec-size carbines and AR-10 platforms as well. The stocks retain two battery storage compartments.

The stock is designed with a sloping cheek weld, but still makes use of a slimline profile. Duel side release latches provide easy access to adjustments while still remaining snag-proof.

Lock springs on the stock are made of chrome silicon and provide a solid lock. This is important in the heavy calibers regarding recoil. I had a lock fail once on the 4-position stock and ended up requiring stitches on my nose and around my eye.

The stock makes use of an anti-rattle leaf-spring that reduces wobble on the receiver extension tube. The Rubber recoil pad provides a solid grip face against the shooter's shoulder, and the rollover style stock toe provides easy shoulder transition and a better fit when shooting.

7. Aero Precision M5E1 Complete Rifle

Aero Precision builds AR platforms one at a time using skilled gunsmiths who hand-fit the rifles during the builds. The complete rifle makes use of the very same high-quality parts that can also be obtained individually from this company.

The M5E1 is built using the mid-length barrel mated to the enhanced upper receiver. This makes use of a handguard and upper components that are lightweight and strong and that free-float the barrel itself for accuracy.

The barrel is made from 416R stainless steel with a 1:10 twist (308) and is bead-blasted in terms of a surface finishing approach.

Muzzle retains the standard AR-10 308-matched birdcage. This rifle is comparable regarding suppressor installation using the addition of a threaded adaptor.

8. Wilson Combat Recon Tactical

best ar 10 for the money

I use The Wilson Recon Tactical rifle as a base-line in terms of what Wilson puts into the rifle. This company with a simple e-mail order can build any one of a vast number of offerings including 308 7.62X51 NATO, and other rounds too numerous to cover here by using that base-line 308 mother case.

For the most part the Recon Tactical makes use of the short AR-15 cartridges, and that includes just about anything you can think of that will fit the receiver platform of this model.

Custom builds around this design will take about two weeks according to the manufacture. Any errors in the order made by the customer as in issue with local or state laws require a 10% re-stocking fee if the weapon is returned.

Wilson's rifles all retain very high-quality match-grade barrels, advanced gas systems, custom gas systems, and threaded muzzles with Q comp flash hides. The rifle uses M2 2-stage triggers, mil-spec bolt-carrier groups and are gunsmith-installed and inspected as an individual rifle versus assembly line mass-production.

M-Lok rail systems, gunfighter grips, and 2-stage triggers also make up some of the custom builds offered by Wilson. This is not a mass-production company to be sure.

The manufacturer will build exactly to your requirements, and that includes high-intensity cartridge applications like the .224 Valkyrie, 300 Blackout, 308 Win, 243 Win, and a total of 24 different chambering and configurations in this rifle. Can’t find it? Then it does not exist, save for some wildcat garage-build.

9. DPMS Panther Oracle 20+1 7.62X51 NATO

dpms ar 10 review

This rifle from DPMS is a heavyweight up-gunned AR that is chambered in the NATO 7.62 round. It is military to the core and a great weapon used by police and paramilitary individual operators.

Features on this rifle include a 16-inch M-4-style carbine barrel made from 4140 chrome moly steel. The barrel is equipped with anA2 flash hider, and is capable of mounting a suppressor by way of a transition kit. Barrel rate of twist is 1:10 standard, with the 308 Winchester cartridge.

The upper on this carbine retains the A3 style flat-top with an added Weaver-style accessory point located over the gas block. The flat receiver rail top allows fast installation of scopes, red dots and other methods of controlling rounds down-range.

The lower receiver is built from a billet of hard anodized aluminum, The fore-end on the rifle has military-styled glacier guards.

This is a great entry level rifle or, for that matter, a do-it-all workhorse for the shooter who wants an AR rifle design but is not very pleased at dropping a grand or more when getting into the AR-10 platform.

A final word on rifle builds

When turning to building your own AR-15 or AR-10 rifle, there are some considerations to bear in mind.

The best build for an investment and a solid return is the parts set obtained through a sold brand name versus some no name outfit on the internet. In truth, sellers have a hard time pricing a build at times because of the range of brands or, at times, no brand name associated with the build.

As a licensed federal dealer, seller, and even manufacturer myself (Metrogun TM), I can attest to this situation becoming a problem at times. The solution is stay with named brand parts. Stay with complete custom builds offered by top-of-the line brands, or get your parts as a total kit through a brand name company.

In the end, you will gain rather than lose when it is time to turn the firearm over for another model. I have never had any trouble turning over complete builds when some of the brands listed here were used.
