Description
There are plenty of AR-10s out there that feel like an afterthought next to a company's AR-15 lineup. The UIC10A is not one of them. American Defense Mfg built this .308 from the ground up on SR-25 pattern receivers machined from aircraft-grade billet aluminum, then carried over the patented fully ambidextrous controls from their UIC-15 rifles. Bolt release, safety, mag release, all of it works from either side, and the Raptor ambidextrous charging handle keeps that theme going up top. Left-handed shooters get a rifle that finally works with them instead of against them, and righties get faster manipulations too.
A Criterion Barrel Does the Heavy Lifting
The 16-inch Criterion match-grade barrel is the heart of this rifle. It's 416R stainless steel with a nitride finish, cut with a 1:10 twist and an M118 chamber, which means it digs into heavier match loads like 175 grain ammo without complaint. Feeding it is a .308 enhanced bolt carrier group running on a rifle-length gas system, a smart choice on a 16-inch gun that noticeably softens the recoil impulse of a big-bore semi-auto. The SLR Sentry 7 adjustable gas block lets you dial the system in for your ammo, or turn it down when you add a can.
Built for the Suppressor Crowd
That HUXWRX muzzle device on the end is more than a flash hider. It's the quick-detach mount for HUXWRX flow-through suppressors, so if you're already in that ecosystem or planning to be, this rifle attaches your can in seconds with no extra parts to buy. The 15-inch M-LOK handguard gives you plenty of room for a bipod, light, or hand stop, and the Magpul SL stock keeps things sturdy in the shoulder.
Where the UIC10A Earns Its Keep
At around 9.4 pounds unloaded, this is a designated marksman style rifle that shoots like it, with owners reporting tight groups at 100 yards and solid performance in long-range classes. It ships with one 30-round magazine, wears a hard-coat Type III anodized black finish, and is made in the USA by the same Wisconsin crew known for their bomb-proof optic mounts.

Frequently Asked Questions
Will the UIC10A work with my HUXWRX suppressor?
Yes, that's the whole point of this particular configuration. The factory-installed HUXWRX muzzle device doubles as the quick-detach mount for HUXWRX flow-through suppressors, so your can locks on in seconds with no additional hardware. If you run a different suppressor brand, the muzzle device can be swapped like any other threaded device.
How accurate is the American Defense UIC10A in .308?
The Criterion match-grade barrel is the star here, and Criterion has a strong reputation among precision AR builders. The 1:10 twist and M118 chamber are set up to shine with heavier match loads in the 168 to 175 grain range. Owners have reported near-touching groups at 100 yards, which is excellent for a semi-auto .308 carbine.
Are the controls on the UIC10A really fully ambidextrous?
They are. American Defense's patented ambi control setup carries over from their UIC-15 line, giving you safety, magazine release, and bolt controls accessible from both sides of the receiver. Combined with the Raptor ambidextrous charging handle, it's one of the most lefty-friendly AR-10s on the market.
Why does a 16-inch rifle have a rifle-length gas system?
It's a deliberate choice that pays off in shootability. The longer gas system softens the recoil impulse and reduces wear compared to shorter systems on a .308. Paired with the SLR Sentry 7 adjustable gas block, you can fine-tune the rifle for your specific ammo or dial the gas back when shooting suppressed.
