Description
Few rifles put reaching-out-past-a-mile within grasp the way the ArmaLite AR-50A1 does. Built around the .50 BMG, this is a single-shot, bolt-action rig designed from the ground up for precision at distances where most rifles quit. The heart of it is ArmaLite's octagonal receiver bedded solidly into a V-shaped aluminum stock, with the 30-inch chrome moly barrel free-floated above the forend so nothing touches it during the shot. That combination is what gives the AR-50 its reputation for putting rounds where you point it.
What Makes the AR-50A1 Manageable to Shoot
The .50 BMG has a fearsome reputation, but this rifle is engineered to keep it civilized. Between the roughly 34-pound weight and the huge multi-flute Recoil Check muzzle brake, felt recoil comes back as a firm shove rather than a punishment. The action runs a triple front locking lug bolt with a Sako-type extractor and spring-loaded plunger for automatic ejection, and the newer A1 bolt stop can be pressed by hand to drop the bolt. The Shilen standard single-stage trigger breaks at around five pounds, which is a solid pull for deliberate long-range work.
Setup and Portability of the AR-50A1
The three-section stock is a smart touch. It uses an extruded forend and a machined grip with a vertical grip, plus a removable buttstock that shortens the rifle for transport and storage. Overall length runs 58.5 inches with the stock on and drops to about 49.8 inches without it. On top you get a 15 MOA sight base slotted for a MIL-STD 1913 rail, so there is built-in elevation for stretching your dope way out there. All aluminum is hard anodized and the steel wears a manganese phosphate finish, so it holds up to hard field use.
This GG&G-equipped version ships with the heavy-duty bipod already accounted for, with legs that adjust from 7-7/8 to 10-1/2 inches for a stable platform on the bench or in the prone. Backed by ArmaLite's limited lifetime warranty, the AR-50A1 is a serious entry point into big-bore long range without a custom-build price of admission.

Frequently Asked Questions
Is the ArmaLite AR-50A1 really manageable to shoot in .50 BMG?
Yes, more than most people expect from a fifty. The heavy 34-pound platform soaks up a lot of the energy, and the massive multi-flute muzzle brake redirects gas to take the sting out of felt recoil. It comes back as a strong push rather than a sharp jolt, though hearing protection is a must with a brake this aggressive.
Does the AR-50A1 come with a scope or sights?
No, it does not include a scope, and there are no iron sights. What you get is a 15 MOA sight base slotted for a MIL-STD 1913 Picatinny rail, which gives you built-in elevation for long-range dialing. You will want to add a rail section and a quality high-magnification optic rated for heavy recoil.
What bipod comes with this version of the AR-50?
This GGG model ships with a rugged GG&G bipod and adapter designed specifically to handle .50 BMG rifles. The legs adjust from 7-7/8 to 10-1/2 inches and install without tools, giving you a stable base on the bench or in the prone.
Can the AR-50A1 be broken down for transport?
It can. The three-section stock uses a removable buttstock, which drops the overall length from 58.5 inches down to roughly 49.8 inches for easier storage and hauling to the range. That is a nice feature on a rifle this size, since it makes fitting it into a case a lot less of a chore.
