    Barrett claims 1 MOA with match ammunition

Believe it or not, the M82A1 is not that bad to shoot. The spotter actually suffers more than the shooter (Due to the muzzle brake sending the concussion out and back, usually right into the spotters face). While the potential for extreme long range shooting is there, the current military ammo is not up to the task. There is no military match ammo, and that really kills the accuracy potential of this rifle. Even with match ammo, the rifle will have a hard time holding its claimed 1 MOA, there is just too many moving parts. But, for its designed purpose as a long range hard target interdiction rifle, the M82A1 is hard to beat! Its semi-auto, 10 round capability against a light skinned APC is outstanding.


I do not consider .50 BMG rifles true sniper rifles, they are much too large and heavy to be carried easily and effectively while a sniper team operates. I do feel they have an important role and should be in the inventory, but don’t fool yourself into thinking they are an everyday sniper rifle. Use them when the mission dictates, which might include overwatch positions (where little movement is involved), defensive positions, small hunter teams searching hard targets (where more then just the sniper team goes out), etc. Because I do not consider the .50’s a true sniper rifle, I have not really included any on my page, but the M82A1 is used by just about everyone, and its what I’ve been trained on, so I have included it on my page.

UPDATE The US Army has officially adopted the M82A1 as their special purpose long range sniper rifle. Believe it or not, a bolt action won the trials but for reasons not entirely clear, the US Army decided to adopt the M82A1M (The M has a few modifications over the USMC M82A3). The official designation for the rifle is XM107 Long Range Sniper Rifle. The max effective ranges are listed as 1500 meters at materiel targets, and 1000 meters at personnel.

We have shot them and for a basic single shot 50BMG, they work fine. Recoil is manageable and accuracy acceptable.


Fun to shoot. Accuracy about 1.8-2.1 MOA with Hornady Amax 750’s. Nicest feature–you can drop a lot of quality triggers into it. We use a Jewell set at 2.5 lbs. Takes the anticipation out.

I had to take ours to the gunsmith to have the bolt lapped. Got tired of slamming the rounds in to lock the bolt. ‘Smithy said the headspace was zero plus ‘nuthin. Works like a charm now!


We recently bought an M107A1, which is very similar to the M82. If the 107 is supposed to be more accurate than the 82, I can’t believe Barrett is touting the 82 at less than 1 MOA! Best we could get out the the 107 with Hornady Amax 750gr is around 2.5 (and only after getting used to the crappy trigger). Searching the forums I found about the same. Speaking with a Barrett tech (who was very helpful), he said that’s about what to expect unless you reload–and then MAYBE 1.5-2.0 MOA. I suspect that’s about the same for the M82.
