Groups between 1/4 and 1/5 MOA at 900 yards using issue .50BMG machinegun ammunition. Hmmmm...
I'd be surprised to find that GI issue .50BMG ammo from that era would shoot better than 1.5-2MOA regardless of what it was fired through.

Never heard of a pistol grip for the M2, so, either something the Army dropped before my time, or possibly a local made thing at the unit level. Quote:
To the best of my knowledge no M2 .50s were mounted on Hueys during the VietNam era. Door gunners had an M60 though sometimes the M60D with the apade grips. Gunships had a pair of M60s in fixed mounts on each side, usually dispensing with the door gun, but any variation is possible, GIs can be inventive.

The only helicopter that I know of that had .50's mounted on it was the ACH-47A. These were a test program and only a few were made to test in Vietnam.
The ACH-47A's were attack helicopters, they had 40mm grenade launchers on the nose, 2.75 rocket launchers on the side and either M60's or M2's on the side doors/windows.

Pete
I knew you were jerking my chain , made me laugh. The 50 was the king of the jungle as far as I'm concerned, no place to hide . We had gun trucks with a 50 and 60's supporting convoys , I saw aduce an ahalf with a quad 50 , looked like something you would see on a ship . Never road on one but sure would quiet things down . Never saw a ma on a gunship but I'm sure it could be done.. Stay Well. Chris |

I just so happened M2s and 40mms were my specialty , Duster Quads. 1/44th & 4/60th RVn.M2 with brand new barrel, shovel handles and optic sight was lucky to do 12” at 100yds off solid mount. I never saw the sniper trigger unit outside of training in the states. It was either shovel handles or solenoids, for us. It’s not something every unit would have, its special issue. Starlights were even harder to come by. I still have my M2 gauges that I carried with my dog tags. No Go & Go gauge and feeler gauge for firing solenoids in Quad mount. We were on a hill top and blew a side door on the 40s. A team from Ord, came to repair gun. Warrant officer was head man. When done they had to use bore sight set to regulate guns. They did and then shot a game of splash with the 40s. Only on a water Buf not a duck. They scored direct hit and hauled ass. We caught the backlash from it and our X0 had to come from HQ and pay dinks damages.

Shooting ball out of 'match' guns (in particular that are on sleds / locked down) tends to prove that. What that creates is a most lethal shotgun with a 1+ mile effective range.

catch
Did anybody catch that in post #3, the OP stated that he thought the 2 MOA claim was in regards to a personally owned weapon the acquaintance had AFTER Vietnam, not as a door gunner?
But the thread has made interesting reading, none the less. |

Carlos Hathcock did hit an NVA at 2300 yards using an M2-weight about 81 pounds-mounted on the tripod-40 pounds-with a 10x Unertl scope from a hilltop. So he had a securely mounted weapon with a clear field of fire. Given that probably all the M2s used in Vietnam had probably seen service in WWII and Korea, and their barrels were probably not checked for wear and erosion.....
I have heard the "they could use ours...."regarding the mortars, I rather doubt their designers thought about that. The one I heard was you could fire a 5.56 round out of an AK-with what sort of accuracy ? |

Half the area of a 7.62 barrel would be empty as a 5.56 bounced along the barrel with most of the gas escaping...
