I was working on a pre-86 machine gun...Essential arms lower. The gun had an actual XM177e2 barrel on it, but on the end of the muzzle instead of a moderator it had a unusual Birdcage flash hider.
It had the same hole spacing as an A1 birdcage, but it had the enclosed lower portion like an A2. If viewed from the side you couldn't tell that it wasn't a standard A1. It had the larger A1 type slots...not the narrow closer slots found on the A2....anyone know if these were commercial or military? I have never seen a FH like it before. Anyone got any informatio on these?
It was highly unlikely any essential arms gun had a real XM177E2 barrel on it.
Can you post a picture of the flash hider?
I wish I had taken a picture of it!!! But at the time I wasn't able too and the gun went back to the customer.
The gun was a mix master only the lower was essential arms. It was one of there pre-86 full auto lowers. It had an actual Auto marked selector. The Upper was an Colt with forward Assist (no visible forge codes), flat slip ring, carbine hand gaurds no bayonet lug on the front site assembly which was milled. What appeared to be a XM-177e2 barrel, but with no grenade ring or moderator. And of course the weird flash hider.
Probably just an early non-Colt commercial flash hider.
There was a lot of crap being made in the 80's before things became more "standardized" in the AR15 market.
