I have a 16" midlength gas upper with less than 100 rounds through it. The upper came off a complete Armalite rifle but had an A2 upper. I had my gunsmith change out the A2 upper with a new BCM M4 flattop upper with M4 feedramps. The upper is the latest style and is marked “BCM4” on the front by the gas tube. The barrel is a standard Armalite 16" midlength USGI 1/9 twist chromelined barrel with A2 flashhider. Less than 100 rounds of quality brass through the upper total. The only thing it has is a small rub mark through the finish on the delta ring. Other than that it looks great. It will come with the original set of midlength Armalite handguards. NO BCG or CH

Only trade would be for a BCM 16" middy with LW profile barrel with fixed FSB.
