| See if any of you guys can figure this out, because I'm friggin' flabbergasted. I finished building a retro 'Pre-Vietnam Prototype' XM-16E1 with an NDS-32 carry handle 'trigger' charging handle upper receiver. I used an A1 stock with a rifle-length extension & same-same on the buffer. As far as I know (unless I'm missing something obvious!), all the parts I used appear to be correct. Here's the problem: when I pull the BCG back to chamber the first round, it BOTTOMS OUT about 1.5 inches short of clearing the ejection port. And, of course, the buffer is slamming against the rear inside surface of the receiver extension. WhatTF??????:confused: |

Sounds like your buffer is too long. Are you sure you're using the correct buffer?
Stupid question, you seem to think you are at least. It doesn't make sense that if you have a rifle length buffer and buffer tube that you'd be having this problem. Is the buffer tube free of obstructions? Is the spring correct? |
| Again, unless I'm in serious FAIL mode, in order to have an A1 stock fit correctly, there would have to be the right ext. tube on there, right? And the buffer, itself, is the long one with the "flange" about 1/3 of the way behind the BCG contact surface. As far as the spring, even if it was the wrong one, that wouldn't have anything to do with the BCG stopping short of clearing the port, would it? It must be the buffer, but the only option would be to put in a shorter (read: CARBINE) one to compensate for the "gap" that is now taken up. But how will a carbine buffer work in a rifle-length system??? |
