I think I pretty much have a handle on what goes into a 9mm conversion. Here's my plan, tell me where I might be going wrong:
- Rock River Arms 16" carbine barrel
- CMMG bolt
- Spikes Tactical magwell adapter
- modified Uzi mags
- H3 buffer (because I have one already)
- 9mm ejection port door
- 9mm gas deflector
I already have a spare A2 upper receiver laying around, so I'll use that. Is it necessary to block off the gas tube hole? Is there a good way to non-permanently do that? Could I run a bolt from inside the receiver and use a lock washer/nut on the outside?
I've read that seven quarters work well as spacers in the buffer tube. Is that a good starting point?
Should I get stronger hammer and trigger pins for the blowback action? If so, where should I get these?
BTW, a short barrel is not an option. It's definitely going to be 16".
Thanks!
