I'm looking at putting together a 9mm AR pistol and I was wondering about barrel and muzzle device installation. How do you do it with a non-standard upper (won't fit the clamshell, can't use BEV or reaction rod)?

This is what you are looking for. It will also work for 308 ARs |

I use the white delrin DPMS upper receiver block, it works great but it seems to be out of stock everywhere.
The clamshell will work, it just needs to be notched for the 9mm gas deflector if you have one installed. That's how I did my first few. You can also use barrel blocks instead of an upper block, that's technically supposed to be a better method anyway. |

This. Found one in a local gun store a couple weeks ago when I faced this same dilemma. Works like a charm. |

Quoted:
You could also remove the gas deflector and reinstall afterward. This is what I do, just remove the gas deflector and put it in regular clamshell blocks. It's very possible to break your upper using a device like the ebay link or DPMS block. Example: https://www.ar15.com/forums/t_3_123/627276__ARCHIVED_THREAD____Broke_my_upper___.html&page=1 |
