Ar-15 SBR Barrel

[tdale4]

After seeing a .300 whisper AR-15 the other day at the range I’m feeling the need to build one.

I guess I could go the M1S route, but I want a suppressed rifle that is also short. So I guess I’d be better off building my own upper so I can have what I really want.

I’ll be sending off my form 1 to SBR the lower I’m going to use for this project

Who makes an 8”to10” 1:8 twist barrels for the AR-15. I’ll primarily be shooting 220gr SMK’s, so the 1:8 twist will be an important part in getting good accuracy

Is it difficult to build your own upper?

Any suggestions would be greatly appreciated

Thanks,
Tim
