Bushmaster is not millspec but commercial, will this work with a bushmaster ar?
Answer:
If your Bushmaster AR is chambered in .223/5.56 NATO, then yes this will fit.
Will this work with an AR-15 chambered in .223 Wylde? I’m guessing yes but better if I ask.
Answer:
Yes this is compatible.
Will this bolt carrier fit a armelite ar-15?
Answer:
If it is chambered in .223 Rem/5.56 NATO or .300 AAC Blackout, then yes this will fit.
Would this be a good choice for binary trigger?
Answer:
Many binary triggers will run full auto and standard cut bolt carrier groups. This is a standard cut bolt carrier, so it will work with many binary triggers. However, some binary triggers require a full auto cut BCG and this will not work with those. You will need to refer to your owners manual to determine what your trigger is compatible with.
