I am trying figure out what would be better for a 45ACP build, so far barrel is roughly 11". I am using an old Olympic AR15 barrel drop that I had cut down years ago.



So far, I just have it threaded for the extention.

Would an Integral suppressor be viable option for this project or just stick to a reflex/end of muzzle suppressor. I am going to use a Bear Creek Arsenal bolt action upper for this build so I don't have to worry about it cycling.

If you're ok with the length of a reflex, go integral.

You'll have the ability to make it a one-stamp gun, if you'd like.

Are you planning to shoot a specific ammo? This should a consideration when designing an integral.

Silencerco Osprey is stupid quiet with 45ACP and an 8" barrel on a DI gun, so I see no real need for a reflex on an 11" bolt gun.

If you want to go semi later, look at the work Rudy at Macon Armory has done with his DI 45 uppers.

My .45 setup here: https://c3junkie.com/?page_id=841
Using the CMMG RDB system that uses a standard extension.  No gas port hole to deal with.  If I want to make it a bolt action, I just swap to a .45Bushmaster bolt and it won't cycle.
