This was put together by my Gunsmith who works for Windham Weaponry. He took these picture and gave a write-up while disassembling my Bushmaster Assault Rifle. I thought I'd share it with y'all.

Make sure weapon is unloaded!
With a small screwdriver carefully remove pivot pin clip

Push takedown pin out and remove pivot pin and separate upper and lower receivers

Push spring retainer in with a punch and remove locking yoke

Draw cocking handle back to the round cut out in the receiver and remove cocking handle

Draw the bolt carrier slide all the way out the back of the receiver

Push firing pin retainer out with a punch and remove firing pin

Remove cam pin and bolt assembly

Reassemble in reverse order.

Neato! Always have considered picking one up just out of pure interest.

Wow, thats a lot of little parts to loose if you are having mechanical issues in the field!

Very nice post. Thanks. Don't see many of those locally but BM AR-15's are quite popular.

I had one back in the 90's. The fire control group was primarily M16 parts.
it was suprisingly accurate. Piston driven IIRC.
