Have a AR carbine that I assembled in 45acp 16” barrel blow back 10once buffer and 308 carbine spring. Snapped off the BHO part, replaced it with a badger ordnance billet one no problems. Also have the same set up
In 10mm never had a problem with it breaking BHO.
Just recently I have assembled another AR45 in pistol form with a 8” barrel and it also broke the BHO part.

Anybody ever had this problem with a AR in 45acp?

TIA.

How far behind the bolt stop does the bolt travel?

Just enough to clear it.

Have you tried a 5.56 spring?

Nope but I think I’ll give it a shot though.

I had to put 2 quarters in my buffer tube. Haven't had a problem after that.  Broke probably 4 prior.  Locks back exactly when it hits full rear travel now.  Once the bolt starts moving forward, that's a lot of mass to stop if it has any room to accelerate.
