I’m wrapping up an Aero M5 upper and lower build with an 18” criterion .308 barrel. I want a bcg that I can squeeze every ounce of accuracy out of. Can someone recommend a Bcg that fits well with criterion barrels?

I wish I had been able to purchase the barrel with a matched bolt, but that wasn’t an option.

Also, I’m planning a second AR10 build in 16” and will need a BCG for general plinking and hunting. What’s a solid budget BCG that will function with a PSA upper with an after market barrel?

Other than the price of admission, you will never go wrong with a JP bolt and carrier.  Just decide which one you want.  Plus, they are beautifully machined and finished.

I'm really impressed with RCA's BCG in my Creedmoor.

I used an Aero High Pressure BCG with my 6.5 Creedmoor Criterion barrel. My last range trip I shot these two groups at 103 yards.

10 shots.

5 shots.

Both groups were shot while checking/adjusting zero before heading to the longer range steel.

I use the MWS lightweight BCG in my 7mm SAW.
Works great and has less reciprocating mass.
