Bought one of these BCG's and wouldn't go full battery with a round. Turns out the bolt lugs are out of spec. Should have been 0.273 but were 0.279 which 0.006 is huge when your talking headspace. Unusable bolt. Did have a 0.136 bolt face but comes with a full length fireing pin where as it should be a shortened 3.266 fireing pin to account for the deeper bolt face to prevent over striking.

I put this BCG in my aero Precision I actually dropped it on my concrete floor and it still works perfectly and no dent whatsoever very durable great for the price
