integrated recoil lug in aluminum bedding blockblock

Like I already said, OP, bedding your lug area can only help.

The fiberglass must just compress/move after a while. The rigidity must be the difference that matters. It was a better fit than any Vee block with more lug contact and side wall contact than your AICS. I understand a bent action can shoot just fine.Ģ) I assume you mean my stock not chassis. Ive always been one to say most accuracy comes from the barrel, barrel work, and many things other than the receiver. an aluminum vee block has good rigid contact and doesn't move when torqued down. there was lots of movement allowed between the receiver and chassis. 284?ġ)i hate to be the one to break it to you but the 'stress test' is not the end-all be-all indication of how a rifle will shoot.Ģ)your rifle didn't hold zero because it was not bedded at all. ĭid your mcm stock have an aluminum bedding block like the op's?Ĭare to guess how many times i've adjusted my zero in the 2900 rounds i have through my aics. This way your lug will always have 100% contact with the rear surface. Id bed the lug front and back, leaving the sides and bottom relieved. So I don't believe you can take an unbedded rifle out, shoot one days worth of groups, and say for sure that the rifle will continue to do what it did that day every day after. Once I bedded this same rifle, no more shifts. Then it would go back to half MOA for about another 200 rounds.

It would shoot half inch for about 200 rounds then Id have to pull it from the stock, and re-position it correctly, pulled to the rear, and tighten the screws back to 50lbs. I shot an unbedded rifle in an McMA5 for 18 months. Ive seen it matter and Ive seen it cause POI shift and groups to open up after a few hundred rounds.

Unbedded rifles can shift and move around. Originally Posted By: Keith at PCRJust cause a rifle shoots good one outing doesn't mean it will every time.
