Barrel Nut Shims are a great compliment to any Free Float Rail . If your forearm doesn't have the ability to "time" the position of the forearm in relationship to the gun, or shim will give you this capability. stainless steel shim fit between the barrel nut and upper receiver to allow the user to adjust the relationship between the gun and the forearm features like swivel studs, vent openings, and picatiny rails, to the shooters needs.

Shim thickness
Shims all miked .011-.0119. 2 ea lined up my hand guard. I got lucky. Might be better if kit included a variety in shim thickness.

Used this to rebarrel a Ruger No. 1V
I had a Ruger No.1V in 270 Win....I know, rare as chicken lips...but the barrel was done. I found a barrel in 300 Win Mag for a good price and the heads pace was off byjust under .003" . I polished one of these spacers a few times, got the ruger to head space AND clock in...viola! Varmint rifle is now Elk rifle!
