I got a Remington ADL SPS in 223 from a pawn shop for about $300.
I like the barrels to be free floated so I started by removing the little bumps in the front of the stock, tested and repeated about 3 or 4 times to no avail!
I put it in my mill and removed another .060” and a piece of printer paper now clears all of the way to the recoil lug.
I have never had to do that with any other 700!
