Ahhh, interesting! I just ordered this kit, same reason, price caught my eye; willing to put up with some annoyance for 540 shipped.
Now just a matter of figuring out how to get a handguard to fit… savage one, based on pic rail copy, paste, and count, is roughly 12.4 on the underside, cut back to 10.2 (ish) to clear the block… wonder if smoke composites could do a rifle diameter version of the cut-back brekke customs pcc handguard… or not, maybe. Seems like it would eat up anything I saved going with the kit in the first place…
Other option might be to see about trying to find the adjustable block off of the savage Valkyrie long range upper… that one looks like it had the same mechanicals/attachement, but in a smaller package to fit inside the rail…
