Purchased a second set of handguards to stipple with a bit more of a mature/M1-ish layout, while preserving the originals. Apparently the “NEW” handguards purchased were of an older iteration, because they would not fit, as the mold did not have the notch for the barrel indexing collar. I fit the handguard and no one would be the wiser. Added a match saver, having to counter sink the nut to avoid piston contact. It worked well, but in hindsight, I wish I would have stuck to Velcro, given acceptance of Velcro as an accepted means for side saddles.
