Just put front sights on a cpl rifles tonight. First was a '66 Glenfield Mdl 30 with frt sight dove-tailed into the round (pencil) bbl. Ended up using the 3/8" wide sight. Second was a Henry H001TM 22 Mag with octagon bbl. Put the 1/2" wide frt sight on that one.
Thoughts/feedback. The 3/8" was a tad to narrow and the 1/2" was a tad to wide on the Glenfield Mdl 30 rnd dove-tailed bbl - went with the 3/8" as 1/2" looked out of place/too wide. One the Henry octagon, 1/2" was also tad too wide and 3/8" didn't fill the slot or look right - went with the 1/2" wide on the octagon bbl.
Have you thought about adding a 7/16" wide front blade width option? I know the inventory hassles, etc. But if you do, I will immediately take a pair to fit both of the above rifles! Other than that, love your sights! Now have four sets on 2 Marlins, 1 each Glenfield and Henry, and will probably eventually take the scope off another Marlin and put Skinner peep on it.
