I actually prefer the clamped front sight/gas block over the pinned and so does Krieger barrels. Take a look at their web site for an explanation.

I've competed with mine for two years, and in that time I've re-aligned the gas ports twice. Both times using red locktite on barrel/block and the bolts....I'm going back to my Colt HB





























, this was (obviously) strictly a range gun, going from vault to case to firing point and back again. Quite frustrating actually.
