Well should say back dating so to speak. This is a 1991 Preban Sporter competition Hbar. It has the shear block and half moon carrier in it and shaved bayo lug. I love the look of a sp1 but hate the pencil barrels. Everything I replaced I did so with original colt parts.
I changed the round handguards to triangle ones. I swapped the bird cage out to a 3 prong with correct split washer. I changed the forward assist to the teardrop and changed the charging handle to the early triangle. I also swapped the the grip to the A1. The triangle charging I like better then the standard. I’m pleased with the look and will call this my SP1 Hbar
