    Quality carrier

    Posted by David Risher on 21st Mar 2022

    I did not buy this bolt carrier for the Colt pedigree. I couldn’t care less about prestige and pedigree. I care about components that hold up to real world hard use. That said I haven’t used this carrier yet. I keep spare bolts because they are consumable items. Started a new build, only needed a carrier as I have bolts. Side by side comparison of this carrier with some of my others makes me think this is made by microbest for colt. NO tooling marks, the chrome lining is smooth as glass, they key is straight, correct fasteners and proper staking. I haven’t used it yet, but if you need a carrier and no bolt, for the price I’d buy this one every time regardless of branding or pedigree.
