Intended as a replacement pin for current Centurion Arms in-house pinned gas blocks for our customers who lose, damage, or just want an extra on hand. These are not replacements for MK12 gas block pins nor FSBs.
Some good things have to come to an end and we are saying goodbye to our long standing method of pinning our in-house gas blocks with a taper pin. All newly top-pinned gas blocks will be using our new heavy duty double coiled spring pins. These pins are not interchangeable and if you are in need of a replacement for an older taper pinned gas block you can find the taper pins HERE.
Please note that some barrels in stock were pre-pinned prior to this change and will still have a tapered pin in use. Make sure you thoroughly inspect your gas block set up before ordering.
