shock buffer - pc challanger
I have outfitted my challenger with the shock buffer, red spring, bolt slide, magagazine release and they have each been a great add-on. Very pleased with this and other products added to other firearms.

Great product
I shoot my PC9 takedown suppressed with 147 grain sub sonic. This product took the plastic slap out of the bolt cycling. Pretty amazing. Super easy to install as all Tandemkross products are. I’m interested in getting the hi-viz sights next for low light shots.

It Works!
The name of the part says it all. It works. A must have part. Felt recoil is dampened. Big difference for me after I installed it. I'm hooked on TK upgrades.
