If your Browning Gold/Silver, Wi******er Super X2 -4 or FN SLP shotgun is not cycling properly, the cause if most likely the gas piston. The spring is either stuck or broken and allowing gas to bypass directly into the forearm.

The photos below show a Wi******er Super X3 gas piston with a broken spring that was sent recently to us for repair. The piston was disassembled, cleaned and sealed with our bushing.

The gas piston will now function properly for the life of the shotgun and it will be much easier to keep clean. The cost to seal these types of pistons is $50 and we usually ship them back the day after receiving them.

A guy shipped his A400 Xtreme to us because it wasn't functioning. This is what we found when we removed the recoil pad. The rest of the shotgun wasn't much cleaner.

Just making pawts.(parts) ( Ya gotta say it in a Boston accent)
Creating a specialty tool for removing the breech plug in a muzzleloader. Precision is key!!

Clients purchased three muzzle loader guns for a hunt in Idaho. The guns arrived non compliant with Idaho hunting laws for muzzle loaders with 209 ignition. After searching unsuccessfully for the CVA conversion kits, SRM Performance Products, modified the 209 ignition to accept a percussion cap ni**le, to make them legal to hunt with in the state of Idaho. Not only modifying the breech plug, but building the ni**les and firing pins from scratch! Thank you Jeff, Denny and Ernie!! They had all the parts made and heat treated and ready to fire in one day! Sighted in the guns today. They performed flawlessly! Have a good hunt guys!!
