1. How Do I Install the Tom Cole Heavy Duty Gas Piston Rods?

The install is not that difficult but you need a drill press and welder to do it properly.
- Drill out the dimples in the bolt carrier . Unscrew the factory rod.
- Dress my new rod to match the thread profile of the factory rod.

The Solvent Trap adapter is hexagon shape with 1/2 x 28 threads. It threads on to an oil filter for the purpose of trapping the solvent.

The Econo-Can Suppressor adapter part is round in shape. It also has 1/2x 28 threads and threads on to an oil filter for the purpose of shooting though the oil filter and working as a silencer. The adapter part also has the manufacturer name Cadiz Gun Works, Jewett, OH. Each Econo-Can Suppressor has a unique serial numbered that corresponds to respective the oil filter.

5. What does Reliability Service Include?

Cadiz Gun Works does still work on the Saiga shotguns. We are no longer the warranty provider for Russian American Armory or any of the current importers. To see about warranty service you will have to contact the importer. Importer information can be found on the side of the receiver on your gun.

We tune the guns to cycle the Federal, 12 gauge 2 /4, 1 1/8 oz, #7 1/2 or #8 loads. These can be bought at Walmart in the bulk packs for about $20.00 to $25.00 per hundred. The gun usually does not like to cycle on anything less than 1 1/8 oz loads. The 7/8 oz, 1 oz and low recoil ammo usually has feeding/cycling problems.

The turn around time is 220-250 days. You can keep your gun until we are ready to work on it. We will contact you via email or telephone you when we are ready for your gun. All we require at this time to hold your place in line is a $50.00 deposit, which will be applied to your Reliability Service
