Frequently Asked Questions

What is the main difference between the old and new Remington 1100/1187 gas piston systems?

The older Remington 1100/1187 gas piston systems used two separate steel rings. The updated design integrates these into a two-piece interlocking steel unit that snaps together for easier assembly and potentially improved durability.

How do you assemble the new Remington 1100/1187 gas piston system?

To assemble the new two-piece piston, align the outside bevel of the back piece with the inside bevel of the front piece. Press them together firmly until they snap into a single, integrated unit.

What is the correct installation order for the new Remington 1100/1187 gas piston system?

When installing the new piston system onto the shotgun's magazine tube, the large flat bottom of the assembly should be placed first, bearing against the action arm. This is then followed by the installation of the barrel seal O-ring.

Is the new Remington 1100/1187 gas piston system compatible with older shotguns?

Yes, the new style piston system is fully backward compatible with older Remington 1100 and 1187 models. Once installed correctly, it functions identically to the original design.
