Remington 1100 experts, I need your help

[gunjunky]

Ok here is the back story. About 10 years a go I picked up a Remington 1100that had spent a number of years as an MWR gun onboard a ship. The gun is not in great shape but I only paid $25 for it.

Well I dug it out of the safe and now I want to get it back into good order with some changes along the way. I am cutting the gun down to be my new short (still legal) shotgun.

What I need are some pic's of the properly assembled gas system for the 1100. This gun had no gas ring (the o-ring) that is suppose to be installed and the piston seal assembly (the other two parts) were jamed into the barrel ring so bad I had to drive them out.

Want to make sure when the new parts get here I install them the correct way.

Thanks for any help.

My local library has Patrick Sweeney's "Gunsmithing: shotguns" and it has an excellent section on the 1100 gas system. Check and see if your library has it, or you could probably find a copy on amazon.com. It's hard to put everything you need to know into a forum post.

This post on another forum is pretty good, and it gives a link where you can get an instruction manual.

There are exploded parts diagrams at Remington's website. I've seen links posted here on THR. Either way, a little digging will get you what you want.

Details

The cutting of a barrel on a gas-operated mechanism has the possibility of inducing malfunction due to the reduction in gas pressure dwell time i.e. longer barrel holds pressure for longer time and effect.

Shorter barrels from the factory will have changes in the orifice size to ensure operation with the typical lighter loads intended to be usable. Target load barrels are a different story.

The other onion in your ointment is the clue of the sticking gas rings. If the cylinder is damaged, scored, pitted, rusty, and/or worn, or if the clearance is excessive around the mag tube section of the cylinder, extra drag may be induced or excess gas leakage may be present. Both situations increase the level of gas needed to reliably work the action, and may require a high brass load 1-1/4 oz., for instance.

Any cleaning in the gas cylinder should be with minimal abrasion and avoid hard wire brushes or abrasives, unless absolutely necessary to improve the surface condition.

1100 O-ring thread

Size 21 is 15/16" I.D. X 1 1/16" O.D. X 1/16" thick.

You can get O-rings at your local Ace Hardware. They may not last as long as the "right" ones, but they are cheap and and seem to hold up well enough.

# 21 viton, not buna rubber, is the correct O-ring for the Remington 1100. Very little difference in price and your local hardware can order them for you. They run less than $.35 apiece. I keep a few around if I need to replace one. They last forever, it seems. Buna, or plumber's o-rings, will burn through in a season of heavy shooting. Viton rubber will withstand the heat and last-I don't know how long. Never had to replace one. I do however replace them as a part of my annual tear down and cleaning. They look as good as they did when i put them in but to be on the safe side I replace them and carry an extra in my kit bag.

Be sure to tell the hardware store that you want viton, not buna, rubber o-rings. They will probably have to order them for you. So just buy a dozen for less than $5.00 and help your friends out when they need o-rings.

The number for 20 gauge is #19.

A rep from the gun company passed this tip to me after he retired.
