remington 1100 question

[Virginian]

There is only one (1) 'O' ring in the entire system. Go here -
www.remington.com
and download an owner's manual. Read it well. Do not slide one of your fingers inside the receiver cleaning things or the sharp edges on the link grooves will cut you - of course it is a Remington 1100 owner's rite of passage. Do not drop the hammer with the trigger group out of the gun or no bolt in the receiver or you will bend the carrier latch and create a malfunctioning 1100. You won't be breaking new ground there either, but why do it? 'O' rings - Viton - are available on eBay for $6 delivered for four. A lifetime supply. The 'O' ring does not move in use. They get shredded by ham handed people when the disassemble the gun and put it back together. You do not have the "newest" semi auto design around, but there are none that shoot any better with a little TLC. Good luck..

You should be good to go with any 2-3/4" ammo. The design is self compensating to that degree. Make sure the splits on the piston and piston seal are 180 degrees apart. Spray everything with RemOil and wipe off all the excess and you should be good. I do this after shooting every time and get no hard to remove junk built up - takes less than 5 minutes. You hear a lot of crap about 1100s, but I have managed to shoot one - the same one - for 48 years with no problems, with 8 others along the way as well, with only a couple of minor issues over 30 years back on the last (broken extractor). I still think a lot of it is sour grapes for Remington running the Auto 5 and the Model 12 out of the market. They took over the skeet fields and flooded the hunting grounds after they came out like nothing before or since. If it was the jam-o-matic some people claim it would never have dominated in competitive skeet - you get no alibis. Through the '70s a lot of guns came along that the salesmen touted as the 'one' that was going to make the 1100 obsolete, and they all went faster than they came. Remington haven't felt the need to change everything every few years and come out with something even "mo' better" like a few Italian guns I know, and that bugs some people too. No, it won't go 500 rounds between cleanings, but neither will I.
I hope you enjoy yours in good health.
