Remington model 1100

[nightbuck]

I shot a Remington model 1100 12 gauge auto that had a terrible hot gas blow back problem. The hot gas burnt my eye badly when the spent shell was ejected. Learned to wear shooting glasses pretty quickly. The gun worked well except for that. Any suggestions as to what was wrong or a fix?

Definitely not normal. Where did the gas come from? What kind of loads? Gas pressure should have dropped to zero at the breech before it opens. Are gas ports clogged? Trying 3" magnums in 2 3/4" gun. Need lots more info. BTW, always wear eye and ear protection. My granddaughter shoots my 1100 in youth league trap left handed and experiences no problem with the right handed gun.

Look at the manual and make sure the parts under the forarm are there and in the correct position.

I’m in agreement with PapaG. Take the barrel off and look at the gas ports. Having hot gas blow back is not normal. The o ring could be missing or worn out and as 243 stated it could have been reassembled backward.

As everyone thus far has suggested, remove the forearm, makes sure all parts are present in in the right place. If this is so, look at the gas ports in the barrel. Plugged? Was the forearm installed correctly? Not doing so can shoot gas straight back at the shooter. I have shot 1100's both right and left handed and have never had that happen. If none of these conditions happened, it could be bad ammo or incorrect ammo. (3" in a 2 3/4, though I've done that, and got a sore shoulder and the hull woudn't eject)

Could be someone drilled out the gas ports to shoot mouse fart loads and you are shooting normal loads. Seen it before.

I bought a "broken" LT20 1100 that had the gas ring installed backwards, so it jammed with every pull of the trigger and was a single shot. I flipped the offending ring around, replaced the rubber "O" ring and away it goes, flawlessly. Best $250.00 buy I've made yet on GB.com.

Always start with the assembly of the gas-action parts after a good inspection, as was earlier stated. If all is kosher, then check the gas tubes for blockage or tinkering as was also stated. After that, check your ammo... then if it's still blowing back into your face find a good 'smith who can figure out what's going on.

Stay safe!
