Rifle fires while closing bolt

[codemancode]

Recently installed a Timney 510 in my Rem 700. I installed it right out of the box without making any adjustments to the pull weight or sear engagement. Occasionally the gun will "fire" when closing the bolt. It tends to happen when lowering the bolt to its locked position and happens on an empty chamber as well as a loaded chamber. When the hammer drops on a loaded chamber it does NOT fire the round so i'm guessing the bolt isn't in it's full downward position when it slips. For some reason i can simulate the effect very easily when i direct the muzzle upward(empty chamber of course). With the muzzle pointed toward the sky i can basically cock the gun and fire it by just raising and lowering the bolt handle. If i move the bolt incredibly slow it acts normal, but any kind of speed will cause the issue.

Is this an issue with the sear engagement that i can fix myself or is some else wrong? Any ideas?

From what I remember, Remington was having this problems with several of their 700's and I think a few people actually got shot. I would contact them before using your rifle again and get it fixed! Goodluck and be careful!

How exactly would this be Remington's fault??

I would recommend you call Timney. They are very helpful and more than willing to talk you thru adjusting the trigger over the phone. I've had to do it before but not for the issue you are experiencing.

You don't have enough sear engagement.

You have insufficient sear engagement. If you install that trigger in 10 different rifles it will have 10 different pull weights and the creep and over travel MAY be different as well. Easy fix though.

Unfamiliar with Timney but if you can adjust overtravel and sear engagement before weight of pull, that should cure the problem. In any case, the Remington trigger is just as good if not better and you can usually adjust one down to about a pound and a quarter, if you are careful. You need to test it repeatedly though, drop the butt on a hard surface, close the bolt as fast as you can, stuff like that to make sure it holds, no matter what. I'd return the Timney, if you can't figure it out. BB

"You don't have enough sear engagement."

^^^ This

It is possible that the trigger came with incorrect adjustments. They should be drop in factory adjusted to 3 lbs.(although trigger pull and sear engagement are two separate adjustments)

Best answer is to take the rifle to a qualified and competent gunsmith and have him take a look. He may be able to adjust it for you.

Other than that give Timney a call and let them know what you are experiencing and maybe they will exchange it for you.

Here is a good vid on installation and testing the Timney with Rem 700, If the rifle does not pass the various tests, it is UNSAFE.

Either take it to a smith, or call Timney, do not change or adjust anything until you do one or the other.

Lastly this has nothing to do with the Remington trigger craziness, hopefully the thread does not go down that road.

Good Luck
