New rem 700. 15th round shooting I pull the trigger and hear a click. :confused: I pull again and it acts uncocked. I was prone, get up on my knees to eject a round and inspect it. Im not touching the gun and it’s been 10+ seconds. I put my hand on the stock and Boom! I screamed bad words, spiked my ear protection like a football, then was really glad I kept the gun pointed towards the burm.

1.what happened?

2. Would putting the safety on, prevented the fire pin from releasing even though the trigger was already pulled and uncocked.
 
Will a high end aftermarket trigger take care of it? The factory trigger feels good enough to me. I don’t know if that’s a trigger issue or a fire pin issue
 
I’d inspect the pin to be sure it’s not sticky or hanging up. Then I’d run a box down stream to see if it happens again. Possibly the round maybe. As long as your bolt is in full battery when it happens I wouldn’t worry but definitely keep it pointing in a safe direction. Or contact Remy about it if you believe it’s the firearm and not the ammo.

The firing pin was back, when I touched the gun it released. So it can't be the ammo, right?

How do you know the firing pin was still back? I’m not saying it wasn’t but I wouldn’t rule out the ammo either

We looked at it, then I reached down and touched the gun and it went off. See below

Supposedly they fixed that issue and recalled all the SN's, but what you're describing sounds a lot like the old problem.

those problems were with the "Walker" triggers and they were supposed to be fixed years ago. i wouldnt expect it to be the same issue with a new trigger design. Brand new gun? id imagine a metal shaving or something blocked the hole for the firing pin extrusion. and then it didnt after he "slightly" bumped it.

strip the bolt down, clean completely, blow out the bolt body, etc.

it sucks that it happened but it was pointed the correct way.


why didnt the OP open the bolt before getting up from the gun to show everyone it was all clear?

aftermarket triggers will fix any trigger issue that you feel you have. i think you had a bolt/firing pin issue.

if it had fired when you closed the bolt or released the safety, id say that was a trigger issue.

We discussed that afterwards. Mostly confused at the time. The gun sitting their down range and me off it, it was reasonably safe at the time. When my friend pointed out the pin was back still that’s when I reached down to open the chamber and it fired. We both agreed opening the bolt should have been the move. and would be if it happened again

That also prompted my safety question about if it still would have fired like that if I put the safe on.
 
Opening to bolt is the wrong move in my opinion, in the case of a hangfire or light primer strike you are supposed to keep the rifle pointed in a safe direction for a minute.
seeing as how it wasn't actually a hangfire, but the firing pin not falling the round will never go off until the firing pin goes. If it moves forward while you are unlocking the bolt you're going to have a bad time. Maybe have your friend smack the side of the action while you are still holding it.

Sounds like a firing pin issue over a trigger issue. Take apart the bolt and firing pin and make sure there aren't any burs or excess grease on it or the spring.

As soon as the bolt starts to lift, the cocking piece would hit the cocking ramp, not allowing the firing pin to protrude.

I’m a bit skeptical of the chain of events, but at a minimum I’d pull the firing pin assembly and make sure it is clean. Put a bit of high pressure grease on the boot shroud threads, reassemble and go shoot.
 
disassembled, cleaned, polished, greased the bolt/pin assembly this morning.

I found a shiny small metal shard in there. Looked like from manufacturing.

You should be skeptical. the guy with the ffl who has dozens of high end target guns and only runs rem 700 has never seen it before and he watched it from 3’ away.

Not an indictment on your friend in particular, but holding an FFL means fuckall to your knowledge of firearms or what you've seen or not seen.

Agreed but His experience is important. I’m not saying he’s a gun smith or the best but he’s deep into 700 custom precision stuff. His 575 yard range is nice and gets used. Been in magazines a few times, featured once. He practices trigger pull while I’m watch TV. My point was I had a knowledgeable guy who with me who watched it and was confused by what happened and how.

i own no actual Remington 700s, i dont have an FFL, and the range that i own is nice and goes from 50 yards to about 450 and gets used less than i would really like, and I had your problem "pinned" down about 5 minutes after reading your story. :flipoff2:

glad you got it fixed. Multiple-time-bankrupted Remington super awesome "i cant believe they cant make money" quality control strikes again.
