Hey guys,

I recently picked up a Remington 700 AAC-SD in 20" and in .308. Excellent rifle, very happy with it.

I am noticing an issue however, and could use some help in diagnosing the problem. After cleaning the gun, and inserting the bolt, I worked it a little bit just to see how it was wearing. If I cycle the bolt forward on an empty chamber quickly, the firing pin does not stay back. If I slowly do it, than it will remain in the rearward position. I can almost cause this to happen 100% of the time if I work the bolt quick enough, but has never happened if I work the bolt slowly.

This has never happened while shooting on the range, as I don't think I could run the bolt fast enough on a loaded round to cause the issue. But obviously until I can figure out whats happening, I won't be shooting it again.

A couple things to note
-Rifle has a drop in Trigger Tech with Safety installed. I am unfamiliar with how it works yet, but it feels like it is set as low as it can possibly go (1.5 lbs).
-This will not occur with the safety on.
-When I cycle the bolt forward, the firing pin still appears to be in place. It only moves forward when I lock the bolt down, and it only moves forward as fast as I lock the bolt. So I don't think it's slipping or letting go.

Apologies in advance if this isn't the place to ask. I'm trying to do some research before I ask, but I'm not exactly familiar with the nomenclature yet to know where to start. I can load pics if it helps anyone.

Thanks!
 
I had that happen when adjusting my Timney, turns out it was set too low made pull heavier by tiny bit and striker is held in place and safely functioning (not firing until trigger pulled).
 
Turn the weight of the trigger until it stops slam firing, its just set to lite, if you look at the base of the trigger shoe there is a small Allen key hole, turn it clock wise it wil have a very audible click and you'll be able to feel it as well, after each click test your bolt. Once it stops depressing the firing pin when you close the bolt hard you'll be good to go
 
Sounds like your trigger is adjusted too low. I had similar issue when I was tuning my Timney trigger. I just needed up up the poundage a hair and the problem went away. Contact TriggerTech and see if they can email you a manual for your trigger and then increase the poundage a hair until it becomes reliable.

Another thing is to avoid getting lube in your trigger group. Once it starts to dry out and get gummy (esp FrogLube and FireClean), it can cause similar problems. I had lubed up my 700 and had it stored for some time. The surplus lube had migrated and some ended up in and around my trigger group and it was a b!tch to degrease.

If you're not sure which is causing the problem, grab a hair dryer and warm up the trigger group until it is nice and warm. Work the trigger and safety to loosen it up then work the bolt and see if it locks up 100% reliably. If so, you might have an lube problem. If the problem persists, chances are you need to up the poundage on your trigger a hair.

If you're not comfortable with what you're doing, see a gunsmith.

Skip to 4:39 for safety testing.
 
Increasing the weight will likely fix your problem. However the trigger is designed to go that low. I would contact trigger tech, may need some warrantee work, or a slight adjustment.
 
Increased the trigger weight yesterday. Had no manual, but did figure out how to increase the trigger weight. Improved the situation, but didn't completely solve it so it may have to do with the Sear. I'm going to contact trigger tech and get their opinion on it. Will keep the thread updated.

Did you ever lube the trigger group? Did you buy/install the trigger yourself new or used?

It's a self enclosed drop in group, so not sure if lube can get in there at all. I did not install it.

My Timney is enclosed as well but I still managed to get lube in it. After a month the lube started drying out and got tacky and was causing the sear not to reset. I had to remove it from my rifle and soaked it in some naptha to degrease it. You'd be surprised how lube can get in there accidentally or intentionally.

I see. I'll have to try that

I got a TriggerTech as well, adjusted it to 1.75lbs. It would do that exact same thing until it was adjusted to about 2.7lbs (being i have no scale I dont know the exact weight)

It made me fairly apprehensive at first too...but the issue seems to have gone away by adding weight to the pull
 
I agree with guntech's post at the start of the thread. If the trigger is designed to go down to 1.5 pounds, it should be able to do it safely. And I wouldn't want to rely on a trigger that needs more tension on it to operate properly. It may work for a while or it may let you down again in the future and create the possibility of a very dangerous situation.

I'd be looking at sear engagement.

Hi,

Our trigger should not be lubricated, it is a dry system. The best thing you can do is put lighter fluid through it (it cleans and evaporates) and then spray some compressed air through it. Lubrication is never needed, we have stainless steel parts with a rolling system.

Cheers,

Hi,

Our triggers are designed to go to ~1.5 lbs. However, if your action is not timed by a gunsmith, you have to cycle it gently below 2.5 lbs to not experience following of the pin. To be clear, this is not a safety concern, as the trigger just doesn't ####. There will be no AD from this occurrence, it is just a nuisance if you want to roughly cycle your action at low weights. As in, you will have to re-cycle more gently to properly #### your rifle below ~2.5 lbs.

The following issue (happens to many triggers below 2.5 lbs) is when the firing pin assembly hits the sear of the trigger prior to rotating the cocking arm. This shouldn't happen in a timed action and the sear should only be engaged when the cocking arm is rotated down. When the trigger is set heavier (~2.5 lbs+), this issue shouldn't show itself, though the occurrence is still happening within the system. Again, this is common to most all trigger systems.

It should not follow at ~2.5 lbs or above. Feel free to email at anytime info@triggertech.com

Cheers,

TT
