Gunsmithing R700 trigger adj. problem with sear engagement

[taseal]

I'm following the insturctions from the url that most people use (http://www.quarterbore.com/library/articles/rem700trigger.html)

well when I get to the part that I gotta put the bolt in and close the bolt, the pin drops already. I can't keep it out so that it doesn't. see what I'm trying to say? the sear isn't holding the pin, when I turn the bolt to close it, the silver piece in the back of the bolt just goes forward

any help with this?
<span style="font-weight: bold">
ETA: ok I got it.</span> I had to put more tension on the trigger screw. there is very little creep (if that) on the trigger. not sure if it's supposed to be like that, I don't mind it. perhaps pull the stop screw out a bit?

Re: R700 trigger adj. problem with sear engagement

I'm no expert, when I adjusted my trigger it would do those things you described if the pull weight or sear engagement was too lite. Just make sure the it won't drop the pin when you slam the bolt forward and down really work it hard and fast. Really press it forward as you lock it down and make sure when u take the safety off it won't drop the pin either. Make sure its safe. Safety is more important than the trigger pull

Re: R700 trigger adj. problem with sear engagement

man I slammed the hell out of that thing. back and forth (and closing the bolt of course)

however if I put alot of force on the bolt forward, the pin does not 'cock' it just goes back in

but if I slam the bolt and close it, the pin stays cocked.

working the safety, it was ok as well.

pull the trigger, let it 'fire' then without moving the bolt back, put ALOT of forward pressure and just work the bolt. don't pull it back and push back forward. just work the bolt knob.

I also just went outside and in the cocked position, I kept dropping the barrel (few inches high) to hard surface. the pin dropped. I did few more adjustments and now when I drop the bolt, it won't drop the pin, but now there is a very slight creep on the trigger before it breaks. I moved the trigger stop screw a bit, but it's on the edge already, if I move it 1/10th of an inch, the trigger doesn't pull.

I got it right at around 2 to 2lbs 4 oz area

I wouldn't mind it lighter, but I wanna get comf to such low lbs for triggers. I did some washer drills (if anyone knows what that is) and that thing is def light. but I wouldn't mind if it was a bit ligther lol

Re: R700 trigger adj. problem with sear engagement

yeah I've been messing around with it for a while. no matter what it's at, without the safety, if I drop the barrel with nothing to take the vibrations from 5 inches or so, the pin drops. with the safety on, it's no issue at all.

the lowest I can get it is around 2Lb to 2Lb4oz anything lower than that (I tried to get it into lower than 2, around 1-10 to 1-12) but i just can't do the slam the bolt and close it drill. once out of 5 times it wouldn't cock...

oh well, 2 lbs is still better than the 6.5 that I got it with lol

Re: R700 trigger adj. problem with sear engagement

Two lbs is pretty light.

Do you have an x mark model trigger by chance? I had a similar experience with the 2nd gen x mark that came in my rifle, only we couldn't get it below 5.5 lbs without creep. There's a Shilen in it's place now.

Im no smith, but it sounds like you need to gain a little sear engagment. I'd probably give it a 1/2 turn or two back out and work with the poundage screw. Especially if thats a hunting rifle.

it's a 2001 rifle, so not X trigger.

I added some more sear engagement.

it's not a hunting rifle, but a benchrest/SHTF rifle.

Re: R700 trigger adj. problem with sear engagement

Assuming it's a trigger issue only, there's only so much you can do with the factory Rem 700 triggers. Don't expect it to get you to the point that you might with a fine high end trigger. The amount of sear engagement and the weight of pull are interrelated settings and either one can cause the firing pin not to hold when you close the bolt. The trick is finding the best balance between the two settings to get (1) a lighter trigger, (2) with no creep, and (3) that will hold back the firing pin when you close the bolt any way you do it or try it. Too much or too little of either setting (sear engagement or weight of pull) puts things out of balance.

Re: R700 trigger adj. problem with sear engagement

it sounds like the trigger return spring is maxed out in tension and not fully seting the trigger forward, letting the sear drop.

you can try this kit:
http://www.midwayusa.com/viewProduct/default.aspx?productNumber=654821

replace the factory return spring with the reduce power one, it's slightly longer so you can back the wieght setting out a bit more but still have tension on the spring to be able to move the trigger back to the correct position.

Re: R700 trigger adj. problem with sear engagement

What makes the pin drop or not cock? Trigger screw or the sear engagement?

I mean if the pin is not cocking with forward force on the bolt and closing it, does that mean I need to back out the sear abatement screw or the trigger screw?

How about when the pin drops when I hit the barrel to a hard surface?

 

[WRENCHHEAD]

Re: R700 trigger adj. problem with sear engagement

the trigger screw, the same screw also resets the sear which is set up top/front of trigger.

basically with out tension because the factory spring is maxed out the sear is not engaging/ resetting properly and just letting the pin drop.

in order to make it work again you will need to tighten up the trigger screw again. so the spring actually has pressure on it so it can push the sear/trigger back into the right place it needs to be. from there you can adjust the sear engagement in the rear to take out the creep.

but only replacing the spring will you be able to properly adjust the pull weight and keep the trigger safe and reliable.

Re: R700 trigger adj. problem with sear engagement

also wanted to mention, every trigger is different. some don't need to replace the screw and some do to get the pull weight down. the reason for this is inconsistentcy in the factory springs.

i had to replace the one in my 700p, my sps functions fine adjusted with factory spring in it.

Re: R700 trigger adj. problem with sear engagement

I see...

I got it pretty good now, I'm just afraid the thing is gonna go off on it's own (and I'm sure it won't.)

Is that kit hard to install?

 

[WRENCHHEAD]

Re: R700 trigger adj. problem with sear engagement

pretty easy to install. just back out the hex set screw and take it out along with the factory spring, and drop in the new spring and replace the hex screw cap.

hell, i've taken apart the whole assembly and cleaned every before. it's pretty easy if you pay attention and note where every spring and part is oriented.

 

[taseal]

Re: R700 trigger adj. problem with sear engagement

I took out the screw but no spring came out (took it out to clean it) if I turn it so gravity and couple bangs will make it come out? How about that other spring Thingy? Where's that go?

I don't have to take out the trigger or disassemble right? Don't wanna do that. I can def replace that spring if it's easy as you say tho lol.

 

[WRENCHHEAD]

Re: R700 trigger adj. problem with sear engagement

take a thin paper clip and see it you can slowly pick it out. don't bang on it, the sear may move out of place.

the other spring loop looking thing is the bolt release spring, theres no need to mess/replace that. i just keep it my parts bin.

 

[taseal]

Re: R700 trigger adj. problem with sear engagement

I thought that's what that was... Why do they include that? The factory one breaks easy or something?

 

[taseal]

Re: R700 trigger adj. problem with sear engagement

Ok i ordered it. I hope it will make a better,safer and more consistent 2lb operation. I'm still not sure how it will, but I trust your wise judgement lol. It was only 12 bucks at brown ells and 17 with shipping

Re: R700 trigger adj. problem with sear engagement

expensive lil spring ain't it

Re: R700 trigger adj. problem with sear engagement

Saw a post here a little while back...said that the spring from a tire air valve fits and works well. Check and see. Fifty cents beats $11. JMHO

 

[taseal]

Re: R700 trigger adj. problem with sear engagement

fuck.... somethings not right

the screw didn't come out, and now I don't even see a screw....

I put the screws back in and now the trigger won't pull, and the sear won't drop the pin.

I know it wasn't gonna be easy as I thought it would...

great

I have two Rem triggers for sale, check my ad

Seriously, if you need one, I'll drop it in the mail tomorrow and you can mail payment when you have time. Triggers are serious business, be safe.

Re: R700 trigger adj. problem with sear engagement

Thanks to wnroscoe from here, we got it fixed! what an awesome person. he PM'd me, gave me his number, and walked me through taking the trigger out and finding the screw that fell in there and put it back together!!!

thanks bud, you rock!!!

 

[PCR]

Re: R700 trigger adj. problem with sear engagement

If the trigger return spring is bound up in the slot, no amount of adjustment will get you right and it can cause the problems you stated. Sounds like wnroscoe solved your problem. What did you find to be the problem?
