AR10 trigger advice

[DirtRacer151]

This is not a question asking the best ar15 trigger as i know its been covered a million times. Im looking for a trigger for my POF 308. I plan on using this rifle for mostly bench/bi pod work for precision shots. Even though i will be mostly shooting hand loads from it i would like it to be able to shoot mil surp as well just in case i was in a pinch some day. I know that a lot of match triggers being so light might fail to ignite some harder mil surp primers and that is why some trigger manufactures are developing ar10 specific triggers w/ heavy hammers and springs. I would really like a Timney but the ar10 version is only in 4lb pull. Im looking for something around 2lbs or less with enough "umph" to work with anything i throw at it. Any ideas? Heres some pics of daddy and baby just for fun

I've got a 2-Stage RRA trigger in my POF that I like. But it isn't adjustable, which is what sounds like would be better for you.

I've heard a lot of good things about the Geissele trigger. I've also heard some good things about the AR-Gold trigger, but not as much as the Geissele. Both are adjustable.

yeah but will the geissele match trigger set at 2lbs get it done with those hard primers? This is my biggest concern. I need a light trigger that will be reliable with "any" ammo for 308. If one exists that is

I've shot hand-loads, factory (FGMM-168's) and M118LR with a jewell trigger that was set pretty light (<2 lbs) and never had a problem striking (and detonating) the primers. But that's with a bolt-gun; don't know if a gas-gun would run different with a lighter trigger. That's why I'd suggest an adjustable.

On the other hand, the weight of the trigger-pull shouldn't affect how hard the firing pin hits the primer, should it? Maybe I'm wrong, but shouldn't it only affect the amount it takes to break the trigger?

[DirtRacer151]

I think you are right but i know timney designed their ar10 trigger to have a heavier hammer and stiffer spring just for the ar-10 aplication. The adjustable part doesn't have much to do with how hard the hammer hits. The geissele and jewels seems to be the most popular for ar15s but they dont say anything about working with 308 too. I guess im attracted to the timney because i know it was designed with 308 in mind but its just to darn stiff

Just for fun, I did a search over at The Sniper's Hide on "AR10 Trigger" and came up with this thread. One guy made the same point you did (towards the bottom of the thread) about AR10-specific triggers and light primer-strikes. They've got some pretty knowledgeable shooters over there, so there's probably some good info to be had.

Edit: By the way, can I ask what type of mount that is over the top of the scope on your POF?

[DirtRacer151]

those are a.r.m.s #22 rings with the ring cap and ring cap rail. Its all on the a.r.m.s website. Thanks for the link ... im off to go study!!

Thanks for the info ... good luck on your search!

I have the geissele DMR trigger on my ar-10. It works fine, second stage is between 0.5-1.5 pounds. Shot port surplus, south african surplus, fgmm, hornady TAP, walmart crap.

Haven't had light primer strikes yet. Trigger is focking sweet. Worth every penny, find the DMR model.

Wow that is one sweet rifle. How does it group? I have a Timney 3.5 (maybe 3)lb trigger in my Fulton Titan lower and have never had problems with SA or Australian milsurp. I really doubt you will have any primer striking issues with a light trigger.

[DirtRacer151]

i have not shot it yet.. still waiting on a trigger decision, 308 buffer and spring, and i need some higher scope rings. Are you sure you dont have the 4lb timney? Thats all they show on their website for ar10s

trigger break weight/tension does not necessarily have anything to do with hammer strike force.
you can't go wrong w/ a geissele, timney is good too.

the only thing ive found wrong with the geissele is the price tag lol. The only thing wrong with the timney is the 4lb pull is to stiff for my liking. Im stuck...ahhhh

Out of sheer supply & demand - as in it's the only one I can find for a decent price now - I'm giving the Jard nonadjustable a try. The weight of trigger pull is determined by the weight of the trigger return spring, so a 1.5 lb or a 4 lb uses the same hammer spring. Might be worth a look. I bought their adjustable version a year or so ago, just couldn't get the damn thing set up properly.

I've heard the Timney is hit or miss also.

I have a RRA 2 stage on my POF/DMPS 308 and all my other ARs, have to say that for $88.00 it was I think about the best deal out there.

I had a Jard adjustable in my ar15 too... biggest POS ever! I couldn't get mine to run good either so i sold it. Let me know how the non adj is. The jard looked so promising back then
