I have a 7.62 pistol.  It has a spikes lower parts kit in it with a wolf extra power hammer spring.  The trigger pull is pretty heavy.  I was having a problem with the firing pin hitting the primer but the round not going off.  Thats the reason for the wolf spring.  The wolf spring as well as a switch to wolf ammo took care of that problem.  I also have an extended firing pin but its not installed.  My question is, is there a trigger out there that is lighter that will still be able to send the round down range ? Geissele trigger would be nice but I'd prefer not to drop that kinda coin on a trigger upgrade.  I could spend that money on turning it into a SBR instead.

Lightweight hammer, sometimes called "speed hammer" might let you get by with a regular hammer spring even on those hard milsurp primers.

My blaster has a DIY trigger job that gives me a 4# pull using stock springs. I "enhanced" my firing pin myself and I have no problems with any of the ammo I have tried.

Never had a problem with a normal lpk and Tula amp in my 12.5" 762x39

My 2 ,7.62x39 Carbines run the enhanced firing pin. Neither uses extra power springs. Both are YHM , one is running a RRA 2 stage  the other a simple milspec , They eat nothing except cheap stuff, and in the 4k plus rounds I have never had a failure to ignite.

This is the ticket - instead of increasing the spring's power, you should try an "enhanced" firing pin. I don't know if they are longer overall, but the narrowed down tip that goes through the hole in the bolt is ever so slightly longer than standard AR firing pins. There are a few of them out there. Mine are from PSA.

This is what I do on my 2,
but I use REDX Arms extended firing pins,
standard trigger groups and springs and shoot nothing but steel case ammo.

Same as above here, about 900rds through one gun. Enhanced firing pin fixed the occasional FTF.

Maybe the Hiperfire 24E, there was an earlier thread on aftermarket triggers and their hammer force in lbs and one of the Hiperfire's was significantly higher in force than the rest, including a GI trigger.
Downside is it's not cheap, I can't justify dropping $250 on a trigger to shoot cheap ammo out of a budget build gun.

Personally I start with an enhanced firing pin, if I'm still having ignition issues then the Wollf xtra power spring is next.

Anyone tried a two stage trigger with an xtra power spring? One of my 7.62x39 builds runs a GI single stage and with surplus Yugo will occasionally fail (like once out of 50). Dropped an xtra power spring in which runs 100% but I hate the pull. Been thinking of swapping in a two stage RRA I have in another rifle to see if that will make the xtra power spring easier to live with.

Buddy bought a PSA upper that was supposed to have an enhanced pin in it.  He had no end of problems, then figured out they put a regular pin in the BCG.  He replace the firing pin with an 'enhanced' one and it's running like a swiss watch.  My 7.62x39 w/ enhanced pin (with C-Prod mags) ran perfect out of the box.

So you guys think I should swap out the extra power hammer spring and put the other one back in and use the extended firing pin instead?  I didnt get to shoot many rounds with the ''stock'' hammer spring in there but dont remember much of a difference in pull the gun had.  I'd spend around 100 bucks or so on a trigger if it was nice enough.

I would just ininstall the extended firing pin and leave everything else.
Redx arms was $10 shipped in just a few days

Might want to tweak the title...  It says 7.62x36.  Never heard of that critter!

Com Bloc 7.62 ammo is notorious for hard primers (in everything, not just this round), and it usually helps to go up in hammer spring weight.  You can do this with a quality aftermarket hammer like the ALG QMS or ACT and won't have to worry about the notorious grit and crappy feel of a "standard" AR trigger group.  Yes, your Wolff spring will work with either one.

My bad on the thread title it should be fixed.  

Has anyone tried the hiperfire stuff like the enhanced duty trigger?

Hiperfire EDT with red spring is what I used on mine for awhile.



Armalite used to sell a 7.62x39 two stage with a higher mass hammer for $67.  You might call them and try to order it direct.




Hiperfire has a new version of the EDT that is supposed to work with either spring.

How'd you like the hiperfire?  Why did you switch and what did you switch to?

The hiperfire is pretty good for it's price.  I pulled it out of that lower to run a franklin binary trigger.  The binary trigger won't run 7.62x39 though, so it's got a 5.56 upper on it at the moment.  I'm going to try the fostech echo trigger as it uses some hiperfire tech for extra power and I'm hoping it will work better with 7.62x39.  In the mean time, the 7.62x39 is sitting on a spare pistol lower and I dropped a spare MBT in it.  I haven't shot it with the MBT yet, but I expect it will work fine.  If not I'll try the Brownells B-GRF (a cheaper version of the SD3G).  If neither of those work I'll probably pick one of the two and put a wolff XP spring on it.

So I carried the AR to the range today.  I swapped back in the stock spikes lpk hammer spring and swapped in the extended firing pin.  Same results as I was getting when I first put the gun together.  I get a primer strike but no bang.  I only pulled the trigger three times because I didnt want to keep wasting ammo.  Two out of the three failed to go off.  I tried different ammo as well.  So it looks like my gun needs the extra power hammer spring to work.  So I guess the question is still is there a lighter trigger pull with the extra power hammer spring?  The couple times today I did pull the trigger it did feel a little lighter but if it doesnt work it doesnt much matter.

I swapped a RRA two stage trigger & Wolff xtra power hammer spring in my 7.62x39 rifle, gotta say the trigger pull seemed to barely increase on the 2 stage going from stock springs to the xtra power hammer spring. Compare that to the trigger pull almost doubling with a single stage & xtra power spring.

I think RRA has their 2 stage for $85 right now which is about as cheap as you can find it anywhere else.
Did a quick search for Armalite and the few hits I got on their 2 stage non-adjustable trigger were about $95.
Even a Del Ton 2 stage is around $100.

I use an ALG ACT kit in my AR-47 and its never let me down.

The ACT plus the proper enhanced firing pin have ensured that I have not had a single light strike or fail-to-fire in 3K+ rounds.
