I built (assembled) another 5.45x39mm precision rifle recently. I am currently using an ACOG scope. I took itto the range yesterday for its maiden voyage and was quite happy to see it is capable of good accuracy. Withe a cold barrel it shoots 1.30" to 2.0" at 100 yards. This is wth a S&W chrome lined barrel that's now free floated. Bear in mind I have many thousands of rounds of Russia 7N6 ammo. That is all this rifle will ever see.

I was stretched to my limit shooting decent groups using a military grade "combat" trigger/hammer with orange heavy hammer spring.

What I'm asking here is this: if I purchase a Geissele SSA-E two stage trigger/hammer for this rifle will it have trouble igniting these hard Russia primers?

Anyone out there with first hand knowledge that can give me their experience as it relates to ignition & 7N6?

Thanks for any help. I'd rather not spend $240.00 just to find out it can't pop a Russia primer reliably.

All my GA triggers have run all my 5.45 uppers. You'll be good to go.

 

I've never tried shooting 5.45. However I will say my Geissele SSA-E's hammer has a noticeably heavier hammer spring than my mil spec triggers.

They have worked flawlessly for me

I shoot a lot of 7n6 through guns with the G triggers.  No issues.

I use an SSA-E in my 10.5" 5.45 SBR and haven't had any issues.

Let's build the nicest AR that money can buy and then feed it the cheapest ammo.  
What could go wrong?

Thanks for all the excellent answers. It's appreciated.

Nothing in my personal experiences.

 

Alright I apologize. Fire away with the 7n6.

The only thing I can add regarding accuracy is this rifle is an honest 2moa gun firing 7N6. I know this because I fired it a second time today and it will put 5 rounds in 2" @ 100 yds (ACOG) when I do everything right. I have fired almost 700 rounds in the two range sessions since it's completion on Friday. I just wanted something cheap to fire large amounts of ammo at our 300 and 500 yard steel targets at our gun club. I was tired of spending so much money on .223/5.56mm ammo and reloading components since all I wanted to do was bang steel. The 2moa comes only with much concentration and trigger control as it's in the 7 pound range with the ".mil" trigger combined with that heavy orange hammer spring.

After discussing this topic with the forum and getting reassurance that Geissele triggers will indeed pop hard Russia primers I've decided to purchase the SSA-E. I prefer two stage so this ought to work out. Thanks for all of your positive comments,I appreciate it.
