Will this trigger fit/work without interference on the low serial number PSA PA10 lowers? Geissele two stage triggers have to be modified.
Thomas S on Jul 6, 2018
BEST ANSWER: I have a gen2 PSA ar10 lower and it fit just fine. The two seating pins were a bit tight and I called customer support and confirmed the fit so I was able to make it fit with no modification and it works just fine.
why did you not post my review?

OMG, I've never been so triggered!
My new PSA 2 Stage trigger showed up today. I stopped work for 15 minutes to install it in my 18" AR15. I've never used 'high end' expensive triggers so I cannot compare to those. However, I do have standard mil spec and the PSA Enhanced Polished Trigger (which is awesome for $30). This PSA 2 stage is really smooth and the pull is so very minimal. While sighting out my backdoor at nearly 100 yards I did not see any side pull in the scope due to the trigger like I was seeing before. I can't wait to take it out and shoot.

Price is Great for the Performance of this Trigger
Trigger is a great replacement for the mil-spec triggers in kits. While not the best trigger out there, for the price point it is great. The first stage was a bit rough at first, but smoothed out quickly. The second stage had a nice clean break. I immediately saw better grouping than with a standard mil-spec trigger. I would suggest this over a more expensive trigger unless you are shooting competitively or have spare money to spend.
Installed in a new lower.

Good combat trigger.
I have only my Giessele to compare but I wanted to give PSA a try. Nice intuitively tactical first stage. Followed by a hair of creep and crisp enough break. Feels more like a “roll” than a “break.” But I’m happy with it. I would say that with names like Giessele and Larue and Timney, and CMC, this trigger performs as anticipated.

A little less performance, A lot more value !!
To be totally honest, I purchased this trigger for a PA-65 build as a way to save money until I could get a “better” trigger. I have an SSA-E in an SBR build I’d done earlier and fully intended to put one in this build once I had the extra cash. I took a chance on this PSA 2-stage thinking that if i didn't like it, I could use it as a backup or in a future build. Once I got it into the rifle, my first thoughts were its nothing special. I am happy to say that after a couple trips to the range and some dry fire with dummy rounds this trigger has smoothed out to the point I'm starting to love it. It's NOT a “G” trigger, BUT, it has a very short take up, a nice break and a short reset. It had a little grittiness to the pull at first but has smoothed out nicely and seems to get better after each use. I know this trigger is not for everyone, if you want the very best and have the cash, then get the best. However, if you’re willing to take a little less performance for a lot more value, then this PSA 2 stage is worth a look at the very least!

I think I would rather have the Palmetto enhanced TA with a JP spring kit. it feels a lot smoother.

Worth every penny!
I have one of these in my PSA 224 Valkyrie and it awesome. I just bought another to put into my PSA 6.5 Creedmoor build. Can't wait to test it out.

Needed a bit of break in!
Bought my trigger installed it and was not real happy with the first stage at first (it was rough / gritty). The second stage of the trigger is and was fantastic (crisp and clean) after each trip (two or three)to the range it has seamed to have broken in and is the trigger I was hoping for smooth on the first stage, and crisp on the second stage.

Good bang for the buck
I purchased the PSA STR lower equipped with this trigger assembly and Shockwave lower (trigger assy added later) for my personal rifle and pistol set and am very pleased when comparing to most other fire control groups I have used, especially when comparing to an off the line standard 7-9 lb pull set-up. The 1st stage is a smooth take-up with a clean, crisp break to fire at the 2nd stage. I did not notice any creep at the 2nd stage. I haven't checked the pull with a gauge yet, but am going to in the near future to see if pistol and rifle set match. It's too light a pull to tell without a gauge. I plan to purchase more of these trigger assemblies in time for use at one of the levels of manufacture of D.A. Wolfe Arms, LLC TAC3-15 rifles and pistols.
