PSA AR15/PA10 Enhanced Polished Trigger

We start with our standard single-stage government-style fire control group,  finely polish the contact surfaces and then coat the hammer and trigger in a super slick nickel finish.   The result is a trigger that is substantially smoother than mil-spec.  A great economical upgrade.

Is this a nickel boron or nickel teflon finish/treatment?
M R on Jul 14, 2018
BEST ANSWER: This FCG is Nickel Teflon coated, the mfgr. (Squared S casting marks, I won't give away who actually makes it) only offers Nickel Boron coating on their 2 stage FCG's.
Anyone have recommendation on manufacturer for lighter springs?
Clint on Jul 26, 2018
BEST ANSWER: JP springs enhanced reliability set. This is a stronger hammer spring for striking harder primers as seen in steel cased ammo. The trigger spring is lighter than mil spec.Be sure to purchase the correct set or you will have light primer strike problems with a lower power hammer spring.
Will this work in this?
Dave M on May 24, 2018
BEST ANSWER: It is included in that kit. EPT = enhanced polished trigger.
Does anyone know what the trigger pull weight is on this trigger roughly? I need a pull > 5.0 lbs to be within my department's patrol rifle policy.
Chris R on Feb 12, 2019
BEST ANSWER: With the standard hammer spring it will be at approx. 5 1/2 to 6 pounds. With a lower weight hammer spring the pull weight will come down. I have a couple of these as well as the BCM, ALG, and Right to Bear Arms, all with a nickel finish. All of them are quite a lot smoother than a mil-spec trigger.
So is this everything needed to build a complete trigger? Or is it only some of the parts and other parts are needed to complete the trigger assembly.
Howard D on Aug 31, 2018
BEST ANSWER: This IS the complete trigger assembly, and I must say that it is worth more than the price paid. It is a nice, smooth, grit-free action.
Will this kit work in the s&w mp 15-22?
Jerry D on May 25, 2018
BEST ANSWER: Yes it will. Same thing you have. Just better quality
Can the hammer and trigger be further polished without damaging the nickel coating?
Jay A on Sep 6, 2018
BEST ANSWER: I am sure you could as long as you do not remove too much material. It should slick up as it wears in. In my case it is working exactly as described without any further polishing.
Will this work with the Palmetto AR9 lower?
Terrance on Jun 25, 2018
BEST ANSWER: I put one in mine everything was identical side by side with the black mil-spec trigger this is a PSA ar9 pistol
One more time....Is this Trigger Stamped/Rollmarked with the Double " S " 's ....All of my older compete lowers with the EPT Trigger system was Stamped/Rollmarked with Double " S " 's ??? There is a reason I am asking.....Thanks
J. Michael on Dec 10, 2018
BEST ANSWER: Hello; trigger has a large “S” in a square on the left side and a “3” in a circle on the right side.
Hammer has two (2) large “S” in separate squares Diagonal to each other on the right side and the number five “5” in a circle on the left. Panja. Hope this helped.
Does this assembly come with complete instructions?
Jim K on May 25, 2019
BEST ANSWER: No but the information is readily available on the Internet or YouTube
What size are the pins? I understand there are 2 sizes.
James A on Feb 6, 2020
BEST ANSWER: This pin is .154 if you have any standard ar-15 or ar-10 lowers then this will fit fine. I have even put one in a sign mcx no issues. If you have a colt sporting rifle pin size is .171 and this wouldn't work.
Can you get this kit with the flat bow trigger ??
Dennis H on Nov 22, 2018
BEST ANSWER: No, that may be available as anotner part number - contact support for special orders.
Does this ept trigger set replace the trigger set in a colt bushmaster ar15?
Randy W on Jul 7, 2019
BEST ANSWER: It did in mine...
My new Ruger AR556 has a trigger pull of 8 lbs. With the JP Enterprises enhance reliability spring kit, will the EPT trigger reduce the pull to 5½ or 6 lbs?
Gary H on May 30, 2019
BEST ANSWER: EPT trigger and JP enhanced reliability springs have consistently come in at 3 lbs 8 oz to 3 lbs 12 oz for me.
Will a "trigger job" ("stoning to change sear profile") damage this trigger if done well? My gun smith is concerned about loosing the coating. At this point it is smooth with a clean break but close to 8#. He doesn't like lighter springs. I've shot his personal trigger and it is much lighter.
John F on Jun 22, 2019
BEST ANSWER: It breaks in with time. I would just take it out and enjoy it a bit. You'll lower the pull that way and have way more fun

Great bang for the buck
If comparing to a Geissele.....well, don't. This isn't a Geissele. But, it does offer a distinct improvement over a stock mil spec trigger, especially if slight lower rate springs are used. With a quality lower rate spring like JP one can get trigger pull down to around 5 lbs. Not a precise a reset as Geissele, but it also does not cost $200.

This is a great tigget. With JP springs it's an outstanding trigger for way under dope in tigget prices.

Excellent trigger pull and very reasonable price. Recommended for new builds or as a drop in upgrade for a bad factory trigger.

PSA enhanced polished trigger
I definitely recommend this enhanced polished trigger from PSA. The trigger pull is smooth, and doesn’t have that base mil spec trigger “stagey” feeling as you press it to the wall. You get less creep and a crisp break for minimal cost compared to other triggers.

Great Buy!
Easy to install and provides an easy smooth pull.
I was concerned that the trigger assembly would be cheaply made for the price. Turned out that the trigger assembly was well worth the price.

Very crisp with a short take up. You really can’t beat it for the price.
