What's the difference between this trigger and a polished one?
Chadb115 on Dec 4, 2018
BEST ANSWER: An EPT is a single stage, mil-spec trigger that has been polished. It is still going to break at approximately 7 lbs albeit more smoothly. THIS is a Two Stage trigger, coated with NiB, with a 2.5lb 1st Stage and a 2.0lb 2nd Stage.
What else is needed for 9mm upper ?
Geno Y on Jan 12, 2019
BEST ANSWER: Get the Endomag if you're planning to convert this to 9mm.
This states no magazine. Does it have the capabilities for a mag with release or it is single load or fixed mag?
Tj N on Nov 4, 2018
BEST ANSWER: Just as it states, no gun magazine is included due to the different magazine capacity restrictions of different states. Easier for PSA to offer a complete lower and you buy the size you need that is legal in your state, than offer several with different size magazines which is a legal nightmare, unless you live in California that required a fixed limited magazine which is just one of the reasons it says can't be shipped to CA.. So any 5rd to 40rd to drum magazine will fit and comes with a mag release as shown in picture.
Does this come in rifle length too?
claude s on Feb 4, 2019
BEST ANSWER: No. you would have to purchase a rifle length tube, rifle buffer and spring to completely change it over. OR.... You could just shoot a rifle length gas system upper from your carbine length lower, possibly change buffers and be satisfied.....
Would this lower work as is, with a 458 socom upper? Or would it need a stiffer buffer spring?
Torrey W on Jan 13, 2019
BEST ANSWER: It will work like it is. Mine went on a 450 bushmaster upper it works fine.
Since it says multi caliber does that mean I can use a 308 or 300 upper??
Jorge A on Nov 4, 2018
BEST ANSWER: 300blk out: yes, that works on this AR15 platform.
308: no, that would require an AR10 platform
This says it’s a standard carbine buffer. Will it properly function with a 6.5mm Grendel upper?
Kent L on Nov 23, 2018
BEST ANSWER: Yes it will function on a 6.5 grendel. Thr above answer must have confused grendel and creedmore
Is this a complete lower?
VIdal on Jan 16, 2020
BEST ANSWER: Yes, all you have to do is attach your upper to it. And it’s ready to go
Does this lower accept pmags and magpul mags ?? 30 round as well as 42 ??
hollywood on Mar 18, 2019
BEST ANSWER: Accepts all 30 round mags I have put into it. Hex mags are sticky as usual. 10, 15 round mags have also cycled fine. Cannot speak to a 42 round mags.
Is the trigger guard removable?
Jon P on Aug 1, 2018
BEST ANSWER: Yes my psa moe lower has a removable trigger guard
Will this lower assembly work with a 7.62x39 upper?
jking on Jul 8, 2019
BEST ANSWER: Absolutely, I actually have a 7.62x39 on mine. These lowers will work on all standard AR15 uppers. Very solid.
Is the buffer engraved with the PAS logo? TY
andy b on Dec 20, 2019
BEST ANSWER: No mine came with nothing on it
I see that it says multi caliber . What are all the caliber uppers or just caliber size would work with this lower?
Robert C on May 18, 2019

As such, this Lower Receiver may be used with many Mil-Spec Uppers utilizing any number of calibers. These include .223, .223 Wylde, .224 Valkyrie, 300 AAC/300 BLK, 5.56mm, 6.5 Grendel, 6.8 SPC, .450, .458, 7.62X39, 9mm, even .22LR. Likely some others I have missed or forgotten. The lower, in most cases, does not determine the caliber.

It (the lower) will preclude many calibers (.308, 7.62X51, 6.5 Creedmoor, .338 Lapua, etc.) that do not allow the magazines to physically enter the mag well or that require a physically larger upper receiver to accommodate the breech/barrel of more powerful rounds.
Can the safety be switched to an ambidextrous safety?
Jack E on Jan 14, 2019
BEST ANSWER: Yes, just like any normal AR15 lower you can remove the safety that's currently installed and put in an ambitious safety as well as 45 degree throw one. I easily did it with mine and paid 17 for the short throw ambi safety.
Will this work for my 300 blackout upper I purchased through PSA as well?
Justyn D on Aug 22, 2018
BEST ANSWER: Yes. Just be sure the barrel on your 300BO is of legal length...
Any problem putting a 7.62 X 39 upper on this lower or does it need some mods to the buffer?
Eddy L on Jan 26, 2020
BEST ANSWER: This lower is not meant for 7.62x39. If you were firing 300 Blackout that would be another story. You’ll need to purchase a lower that’s meant for your round.
will this work with a 6.8SPC upper?
Jean R on Sep 10, 2019
Will this ship to California?
Jose L on Jul 10, 2019
BEST ANSWER: Straight from the Ad.


Due to state laws, this item cannot ship to California.

Does ANYBODY still READ, anything, before asking questions???
What is the trigger pull weight?
Christopher S on Apr 17, 2019
BEST ANSWER: PSA 2 Stage triggers I have seen advertised as well as the one I purchased all stated 4.5 Lbs total pull weight. 2.5 1st Stage, 2.0 2nd Stage.
Is this compatible with a Sig 516 upper requiring a carbine length receiver extension and telescoping buttstock?
Chris P on Apr 13, 2019
BEST ANSWER: ONLY if your SIG is mil-spec
Is this considered an other or rifle?
Viking on Apr 6, 2019
I just bought the .224 compleat gun with the two stage trigger !! What brand are the triggers and pull weights !! And anything a person can do to lighten the pull weight?
Shannon W on Jan 16, 2019
BEST ANSWER: PSA Brand. A lighter trigger spring might be available.
Can this be used to build an AR pistol?
Dennis S on Nov 26, 2018
BEST ANSWER: Always check local laws, generally you can turn a rifle into a pistol, but not a pistol into a rifle.
Will this work with a rifle length gas tube upper?
S Y on Jan 6, 2020
Is the receiver extension (buffer tube) 7075 aluminum? It just says it’s Mil-spec diameter but doesn’t mention the material it’s made from.

Nice, crisp trigger - assembled well
The whole lower was assembled perfectly and came well lubricated. Very nice trigger, I don't see myself having to replace it anytime soon. It's very crisp with a very small uptake and a clean, light break for the 2nd stage, probably close to 4 lbs. I like the magpul grip and even the base magpul MOE stock is better than a classic one, still it can use an upgrade (i'm personally getting a magpul ACS-L) I've shot about 400 rounds of 5.56 and 400 .223 out of it and it has performed flawlessly.

Amazing bang for the buck!!!
Very nice lower. Great MOE furniture. Finish is even an nice. Two stage trigger is perfect. Super smooth 1st stage at 2 Lbs, clean break at a consistent touch over 4 Lbs. So worth the money spent, would not hesitate to buy again.
February 10, 2019
good function , good trigger
lower functions properly. trigger is much better than most ar triggers . generally the first thing I do on any new firearm is to replace or modify the trigger . I can run this trigger as it is .

Well-done piece of equipment...
Everything nice and tight. Sweet that it arrives already having the enlarged trigger guard. Nickel-boron trigger gets to first position at two pounds; trips at four and a half. Dimpled takedown pins. Price has dropped $20 since I ordered. Wait long enough, and PSA might just give them away...
