Dennis J on Jun 4, 2019
BEST ANSWER: These are gteat prices, or just get the drop in with all the upgrades done to it an comes with the new pins. 3mins an ya done an ready to shoot. Got a 2lb or less on my ar15 an i love it. Smooth an clean brake when pulled
Is the trigger spring lighter than mil-spec and hammer standard weight or are both mil-spec weight?
David S on Jul 4, 2019
BEST ANSWER: The red spring is heaver than mil spec. If you swap it out for JP yellow or KVP blue trigger spring you get a 4lbs trigger pull. The hammer spring does nothing towards the pull leave it be.
Are the hammer and trigger springs standard milspec weight or are they similar to the JP enhanced reliability 3.5T spring set? They are colored like the JP springs.

will this trigger work with a PSA .224 Valkrie and Lower? Its the Complete PSA AR-15 Mil-Spec lower and i recently received my .224Valkrie PSA Complete upper.Was looking at a better trigger for it now?lol
bigmike on May 28, 2019
BEST ANSWER: Yes it will work. This will work in a .308 lower also.
So go for it, it’s a nice trigger. Just FYI they don’t come with trigger or hammer pins. So you’ll need those. The psa anti walk pins are EXCELLENT, and only 9.99 + shipping.
What weight of pull are you getting with these?
Brian C on Jun 9, 2019
BEST ANSWER: The specs (see above) say:
First Stage Weight: 2.0lbs
Second Stage Weight: 2.5lbs
Total Pull Weight: 4.5lbs
Looking for a good trigger for a Palmetto AR-10 Noticed that my installed RISE trigger has an issue with some military primers. This rifle is a duty/27-7/SHTF rifle and needs 100% reliability. Is this one capable?
H S on Jun 29, 2019
BEST ANSWER: I'll answer my own question. This trigger set will reliably set off hard military large rifle primers. Is a great trigger tooo.
Will this work on the PSA AR47 lower that takes AK mags?
Thomas T on Jun 5, 2019
BEST ANSWER: Actually, it should work for the KS 47. The KS 47 uses an AR15 fire control group. The KS series do not use the 1 pc. self contained, drop in fire control groups.
Difference between this one and SKU: 516447205?
Joshua G on May 31, 2019
BEST ANSWER: One SKU does 'Not Include Hammer & Trigger Pins' , while this SKU 'Includes Trigger/Hammer Pins Included x (2)'.
What is the weight of this trigger component?
D J on Jun 18, 2019
Will this work with a blowback PCC?
John K on Jun 9, 2019
BEST ANSWER: I’m pretty sure if your pic lower is said to work with standouts Mil-Spec trigger this should work.
Will this work in a PSA AR-9?
Robert H on Aug 5, 2019
BEST ANSWER: Not, sure. Mine are in 556 & 300 BLK. Your BCG type makes a difference, with the hammer contact.
Try it, if it doesn't's an omen to build another one !!
Is the hammer and trigger made from S7 or another type of tool steel?
Everett on Aug 4, 2019
BEST ANSWER: I’m not an expert on types of steel. I just know that I did a polish job on the trigger and it’s a smooth and crisp 4.5 pound trigger

PSA is a great place to buy quality products at a great price. Installed trigger in PSA AR-10 yesterday. Trigger pull is much better than stock. Crisp and clean break. Only shooting will tell ... that will need to wait until the weather clears.

Smooth Trigger
This trigger made my AR-15 into a nail driving machine! You can spend more but for my money this trigger assembly will answer my need for an upgraded trigger assembly.

Great trigger for medium to short range work.
I have purchased 3 of these and have 2 of them in my ar pistols. I own several top end triggers and prefer these for shooting out to 100 yards.
