Bill V on Sep 6, 2019
BEST ANSWER: While in the Greenville retail store today I was told that the triggers are silver colored as is the hammer, Apparently they (PSA) have changed how/what they do regarding EPT's.
when i bought my first gun from a store they did the FFL paperwork for me. Since i am gonna buy this lower assembly online, do i need personally apply for FFL in a gun store or i don't need to worry about it and just fill the form and PSA will do that for me?
D R on Dec 27, 2019
BEST ANSWER: No, you dont need to have a ffl. It can be shipped to a ffl in your area, where they will transfer to you when you go to pick it up. You should be able to pull a list of ffl carriers in your area on line.

Buy without worry or regret.
The MOE EPT SBA4 complete lower is perfect to complete an AR 300blk pistol build.
Fit and finish as good if not better than my Daniel Defence rifle lower.
The enhanced polished trigger (adds $30 to price over milspec trigger) absolutely perfect trigger weight and break for me, with no need for $200+ price/legal liability of aftermarket add on trigger group.
MOE grip can be used to store small items such as lithium 123 and cr2032 batteries.
SBA4 (official approval letter from ATF) pistol brace also perfect for me. Adjustable, more sturdy and comfortable than SBA3 or (shudder) Shockwave brace.
I wanted shortest practical barrel.
PSA only one to offer 8" cold hammer forged chrome lined barreled upper assembly in 300 blk.
1/8 twist provides recommended complete Revolution in 8", which is also minimum recommended length barrel for most suppressors.
I am only shooting supersonic rounds, so I followed another manufacturer's tuning advise and substituted an H3 buffer instead of stock carbine buffer.
Cycled mildly and flawlessly from first shot to last with 110, 125, and 150gr 300blk ammo.
PSA ships fast, has good QC, and excellent parts already assembled @ same price as if I built it all.
Email reply slow, but phone customer service agents very pleasant and helpful.
Only thing I could wish better is free shipping on everything.
Great price, great quality, fast shipping.
I am satisfied with no regrets.
