Will this kit fit well with the 5d tactical milled lower??
zouzou on Jun 4, 2020
BEST ANSWER: The 5D lower would be a 80 that is finished by the customer on a 5D jig. I build mine on a Palmetto State Armory mil-spec lower and it runs FLAWLESSLY! Don't worry about PSA quality, because its TOP NOTCH! ALL my PSA weapons run like a watch. ZERO ISSUES. You will be fine with your 5D lower.

Nice Kit
This is my 1st PSA kit (and first pistol build) and I'm happy with the fit and finish as well as the components used. Also appreciate the fact that an extra spring and detent were included considering how easy it can be to lose one of those while assembling a lower.

Have yet to fire as I've been very busy but looking forward to seeing how she feeds and groups. Will try to remember to follow up on this review once a few hundred rounds have gone thru.

Great fun pistol.
My first time building my own. Super simple. Took about an hour. Ran it at the range. Zeroed at 50yds. Runs great.
Got Hexmags to match the FDE cuz Pmags out of stock everywhere in that color. They didn’t run more than 25% of the time. But my Pmags ran no problem. Determined it was the mags not the build.

Nice little shooter!
I am pleased with this pistol kit from PSA. It appears to have quality parts and was a breeze to assemble. It shoots smooth and I haven't had any hiccups whatsoever. I am waiting for my Sig Romeo 5 in FDE to compliment the rig and am looking forward to putting many rounds through this.
