Solid build

by

Extreme precision and quality craftsmanship. Made in my home state in Oklahoma. Highly recommended!

Tremendous Value!

by -

Well built and designed lower, would be a great value at a much higher price. It’s just the thing I needed to build my long range rifle. Highly recommend.

Excellent lower receiver for the price

by -

I assembled AR15 with 17 Design Billet lower receiver and was surprised how Palmetto Armory's upper receiver and it's lover receiver parts matched all lower receiver dimensions. Assembly was easy, and first test shows very reliable work with good target results.

17 Design Billet lower

This a very nice billet lower.Lines were all crisp and clean, mil-spec parts slipped right in. Very nicely made, will very much buy more when the panic buying ends.

Great lightweight AR lower

Great AR lower, super lightweight and fits any AR upper like a glove.
<br>Thank you Pimary Arms

Solid Billet Lower

by

$130 for a billet lower?? Why so cheap??
<br>Took a chance and bought it without much info available on it. It locks up to all my BCM and Aero uppers nice and tight. Screw in bolt catch and tension set screw (it's there, just didn't need it). No visible machine marks, smooth finish and everything seems to be in spec. There's no safety Select stops which threw me off at first but it aids in the appearance of it. Luckily these are always in stock so if I decide I NEED another lower I can pick one up.

Great billet lower for the price!

Couldn't be more pleased with this lower. Can't beat the price for a billet lower, I will be ordering more!

Nice Billet Lower

by

Nicely machined. Nice finish. Low price point for a billet lower. Married nicely to an Aero Upper; no need to adjust the lower tension screw. A threaded bolt catch with a set screw eliminates the need to tap in a roll pin. Suggest using an enhanced magazine release button due to the extra wall thickness of this billet lower. Other websites indicated some QC issues that apparently have been worked out.

17 Design Billet - nice, very nice

by -

These are very nice lowers, I’ve put dozens of lowers together from all different manufacturers. Got to say, the threaded bolt release pin is a great idea. The rest went together without any issues. Finish is nice too. Scores a 10 out of 10 for me.

Excellent lower. Worth the cost.

This lower is Excellent. Precisely made, high quality, everything in spec. AND the only lower I found with a nicely flared mag well, integral trigger guard (oversize for gloved hands) and and a captive bolt catch pin - no tiny roll pins to pound in.
<br>
<br>Built a DMR with an 18" 1/8 HB upper, quality parts kit and match trigger. The upper fit precisely with zero daylight and no play. Thx for the stimulus check, new administration. Putting it to good use!
