Love It
by Carmelo Romano -
Excellent quality for the price..perfect for a quick build
What’s not too like?
by Very nice Lower Receiver. Price point was outstanding. Which they made a matching upper. -
Outstanding billet lower. I wish they had a matching upper receiver…
Magwell too small
by Michael -
Will not accept Magpul or hexmags. Does accept D&H metal mgas, but will not allow BCG to lock back, even manually.

AR 15 stripped lower
by Mike -
Great fit and finish is clean. Threaded bolt catch was a nice added feature. Upper fit was nice and tight, did not need adjustment screw. Great value.
Buy when you can
by Geoff -
very well built and finished. Could not beat the price of$69.99 on sale. It will give Aero Precision a run for the money on their M$ receiver Only difference that I found was that rear detent pin hole for the spring was not threaded, but 30 seconds with a 4x40 tap fixed that.
17 Design Receiver
by Gary -
Easy assembly. Love not having to fool with pinning the trigger guard, and the bolt hold opening being treaded it great. Love this lower, want more and more and more.

Very nice lower, design is cool, i like the finish the media kinda looks brushed..details on the machining are great. So far im digging it.
Almost 4 stars

Ordered some receivers on sale and was initially happy with the fit and finish, however metal mags were exceptionally tight. I would have left a 4 star review for this but 17 Design reached out after I’d posted the issue on social media and they immediately set out to make it right and offered to open up the mag wells for me.

<br>The customer service at Primary Arms as well as at 17 Design make this a 5 star review from my perspective instead of a 4 star.
Well made, great price

I’ve owned several different AR lowers, all are forged. This lower is my first foray into billet. I like the sharp, clean edges of cnc machining vs the rounded appearance of forged. The 17 Design lower has minimal engraving without unnecessary frills. I was impressed with the tension adjustment screw, when tightened eliminates the annoying wobble sometimes present between upper and lower receivers by different manufacturers. My only complaint lies with the design at the bolt release. It’s a little thicker and won’t accommodate a magpul B.A.D. lever due to clearance interference. I’d could probably notch the lever arm but it’s not that imperative an add on. So far, I’m very happy with my purchase and recommend without reservation.
