Excellent Product

by

Made in USofA heartland. Assembled with milspec lower kit...everything runs smoothly. Married to a 16" side charging upper and all runs perfectly. Buy several before they're outlawed.

Impressive affordable lower

by -

Finished assembling a pistol build with this lower and I'm impressed by how tightly everything fits together. All holes are in spec and it has the threaded take-up screw hole under the grip to really tighten things up (screw wasn't included with mine but I had a spare.) Magwell flare looks great and finish is clean. I'll definitely buy another.

Very well made

by

Picked one up recently, looks well made.

Will be looking for more

I bought this purely because it was the cheapest lower Primary Arms had in stock, but I will seek out 17 Design in the future. Beyond a basic stripped lower, this has a rear set screw for properly tensioning your rear takedown pin and they are made in Oklahoma City! Very happy with this lower.

Quality lower

by -

This lower was machined very well and was easily assembled. The only reason it’s four stars is cosmetic appearances, it’s finish is just a little bit off from normal black anodizing.

Quality!

by

This company is local to me and as a supporter of local businesses I purchased this lower. The overall finish is great! Did not have any issues putting it together and shot flawlessly when taken to the range. I have since purchased two more lowers and look forward to more products.

Not perfect, but a good deal in 2021

by

I can’t remember if I already reviewed this, but I just finished a build with this lower and CMMG parts, all the parts fit well in the lower, only downside of this lower were some tool marks in the trigger pocket. Other than that it’s great. Will buy again.

Best stripped lower I have used

by

Well made, and when assembling it, did not need to ream out the holes for pins to go in. Everything fit perfectly. Only one I have used that fit so well.

Absolutely hands down is an absolute top notch military spec lower receiver fit and finish work perfect which is more than I could say for some lowers that I purchased that were twice the money you can't go wrong with this lower awesome!!!!

Nice Forged Lower

by

I have already reviewed the 17 Design billet lower with an integrated trigger guard. That review for fit and finish applies here, although one of 3 forged lowers did have slight machining indentations that should have been caught by QC as a blem. But, no big deal. Differences with the forged lower are no set screw for the bolt catch lever and no integrated trigger guard, although the latter is a nominal cost fix with a polymer trigger guard that still makes this stripped lower a very good competitive price point. <br>If one is ambitious enough to thread the channel for the takedown pin (where the takedown detent and spring go), here is an excellent video to do just that (no affiliation): <br>https://www.youtube.com/watch?v=dQUezyWxbq4<br>The tap wrench that I use is a Starrett T-Handle Model 93A along with an Irwin/Hanson 4-40NC tap set and a cutting oil. <br>One of these days I hope to try the 17 Design lower with an integrated folding stock feature. Forward thinking indeed by 17 Design.
