Excellent value


Fits great. Ran great at the range. Color was slightly greyer than my Oly lower so keep that in mind.

very good product


Fits nicely to the lower I built for my current project. Primary Arms' service & shipping were excellent. Have quite a few more items to buy and a good number of them well come from Primary Arms as well. Thank you.

Great products.


For the money, I don't believe anyone makes a better upper or lower. My only problem, and it's a small one, is that fitment between the 2 could be better. Not that it is a deal breaker, but it's just a little sloppily than I would like. Other than that, standard lower parts work like a charm. Built 5 upper and lower sets, no issues except what I said above, and even with Colt uppers and lowers there's sometimes a little slop. Would definitely buy again.

solid but inexpensive


Good as any receiver I've ever used. No complaints at all.

great upper receiver


Good company to purchase from. Transaction was fast and easy. Article was received sooner than I expected. And was exactly as advertised. If I ever need to buy something, I will check here first.
