Two different uppers with the same problem.

by

Had to send the first one I got back for an exchange due to the upper receiver not allowing magazines to fully seat in the lower (the problem followed when trying this upperon different lowers). Got my replacement and it had the same issue as the first with the addition of the pin holes being ever so slightly off. I wound up picking up an Anderson stripped upper from a local shop and swapped the barrel, forward assist and rail onto it. I think Radical needs to look at their QC process a bit closer.

Great

Extremely fast shipping. Nice fit and finish and runs out great. Hella good buy.

Fit and finish

by -

I just switched from the 10.5" 300 blk out with the moe rail to this one. The fit and finish of the primary arms exclusive m-lok rail is much, much nicer than the moe version. It really streamlines the profile. Will report back after shooting it

Outstanding Service, Good Product

What a deal. Got this in the mail today and my initial inspection and reaction were excellent. Well made, solid, well packaged, free of dents, blemishes, and imperfections. For the price you can't ask for more. This is an excellent buy for the financially responsible gun enthusiasts. I'm sure it will perform well at the range.

<br>Where Primary Arms gained 5 Stars (I'd give them 10 if I could) was in customer service. I ordered this Sept 12th, they processed, packaged, and shipped it the same day. It was at my front door Sept 14th despite them being in Houston (Hurricane Harvey) and me being in Orlando (Hurricane Irma). THAT speaks volumes of a company. Primary Arms is now my go to dealer for all things guns. You can't go wrong with this company.

<br>Thanks folks.
