ENJOYING THE NEW COLORS!!!

Just finished another one of my many Sota Arms Builds!!!!! Gene 4-18-22

I just wanted to say that we have been buying Sota Arms lowers and uppers, parts for quite a few years now, and we have experienced Zero problems with Sota products, and will always recommend you guys to our fellow shooting sports friends. Keep up the good work. Regards, Brad and Kathy 5-3-22

​We went prairie dog hunting this weekend with the new 20" ss ar barrel and put over 1200 rounds thru it and it worked wonderfully. Thanks again for a great product.-Broc V. 5-30-22

DEDICATION

I had the pleasure of buying several parts from SOTA. By far my favorite was their promotion that allowed me to dedicate an AR lower to my dad. So cool. Great service and quality products. Jean A. 7-25-22

Best Looking

I have bought several lowers and uppers from Sota over the years and never had any issues. The lowers are unique and one of the best looking and functioning lowers available anywhere at any price! Tom S. 7-27-22

​I lived a few blocks away and was one of the first walk-in customers.
Bought two of the first lowers I have several Sota Arms rifles and all have worked flawlessly
6.5 Grendel is my favorite.

Successful Assistance!!

Please forward this info to Louis-I cleaned everything again and noticed pieces come out of the bolt in front of the firing pin. Must be pieces of primers from the normal ammo? Cleaned and put it all back together and shot 10rds of hornady 95gr flawlessly.
I've always heard of picky guns or bad ammo...just never experienced it until now. Thanks again for all your help...your customer service is unmatched!!
