Aero let me down

My latest build is based on Aero Precision upper and lower receiver, Atlas S hand guard (I find fantastic) and buffer kit. I have always been pleased with Aero products until the buffer kit was inspected after noticing the spring hanging up. Thinking it might be the spring, I installed one from another rifle and the problem was still there. Looking inside the tube I could see deep machine marks and no evidence of dry lube. I am not sure if Aero Precision manufactures the tubes in house but this is the first time having a problem with there products. This experience gave me new thought into buffer tube quality and not to purchase based on price. Lesson learned and it only took 43; years. As for Ar15discounts, the shipping is very fast and prices are low, I will continue shopping with them.

Well made is understatement!

I have through the last few years and by far this has been the best one I have ever used. I built with a Hogue stock and there is absolutely no play whatsoever. The coating is perfect along with the machining. I am more than pleased. This was my first order from AR15discounts and I as stated about how good the product is wait for your experience with this company, they are GREAT!! Staff is knowledgeable about their products if you need to talk with them, website works excellent, rapid notification of and shipping documentation, and the shipping totally amazes me. I live in the central US and I receive their shipments quicker than stuff I order local. Oh, and their prices are lowest around. GOOD JOB AR15DISCOUNTS!!!!!
