Great value
This Discount Mil-Spec Carbine Buffer/Receiver Extension Kit is very well made and is comparable to the same parts that cost more. They fit my lower receiver perfectly and function flawlessly.

USBetter than the high price ones.
This is very good quality materials. May just as good as the high dollar price ones. Installs with no problems. Works just a smooth and accurate as the others. I will be ordering more of these to put in my build kits.
USGreat value keep a few in the toolbox
the Parts arrived quickly and in discreet packaging. what more could i ask? The real value is having the part you need when you need it. if you can always buy a few extra parts for the next adult Lego project.
USPerfect for Pistols, SBRs, and Rifles
I’ve bought many of these over the years and they all have worked great. No issues with threads, coatings, or anything for that matter. As the title says they work great no matter what time of build you’re doing. However these are mil-spec so pay attention to what stock or brace you buy to avoid slop unless you don’t care about that like myself. It has never caused me any issues in the past.
