We have been selling the same thing at gun shows here in Tx for a year. $14.00.


Do you do the gun shows in Amarillo?

Ar15extreme. Better kit. Cheaper


Checked on this: Shipping costs are ridiculous and immediately make this no longer a good deal. They are also asking for gender when you check out. Why do they need to know your gender? Since they sell firearms I can understand the birthdate request but I don’t understand why they need to know my gender.

I passed because the shipping charges were nuts. $12.35 is way beyond reasonable for something that fits in a standard envelope.

I agree re: shipping charges. Surely some other source for complete/partial parts package for those of us too lazy to put one together?? Post info if you’ve got it.


Anybody try Brownells, MidwayUSA, Optics Planet, PSA


That’s why I built my own. First I got a little every time I went to JSE Surplus. Good think for me is I live 15 miles from them and did not have to pay any shipping. Second I got things that are not in any kit I’ve seen. With what I ended up with I can completely rebuild my lower’s small parts twice over and it cost me about $50.


I built my own kit, but it includes additions. Firing pin, gas rings are the most common, but I have at least one replacement for ever spring, detent, extractor parts, ejector parts and trigger group springs. Guess I just like being prepared for anything! LOL
