two questions:

(1) its not what Ra tech offered in 2015 hardened heat treaded carbon steel for their new M4 bolt carrier ?

(2) where i can order a WE m16a1 spare stock bolt stop & bolt carrier parts online ?

RA-Tech does not have a good reputation of working, out of the box parts. If you're new to gas guns and want to play more than tinker, I would suggest in my opinion to stick to the stock bolt carrier, or a new stock bolt carrier rather than a RA-Tech one.

If you like to tinker and are open to the idea of grinding and modification, then get the RA-Tech bolt carrier.

There is no aftermarket bolt carrier for the WE m4 that is indestructible; the steel will wear out no matter what unless you get some sort of custom cnc machined bolt carrier with high-quality, heat treated carbon steel.
