Armaspec smb w buffer tube - just say no - Armaspec H2 Gen3 Sound Mitigation Buffer Kit

This is the 3rd time I bought an Armaspec product. The first two gave my rifles a cycling problems. Figured the buffer was too heavy so went and bought a lighter one…still a problem. Couldn’t return due to return window closed.

Stumbled upon this one which is different than the SRS, as it is supposed to be lighter. It certainly felt heavier, but worst part is, after installation, when I manually pulled the charging handle back, the bolt failed to go back all the way and instead stopped an inch short just beyond the magazine feed, which will give you failure to feed.

Not sure if the buffer tube is too short, or something else. Either way, never wasting my money on Armaspec again. Just went ahead and bought a JP SCS. Buy once cry once.
