That's some sub genius level stuff right there...... - TacFire A2 AR-10 .308 Fixed Buttstock Kit

Pro: Even without instructions the components are easy to assemble.

Con: The buffer plug weights are loose, so they rattle around inside of it. A minor issue that should be addressed.

Con: The buffer plug has cut outs that allow the plug to pass by the buffer retaining pin. This was discovered during a function check of the lower receiver, the buffer and the spring pop out. I cycled the completed rifle several dozen times to see if the plug can get past the pin when fully assembled, it does not seem to. However, when you break the weapon open the spring and buffer jump out at ya.

So, the moral of the story is that if you put this on your weapon, it will spontaneously disassemble itself when you remove the upper receiver from the lower receiver. One might see this as a feature rather than a bug, but I certainly see it as a bug.

Does it work? Dunno, haven't taken it to the range yet but it does seem to cycle manually just fine. Generally disappointed in the quality/design of the plug. I suspect I will have to trade it out, or get a longer retaining pin. With any luck someone at the company reads this and fixes the issue or adds a longer retaining pin to the kit.
