I assure you that it wasn’t planned, but it seems that I am, inadvertently, testing all the non-direct-impingement AR clones these days. I picked up a couple JAKLs which are using the long stroke gas system of the AK. And, for no reason that I can think of except for a wild impulse, I seem to have picked up one of the new Brownell AR-180 reintroductions. This particular flavor of AR-wannabe uses the short stroke piston system. What both of these designs have going for it is that they allow for a folding stock, and they are a bit more hygienic in terms of keeping fouling out of the action.
Years ago, I took a defensive carbine course. Unsurprisingly everyone was using some flavor of AR-15. I recall that I could fire about 400 rounds before the gun needed a couple squirts of lube or some quick cleaning to keep it running. In theory, the non-direct-impingement guns should run way past that without needing cleaning. Guess I’ll find out.
For those who are a bit unfamiliar, Brownells took the concept of the AR-180 and ran with it. They updated the design to work on any milspec AR lower, which is a huge win since it allows the gun to use plentiful AR mags rather than the proprietary AR-180 mags. (Although, yeah, you could modify an AR mag to work. Usually.)
The tradeoffs are the usual ones when moving away from the direct impingement system…a hit to accuracy since there are now moving bits along the barrel. In fact, best I can tell, the only semiauto .223 carbines out there that dont have moving parts on the barrel are the direct impingement ARs, the gasless HK93, and the wierd lever delay of the FAMAS.
If someone would bring out an HK93 that takes AR mags and has a bolt hold open I would buy a dozen. (And, interestingly, Hk did exactly that.)
So, as soon as a couple accessories show up for this thing, I’ll take it out and see if it’s got anything going for it. Right now, the most interesting thing about it is that….its NOT an AR.
