I don't understand the fascination with piston ar's unless a guy wants a folding stock. I have a piston rifle, it's called an ak.

I know this isn't what you asked but it will keep conversation flowing maybe, there's not enough of that here.

It's cause the conversations here are very respectful and to the point.

Also, 10-4 on the fascination thing. I am not convinced about pistons at all. I've been building them longer than just about everybody else and their only role in my opinion, is to reduce the heat transfer in Full-Auto Mode. Otherwise, they cause undue strain and wear and tear, on the charging handle and the carrier key system. The direct impingement is a tried and proven Combat System, you just got to keep it clean, so what.

i had been doing a bit of research on piston systems looking for ultimate reliability right up until my best friend returned from iraq. i asked him about his M4 and how reliable it was. he said he fired over 10000 rounds through his weapon in 6 months, 1/3 of which in FA, and never cleaned it. guess how many malfunctions he had... thats right ZERO...
but man... a sweet folding stock SBR would be tasty.... :twisted:

Well said... This "piston system awe" strikes me as a sandpit comando revival of the "Rhino Op Rod Kit" in the late 80's early 90's. I had the chance to run a few K rounds through some of the "new" systems prior to being available... If I'm pounding the snot out of the shorty 16's its ok but, I'll take a tube gun anyday...
If you build it they will come, If I build it... I'll take the damn thing home!

Yeah, and the Rhino Guys looked at what I was doing and thought they could do better, does the sound like the 458/50 guys with their other big-bores? Anyway, I've done the AK and FAL systems, using their parts and still am not convinced, but, if ya likes'em, use'em, they work pretty good..t

When I talked to Bushmaster, the tech guy told me they had tried their pushrod conversion kit and they didnt have positive results with the 450, so they dont recommend them with the 450.
