I found out the Hard Way that most free float handguards for AR-15 will not work with Gas Piston Systems.

  1. I got an idea. how about not look for just a run-of-the-mill $60 POS. and get one made for a gas piston system. there's hundreds of them out there. another idea would be if you did buy a pos; buy one that covers the gas block and then grind it out so it covers the gas block. and then your rails all lineup sweet like. with all the different crap rails you showed us you could have but one decent one and that would have worked with no modifications and function the way it it should. just a thought………….

  2. Gas piston AR's absolutely suck. It a solution in search of a problem. You take an elegantly simple design and add more moving parts to it. The Filthy 14 BCM midlength went well over 40,000 rounds with no cleaning and didn't miss a beat. I know of no piston AR that's even hit 10,000. When Eugene Stoner went to Knights Armament the gas system was not one of the changes he made to the gun

  3. i know the video is old but there is a low profile gas piston system as well as the osprey system that work with any DI gas block but the gas chamber is stillpretty big.

  4. Oh, you converted a DI over to a piston? I already own an AR piston rifle. Wonder if I'll have better luck w/ mine, or ya reckon there could still be problems with it. Too bad there's not a compatability list, a guy could look this crap up, BEFORE going thru what you had to. Man, I'll bet your blood pressure was ready to blow the top of your damn head off! I feel for ya friend!

  5. What you mean to say is that cheap, dog shit, $60 Chinese rails won't fit piston rifles…..at least at the time this video was made. I got into piston AR's almost 3 years ago and they have tons of bad ass rails that fit. Both 1 peice free float, 2 peice free float, and 2 peice drop in rails from a variety of manufactures were available at the time this video was made. Hell… you could've even gotten a Magpul MOE handguard that works with piston AR's.
