usmc1974 Posted January 31, 2013 Share Posted January 31, 2013 Are the piston ar's easyer on the bolt then the gas? Quote Link to comment Share on other sites More sharing options...
fastshooter03 Posted February 1, 2013 Share Posted February 1, 2013 I wouldn't think so. Normal AR the gas is forcing the bolt forward and the carrier rearward at the time of unlocking. Piston is just slapping the carrier rearward to unlock everything so you would think it is harder on the cam and bolt. Nick Quote Link to comment Share on other sites More sharing options...

gixxerjunky Posted February 1, 2013 Share Posted February 1, 2013 Piston AR's have more recoil as well. Some believe to how violent the action is. Quote Link to comment Share on other sites More sharing options...
Steve RA Posted February 1, 2013 Share Posted February 1, 2013 How does the bolt get pushed forward when it's locked in the locking lugs ?? Quote Link to comment Share on other sites More sharing options...
usmc1974 Posted February 1, 2013 Author Share Posted February 1, 2013 So it is better to stay with the gas system? For longer bolt life.I never knew bolts broke this much, how many round might it take to break one? Quote Link to comment Share on other sites More sharing options...
rcollier Posted February 2, 2013 Share Posted February 2, 2013 Steve RA...The "bolt forward" may have been a misnomer but it does move slightly and takes the presssure off the lugs as the gas comes in behind the gas rings holding the bolt stationary (linear) as the carrier is forced rearward and the bolt rotates free as the cam pin does its' work.

fastshooter03 Posted February 5, 2013 Share Posted February 5, 2013 I only have one piston rifle so my experience is limited in that regard. But I do prefer a normal gas system's lower recoil impulse and smaller profile on the barrel Bolt failure is a hard thing to predict. If you do some internet searching you might be able to come up with some numbers. I like to think I have some extra life coming since I use the JP enhanced bolt. I have seen a lot of chipped lugs on 308 ars w normal gas. Nick Quote Link to comment Share on other sites More sharing options...
