The typical piston AR is not beyond criticism of course, it introduces a new moving mass that some shooters allege interferes with accuracy and that sort of thing, but, in this case, it may solve an intractable problem for those who simply can't tolerate the fumes.
SIONICS is supplying the weapon pre-suppressed? If that is the case then they most likely dialed in the gas port hole for a suppressed rifle...correct?
Thank youIf you are asking about the extractor then picture one. When you are facing towards the bolt face (bolt close to you, bolt carrier farthest away from you) the extractor should sit at the 11 o clock position. And like others said the bolt must be pulled out to its extended position when you slide it into the upper receiver.

I'm going to have to suck it up or buy another rifle because I'm never going to be able to get the hand rail off.
ugh has anyone taken off the handguard/rail from the Ruger AR556 MPR? I'm shook.
I have ran my issued M-4 so hard that I have blown the rings completely out of the bolt and it still ran hard! Yes, it gassed the hell out of the rifle and me, but it flat out ran when it needed to run! In all the Hundreds of thousands of rounds I ever fired, I never had a M-16/M-4 go "Hard Bent" once! Closest Was a broken firing pin, which is why I always carried a spare!Yes it does and it is still BS. Find an older addition and it will state the barrel nut torque spec is 30-80 in.lbs. it was a typo and fixed in later additions. Also the method of staking the carrier key is an outdated and nothing I would do. I have multiple copies of TM 9-1005-319-23&P and do use it, to point but there are some errors and/or dated information in it.
Regarding the gas rings, if you remove the bolt from the carrier and look past the gas key through the cam pin shaft hole, slightly to the rear you'll see a shelf and notice the bolt path is not perfectly cylindrical, it is slightly tapered, this taper causes the rings to be pinched together and closes the gap. In fact, a properly built AR will run a single gas ring or none at all in the case of a suppressed weapon.
Well heck, if your coming all the way to Salem, you could stop in and use my Big Arse Vise and all the tools ya need!That rail is a squeeze clamp style, removing the two bolts at the bottom rear should allow the hand guard to slide off. I see no anti rotation tabs so rotating should help pop it off. I seriously doubt Ruger is use a pin anti-rotation method, but I do know they were having issues with their rail rattling off so it is possible they are using a locking compound on the barrel nut/handguard connection.
My advice is don't go down this rabbit hole, but if you'd like to I can remove it. I'm in Oregon City but will need to pick my tools up in Salem, let me know if you'd like some help.
Thank you. I see where it should come apart but it just won't budge I don't have the strength to do it. I'm going to try it on Sunday and see how it goes..That rail is a squeeze clamp style, removing the two bolts at the bottom rear should allow the hand guard to slide off.

Try a few taps with a soft face hammer! You could also CAREFULLY stick a wide flat blade screw driver in the slot and gently twist until it pops loose! Wrap a few layers of heavy masking tape around the hand guard to protect if from the hammer blows!Thank you.
