@kevintran7208 Loctite (with the correct heat rating) is a perfectly viable solution for civilian owners working on a clean bench at roughly room temperature. But an armorer working out of an M113 in freezing conditions needs another solution.

I didn't get a good look down the hand guard from the barrel end, but it looks like you can get "rags on a stick" down there, and you can get strips of rags though the M-Lock holes.

@Phoenix-x5e EVERYONE will pick an MP5. People have differing opinion on how well the roller delayed system works for 7.62 and 5.56, but everyone agrees that for 9mm it is just the most butter smooth and easily controllable system ever invented.

If they charge what those crush washers are actually "worth" (+something for packaging and handling) so a zip bag with 7 is, say, $3 and a box with 700 +/- 3 (quick-weighed) is, say, $50, then they could get enthusiasts to buy a lot of extras. People get stingy on running costs, but don't mind laying down dole for the item itself. Unfortunately a lot of marketing people don't realize this, so they lose more on big item sales what they try to "rip off" on things where it practically would make no difference if they sold at break-even.

Drop it in mud by accident and clean it without taking the hand guard off because the crush washers and torque wrench aren't standard issue. I do understand the appeal of these free floated barrals with "attach all the things all the time" hand guards.... but having trained many conscripts and recruits myself... oh boy, is someone doing pushups soon :P

@Dmac6969 Wha?.... Because service contracts have very precise stipulations that must be followed by both parties. If the contract says that washers are single use and the screws must be torqued to XYZ with a calibrated torque wrench, then that is what the army will do, because if they don't the manufacturer has a get-out-of-jail card for any and all warranty claims surrounded to this area of the gun (obviously they can't claim that the reason the butt stock snapped is because the hand guard wasn't attached correctly).

@squidwardo7074 Of cause they're not. But they are going to be told to clean the bloody thing. Which is going to be "an interesting exercise" when you can't easily get the hand guard off.

@Dmac6969 As a civie, yes. But as an armed force with a two-way legally binding contract, no.

@BobSaint I didn't get a clear look from the front, but it looks like you can just reach in and unscrew the gas plug. Anything else would be insanity.

@kevintran7208 No. The hole and the backside of the bolt has to have matching ridges. These are specifically designed to work in areas where thermal expansion and contraction is a factor. The "nylon" (don't know what it actually is) between the two serrated discs takes up travel caused by expansion and contraction, which ensures are relatively even bolt pressure in the entire temperature range.

CZ knows how to do marketing: Treat Ian like nobility, and everything else will sort itself out.
