Since I can't buy ammo and mags due to the silliness, It's time to dress up the ole MP15-22. Been looking at a Kineti-Tech barrel shroud, (fake can, they do look nice)

I have installed a bunch of barrel devices on full size AR's and know there is a recommended torque. However, with the 6" shroud, there is no way you can grab the barrel with a vise and blocks. Is hand tight good enough, or is there a locking device in the shroud? Should a lock washer be used?

It will be going on a threaded barrel.

Thanks in advance....

I was told not to put a locking device (lock washer, lockite etc) on the shroud because in the process of removing it you could damage your upper (assuming you are putting this on your 15-22) because there is no way to hold the barrel to stop it from tearing up the polymer. I put mine on hand tight and just keep checking periodicity while shooting and so far it has never come loose after hundreds of rounds.

I'm thinking of trying a split washer on my Kinetic-Tech... It has come loose on me after one mag and it was hand tightened.

Don't you guys know that barrel shrouds are a military feature and therefore a danger to children and police officers?

Just my two cents...if you're on national TV, then you should know the terminology in a bill that you support. This just goes to show how un-knowledgable our law makers are on gun issues!

Hand tight.

Cut up a rubber patch or inner tube. You can trace the shape/size you want with sockets from your toolbox.

You can make several to use as alignment shims or just one to give it a locking affect.

Blue LocTite on the threads. DO NOT USE RED, that will take heat to remove!

Thanks for the suggestions folks. I'm going to pick one up and see how it works out. They really do enhance the look of the 15-22. (IMHO )

ctj50, I am with you on this one.
I have been drooling over a kineti-tech shroud for a couple of weeks. It just adds an extra layer of awesome or something.
Be sure to post up some pictures when you get the new shroud installed.

You can re-use your crush washer since you are not going to put enough torque with your hands to really crush it. Or you could use a new one.
A split ring washer will cut some material away from the shoulder of the threads or the back of the shroud or both. I would not use one.

Yea, I'm leaning that way my self. Re-using the old one sounds like a good plan if the hand tight option doesn't work out.
