    Tips & Tricks

    Share your tips & tricks you use in cleaning & maintaining your XCR or any of your other weapons. (1) after seeing sterling99 lost ejector bolt & Juicespeare1 loose ejector bolts, I went home & reloctited all my bolts. All were tight, the gas block bolt had no loctite on it, the barrel bolt & the brass deflector both had red loctite "high strength", all others had what appeared to be "low strength loctite". Cleaned bolts & bolt holes with Break-clean, dryed with compressed air. Put blue loctite on all bolts except for the 2 with red on them (put red back on). Retighten all bolts. (2) while I had the Break-clean out & gun broke down, I thought of Phalanx talking about the recoil buffer weakness. Cleaned buffer & behind buffer with the Break-clean, dryed with compressed air. Put a dab of Permatex Black Super Weatherstrip Adhesive behind each ear of the buffer. Buffer sits solid now, hopefully with no movement, the buffer tit will stay in tack for a long time.

    Re: Tips & Tricks

    Sounds like some good things to think about...

    What is this break-clean you speak of?

    I'm also curious as to why the factory would put red locktite on a barrel bolt (supposed to be removed with reasonable frequency, and I thought it "locked" mechanically somehow?) and brass deflector (doesn't sound like a high stress component?), while putting none or weak locktite on the ejector, which I would assume to be a high stress component that will not be removed often.

    Brake-Clean is a degreaser that leaves no residue bought at any auto parts store. As far as the red loctite on the barrel bolt, I assume that is one part that, they for sure don't want to come off during operation. The brass deflector is made of plastic witch can't take a lot of tourque,is the only reason I can see there.

    I dont think they put ANY lock tite on the barrel bolt at all and I was told by Alex that they would not reccomend it. It has a locknut type thread on it and it really doesnt need it.

    medium strength locktite on all the reat of the bolts.

    I also ran some aircraft grade stainless safety wire thru the ipn retainer holes after i had a couple of clips work loose.

    When I took mine apart there was a red substance on my barrel bolt & brass deflector bolt threads, I assumed it was red loctite. Has anyone else found it on there's?

    Jack, that is probably a good tip about the safety wire but don't understand what you actually did. Got a pitcher of what & how you did it?

    Re: Tips & Tricks

    basically where the trigger group and upper reciever retaining pin clips are I removed them and replaced with safety wire then twisted it and tucked it in tight. you need the good aircraft stuff in .025 or .030 and some twister pliers to do it right. dont over twist either as it weakens the wire.

    it's kinda a pain to get it in there, but it should stay and wont work out as long as you dont over twist and cut it so it wont interfere with anything.

    dunno what robinson has to say about that whole deal tho.

    Re: Tips & Tricks

    I see what you did now, good idea! Did you find the pin clips off, sitting in your receiver? Did you drill holes in the pins to put the safty wire through? THANKS

    I'm guessing the red locktite that looked to be on the barrel bolt was actually use to install the helicoil in the upper receiver (normal Helicoil installation procedure for aircraft). DO NOT use it on the barrel bolt. If you do, it will strip out the upper receiver.
