Hookster Posted July 19, 2009 Share Posted July 19, 2009 Hey All, Can anyone who has removed their receiver rail tell me if the use of heat is advisable or not really needed? Thanks, Hookster Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted July 19, 2009 Share Posted July 19, 2009 It wasn't needed on mine. It wouldn't hurt if they're stuck or you can't get a good bite on the screw. Be careful not to loose the washers that are under the screw. They usually remain stuck in the hole. I used blue locktite on the SideArmor replacement screws.

Hookster Posted July 19, 2009 Author Share Posted July 19, 2009 Thanks, I'll have heat gun standing by just in case. Is whatever threadlocker they use at the factory in Italy on the mag tubes etc. in the "high strength hold" range like red loctite or more like the blue med. strength?

Unobtanium Posted July 19, 2009 Share Posted July 19, 2009 Hey All, Can anyone who has removed their receiver rail tell me if the use of heat is advisable or not really needed? Thanks, Hookster The rail is attatched with screws and lock-washers, at least on my last M4. No lok-tite was used. Quote Link to comment Share on other sites More sharing options...

I would say a cross between the two and an epoxy or something. Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted July 19, 2009 Share Posted July 19, 2009 I can't recall if my receiver had locktite from the factory or not. I removed it like 5 years ago. You'll want the locktite with the Sidearmor because there are no lock washers used. The replacement bolts are hexhead. Be careful not to overtighten and strip the threads in the receiver. They don't have to be loose by any means, but don't crank them down like a lug nut. I didn't bother to put locktite on my new mag tube. I like the ability to pull it during cleaning. I scrapped shooting this week since it is 122 degrees in the shade, and there aint much shade. Even at night it is 105. Quote Link to comment Share on other sites More sharing options...

Hookster Posted July 19, 2009 Author Share Posted July 19, 2009 quot[e=Posha;89634]If you have a fairly new M4, in theory you will only need a metric hex wrench and a heat torch to remove 6 flat head hex screws on the upper rail. Some vendors will include the wrench and 6 extra screws in the very likely event that you might strip them. (The threads are welded with lock-tite). The recommendation is that you heat the screws with torch, then very simply back the screws out. Yeah right! I stripped three, and now the unit is at a local machinist for damage control. t's a bit tricky, and you have to be careful not to overheat the aluminum. I'd seen the post above from 2008 in a thread about installing the Brugger and Thomet forend and it made me a little nervous about getting the screws out. Good to hear you guys didn't have too many issues with removal. 122......mmmm..toasty Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted July 19, 2009 Share Posted July 19, 2009 Hottest city in North America. Bullhead City, Arizona. It's humid today and I'm on patrol outdoors. Sucks big floppy donkey dong. Quote Link to comment Share on other sites More sharing options...

Meh, that rips. For their part, I will say the LSUS cops impress me wearing their IIA body armor and pedalling around on bikes at times on the LSUS campus in 100* weather. Most of those LSUS cops are pretty good people too, or at least when I went there they were. They hand-picked them from units all over the state basically.

StrangerDanger Posted July 19, 2009 Share Posted July 19, 2009 I wouldn't use a torch on the receiver. Only a heatgun. The only place a torch is needed is on the receiver extension. The average heatgun just doesn't have the balls. Vests do suck in the summer. The guys in Iraq have it worse though. Much worse. Quote Link to comment Share on other sites More sharing options...
