seasam Posted March 28, 2013 Share Posted March 28, 2013 (edited) I opted to remove the rail on my m4 and thought I'd share... -Rail screw holes are M4x.75 NOT #8-40 (8-40 is what I used, but do so at your own risk - read further) -Screws should be no more than .130" long to match receiver thickness I purchased these two plug screws, either one will work: -Brownells hex plug: 080-534-002WB $16.99 http://www.brownells.com/gunsmith-tools-supplies/small-hardware/metal-screws/hex-plug-screws-prod21185.aspx -Brownells slotted plug: 080-533-840WB $8.99 http://www.brownells.com/gunsmith-tools-supplies/small-hardware/metal-screws/plug-screw-kit-prod792.aspx Personally I thought the hex screw looked best, even though they were pricey. I was worried the hex plugs might be a shade too long as the receiver seemed to be 1/8" but they fit perfect. Other options on Brownells include a positive stop screw and a SS option. I secured these screws with Loctite 243 as it supposedly works better if oil contamination is present... and I already had some 243 from my titanium carriercomp mag install (thx Unobtanium for the 243 insight). I'm sure any blue loctite would do the job though. All in all probably a huge waste of time for this, but I like the cleaner m1 type look with the rail out of the way. Plus I was bored.
