gotm4 Posted December 31, 2008 Share Posted December 31, 2008 Now that brownells has made a barrel extension with M4 feed ramp cuts, Who'se uppers already have them?Lets NOT discuss the merits or need of the M4 ramps VLTOR, LaRue, CMT, Daniel Defense, LMT, Colt. CMTs can be had with or without M4 ramps, Daniel Defense A3 uppers don't have the ramps but the A4 does. Link to comment Share on other sites More sharing options...
caspian guy Posted December 31, 2008 Share Posted December 31, 2008 (edited) You can get Saber Defense uppers with M4 ramps. Also CMMG sells uppers with M4 ramps Peter Adams FY-39604 Edited December 31, 2008 by caspian guy Link to comment Share on other sites More sharing options...
XRe Posted December 31, 2008 Share Posted December 31, 2008 My understanding, per Mark LaRue on arfcom Industry forum, is that the LaRue upper does not have the cuts? Link to comment Share on other sites More sharing options...

uscbigdawg Posted December 31, 2008 Share Posted December 31, 2008 (edited) My HKS (or TKS can't remember) basically Sun Devil does not, but I cut them in with a Dremel. It's VERY easy. Rich ETA: And yes XRe, I can cut up an AR, but I'm still nervous to touch my Rusty Kidd trigger job.

GentlemanJim Posted December 31, 2008 Share Posted December 31, 2008 Even standard ramps and receivers can benefit from some blending between the extension and receiver. You can blend an M4 into any upper with ease. Jim Link to comment Share on other sites More sharing options...
srt205 Posted January 26, 2009 Share Posted January 26, 2009 I think pretty much everyone uses the uppers with M4 feedramps. I may depend on what is available at the time also due to the buying fenzy. srt205 Link to comment Share on other sites More sharing options...
