michael1778 Posted December 6, 2015 Share Posted December 6, 2015 I had some follower binding in an early production Surefire 60 round model. I set it aside and decided to concentrate on rifle fundamentals for a while. I can come back to troubleshooting it if I ever need capacity like that.

mpom Posted December 6, 2015 Share Posted December 6, 2015 Maybe I've misunderstood, but the root cause for the Surefire failures was due to OAL of ammo. So if you were running factory 55gr, no worries. Once you got into the heavier pills, your OAL increases as does your chance of malfunction. So for an up close hoser match using cheap 55gr ammo the surefire looks to be reliable. But if you were goin to reach out to 200+ yards which is very common for a 3G match, you're going to want a heavier bullet and then failures are induced. Again, that's just what I recall from what I read on AR forums. Cause of malfunctions in Surefire is not only due to OAL, as I have witnessed the mags puke with 55 gr factory ammo. Seems once they get used some, they are often no longer reliable, even with short ammo. A very good shooter friend took his apart for cleaning and inspection, still malfunctions. Mine is only slightly used, runs great and I am willing to sell it for half price! Link to comment Share on other sites More sharing options...
