Geissele Rail Failures Mega-Thread
I’ve had a MK16 from around the time the whole thing came out. I really just liked the rail so when URGIs went on super sale I grabbed one. I also ended up selling that one off because I like LW barrels, but before I did so, that gun was blown off a range bench onto concrete. The Razor that was on that gun is at Vortex right now, as I suspect it may have been damaged. Never saw any issues with the rail itself, but I wasn’t using irons or a laser so I didn’t have anything to check zero with. I still like the rail a lot and bought the kit to be used on a separate upper. I don’t know how barrel it fit is as I didn’t install it. The barrel was suspect for a bit though so it’s been looked over by at least two different people - I assume if the nut was sketchy, that would’ve been mentioned. As far as the flex - I assumed it’s just like doc said. This design makes a sacrifice, I assume that’s happen to most similar rails out there, especially because last I saw, there was no evidence of whether the rail flexed or the barrel, or most likely IMO, both.
No other experience with G rails, but figured since I have one of the ones that are apparently questionable, my experience has some relevancy. I am a huge fanboy of their flat faced triggers, scope mounts, and even prefer their ACH to the Raptor though, so maybe I’m just a fanboy.
