New Upper Receiver Specs
Posted 12 May 2014 - 12:30 AM
There seem to be quite a few dimensional difference between the LM4/Magpul and MKM. Most obvious is the upper receiver tabs. I was just wondering if the revised one-piece upper receivers will the fit the old LM4 spec'ed receivers? Or will they fit the MKM receivers? If the newer uppers fit the MKM, I would assume that there will also be a revision to the LM4 lower?
I'm trying to gauge how much effort I should put in to tuning/upgrade my Magpul. It just wouldn't make sense to put in a lot of time if I would have to switch over to a new system to use the new receivers. I've also been waiting on the PTS BAD Selector, but I suspect that they may only make it for the MKM, especially if the new LM4s have the same dimensions.
