I have an SLR Solo Lite and an ALG V1.  Both awsome rails.  I like the Magpul Type II rail covers and they don't fit on the SLR but do on the ALG.  I can't push the centerpiece all the way in because the lips can't lock in place as they don't go far enough in to clear the slot.



Standard M-LOK accessories that use screws work no problem for either.  There are enough threads to compensate for variations in mounting thickness.



What rail covers are out there worth getting and won't break the bank?

I just got some of the new Magpul Type 1's.  They are pretty nice, slim too.  Strike Industries also makes some decent looking covers.

I've been conversing with SLR.  The Type II works on their 5.56 rails.  They will check on the .308 rails (what I have).  Those slots appear thicker.



ALG (5.56) =0.085"



SLR (7.62) = 0.210"

What does the mlok spec call for on that dimension?

.080" min - .150" max

I've been seeing more and more MLok stuff that doesn't adhere to the TDP.
