Rock solid forend - Geissele Super MK4 M-LOK Handguard

I did plenty of research before deciding on the Geissele MK4. Others required weird adhesives or strange mounting. This one had a very nice barrel tube nut and I really liked the "bomb proof" roll pin on the gas block. The install manual is easy to follow and explained how to not only use the set screw on the gas block (drilling small pilot holes for them to sink into), but it also detailed how to drill a 3/16" hole in the bottom of the gas block and install a roll pin, that makes it virtually indestructible.

Overall, the fit and finish is perfect and exactly what I was looking for. I was worried when I ordered it that it would be too short looking on my 16" barrel, since I have a 12" forend from another company that was. Once installed, I was glad I ordered the 13", as it looks perfect.
