Magpull BUS

[jonnynitro]

I just bought a set of front and rear Magpull BUS.

Then it dawned on me, the units are plastic and I will be attaching the front sight to the gas block rail, do you guys think it is ok that it is plastic?

I cant imagine it would melt....???

Did you read the instructions that came with the MBUS?

"NOTE: Due to the nature of materials used, this product is not to be installed on any front rail gas block."

Yeah, you dont want to do that... It will melt over time on a SA gun, on a FA you'll be lucky if they last you 2 mags.
