Can the Magpul polymer front sight be used on a steel gas block or will it get too hot for the plastic? My railed YHM gas block is too low for this sight but I was going to use one of their aluminum risers to align the front with the rear Magpul polymer on my flat top.

Won't be the correct height on a gas block. You need a sight that is designed for a gas block. MBUS sights are designed to sit on a rail.

Even if it was the correct height, Magpul says not to use 'em on a gas block, because they may melt.

I use the YHM gas block riser with the Magpul BUS on my 458 Socom and it works fine but.... I usually don't shoot more than 20 - 40 rounds max per range session.

Thanks. Guess I'll use different sights.
