Polymer Front Sight on M&P 15 OR?

[JLM]

Hi All,
I am about ready to pick up my first AR. I've decided on an M&P 15 that is on sale at Cabela's starting today. It appears to be the "OR" model, but with the Magpul stock, foreend, grip and magazines. It has no sights. I was wondering if the Magpul polymer backup sights would work on this model - specifically for the front? I think I read somewhere that the front could get too hot and melt the polymer?

Thanks

No polymer sights on a railed gas block. You will need to get a metal front flip sight, there are many good options out there. As I recall the OR is same plane, so make sure you get an appropriate set of sights.

Thanks for the info.

Here are some choices. ironically, you need to avoid the sights marked "gas block" because they are for shorter "compact" gas blocks and the OR has a flat top height rail atop the gas block.

I bought the Magpul flip up sights for my M&P15 piston gun. The front sight did get extremely hot after running a few mags through the gun, but it seemed to be no worse for wear. Rather than worry about the front sight failing at some point I decided to go with a metal sight and decided on the Midwest Industries sight. It works with my Magpul rear sight and they both co-witness with my EOTech XPS2.

Thanks Lee,
I like the look of those. I was thinking about going with the Troy folding sights, but these are a bit easier on the wallet. Every time I've priced something at Midway though, by the time they added sales tax and shipping, it was always less expensive somewhere else.
