Need a Low Pro gas block for my S&W MP15 16" barrel, diameter 0.75, just bought the DD Lite rail 12". Any suggestions?

Chop down your front sight base.

| I have a carbine length gas system on a 16" barrel with the standard A frame front sight post. I would like to make the rail system a mid length so i can have more room. Is it possible to replace the front sight post with a low profile gas block and then simply put on the mid length rails? |

| Cheapest and most reliable way is to take a Dremel to your FSB to retain the solid taper pin mounting. If you must buy a low profile gas block look for an extended length version to cover the cuts in your barrel left from the taper pins. I like the extended Midwest Industries version because it has three set screws vs only two. The extra set screw is just a bonus in my opinion. |
