Shaved some weight off the old girl tonight


Recommended Posts

Went and bought a bench vise finally and replaced my fore grip tonight. Took off the DPMS quad rail and installed a MWI 12" SS-key mod ultra light gaurd, packaging says it weighs in at 12.4oz with barrel nut, I took off 2 pounds roughly.

I bet the end it's threaded I put mine in the bench vice block, removed the gas block and flash hider, wrapped the grip in electrical tape (so I wouldn't mar it up) and spun it off with a strap wrench. Think the quad rail helped a lot in getting grip with the wrench. I read else where guys used pipe wrenches and wrapped the "teeth" in tape

What's the diameter of the grip I bet it uses the same barrel nut mine does and that's where all the dam weight was

Yeah, the thing looks like it's probably threaded and would come off with a strap wrench. The diameter of the free-float tube is 2.27 inches.


Does this mean I would be using a different barrel nut with a different foregrip and that's where the weight savings would be?

I changed mine for two reasons, I thought the quad rail was cool when I bought it, but I ended up not liking it. It's bulky IMO and it gets snagged up in my hunting cloths, also I realized how heavy the gun was after I bought it and wanted to lighten it up. It really wasn't any trouble per-say but by buying the new hand guard I got a look I wanted shaved off some weight and bulk and eliminated 3 rails I really wasn't using. Also I can now ditch the quick release sling post I was using because the rail has 3-4 drilled holes to accept a sling at
