Hello ARVUL. Nice story on your mods.
Just purchased a M&P 15-2 OR myself. Well into the bolt-on LEGO fun of modifying it, before I finally get time to take it out and shoot it.
So far, I also have the Hogue grip, added a Magpul front (also has metal heat guards), plus a couple of MOE picitinny rails in the slots, one for a bipod,
one for a Streamlight laser on the left side, just within thumb reach, and added Tacticon flip-up iron sights, and a bunch of Magpul 30 and 20 round mags.
Got a Holosun red dot ordered. Probably will add a Magpul slanted grip behind the bipod. Bore-sighted it for the sights and Streamlight in a 50-foot hallway in my building.
Good to go until I get to the range.
