Final Update: My 2013 S&W M&P15 MOE Mid — Then vs. Now
A while back, I posted about upgrading my 2013 S&W M&P15 MOE Mid Magpul Spec Series (811053), my very first AR, and asked for opinions on optics and whether upgrading the factory receiver extension hardware was worthwhile.
Well, I finally finished everything! Here’s the original rifle compared with the finished setup.

Original 16” 4150 CMV Melonite barrel, 1:8 twist, 5R rifling

3). Original fixed A2 front sight base
Final Upgrades:
1). SIG SAUER ROMEO8T
2). BCM BCG (MPI/Auto)
3). Radian Raptor charging handle
4). Geissele SSA-E two-stage trigger
5). Radian Talon 45/90 ambidextrous safety
6). Geissele Super 42 spring + H1 buffer
7). BCM 7075-T6 mil-spec receiver extension
8). Forward Controls Design CNF 4140 steel castle nut (nitride)

12). B5 Systems Bravo stock
13). Magpul MBUS Pro steel rear sight
14). Spike’s Tactical A2 flash hider

17). Blue Force Gear Vickers two-point sling
18). BCM BCMGUNFIGHTER heavy-duty QD sling swivels (BCM-QDSS-2)
A Few Updates Since My Previous Post:
I ended up choosing the SIG ROMEO8T over the Aimpoint PRO and EOTech EXPS2-0.
I also went ahead with the receiver extension upgrade, replacing the original buffer tube, castle nut, and end plate with BCM and Forward Controls Design components.
The Feyachi WL65 is gone, replaced by the Streamlight HL-X Pro. I also managed to remove the overtightened mounting screws that gave me trouble earlier.
My goal from the beginning was to modernize my first AR with quality components without losing what made the original S&W/Magpul rifle special to me. That’s why I kept the original receivers, barrel, gas system, and fixed front sight.
After more than a decade of ownership, I’m happy with where it ended up. No more upgrades planned!
What do you guys think of the finished setup?
