Customized Colt 6920

My brother owns this Colt 6920. Since suffering a broken shoulder after a motorcycling accident, he has never had the same range of motion as before (think Sen. John McCain). The factory rifle is a fine rifle by itself, but I wanted to do something nice for him. My brother has shown me some amazing generosity recently and I wanted to pay him back. My intention was to leave the reliable colt guts alone and only "spruce" up the gun with the added accessories. I also wanted to keep the gun light or lighter than factory.

The rifle was a (2012 vintage) plain jane, bone stock Colt 6920. I first started by removing the front sight base/post and cutting it down to a pinned gas block. This was a first for me and I was a bit apprehensive. A little work with an angle grinder, grinding wheel, and aluminum black and the job was complete.

I wanted to replace the standard handguard with a new BCM KMR-A to give him a bit more room and accessory mounting options. I went with the 15" variety because it was only a couple more bucks difference in price. I also purchased a BCM Comp Mod 0 muzzle device and Mod 4 gunfighter charging handle for the upper. I topped off the upper with new Arms Inc. flip up polymer sights to help maintain the lighter weight.

On the lower, I replaced the butt stock, pistol grip, and trigger guard with the new BCM variety. I also replaced the factory GI trigger with a Geissele S2S that I had already.

Here is the gas block completed and on the barrel.

The finished product:

The final weight on the bathroom scale with irons only and no magazine was 6.6 lbs. Per Colt's site, the standard 6920 is 6.9 lbs. The rifle feels quick to target in hand. I will be throwing a spare Aimpoint Comp M that I have with ADM qd mount to send back to him. I tested the gun and it functions perfectly.

My brother has no idea that I did this to his rifle, so I'm hoping these mods will put the wow factor in his rifle when he sees it. What do you guys think ? Do you think a H2 buffer would be a beneficial addition ?

Thanks for looking.
