Have a CTR on mine, and being it matches my AFG2 (with M-Lok adapter rail on the "SL" handguard), thinking it would throw off the look, although this stock serves a great purpose (batteries, boresnakes, etc).
I just know the Skeleton look of the CTR is great and if it could be mixed with these new improvised versions, would be awesome. I'm sure that doesn't matter to most though.
Hell, if I got one of these, may as well upgrade to the newer M-Lok AFG w/ the Non-Skeletonized look, but being it doesnt loop as steep and no knuckle in the middle, I dont think I could use it the 5+ diff ways I utilize the AFG2.
Not sure if anyone else does this kinda stuff, but one way being fingers only in half of the AFG, pinky stopping at halfway point/ridge, middle finger wrapped around front lip to pull it toward me, and index finger pointed straight forward while doing a "thumb over bore" C-Clamp" grip (Feels great, especially with the SL Grip and AFG2). Another is using my index finger to pull on the front lip w/ ridge and pinky finger around the halfway ridge in middle of AFG , although I never put my entire palm under the AFG2 as if its the "Sole Grip", and the new one looks like a cross between a Strikeforce handstop and an AFG IMO. Magpul is going for the "solid" look now, Miss the Skeleton look.
