[Dead Corpse]

M16-A2 was the rifle I was issued in the Marines. Since then, I've fired dozens of variants. The entire system has become so modular you can set it up to do almost anything with almost any caliber under 12.7mm...

My favorite "Franken-gun" is still a full 20" heavy barrel, but with a flat-top upper, JP brake, modded trigger, custom grips, and a steel... rather than aluminum, buffer tube for the 3 position stock. Topped with fold down BUIS set up to co-witness on my Votrex red dot... She's my favorite rifle and I can shoot it confidently out to 500 yrds easy, while still being short enough for "run-n-gun" work.

Set it up for the mission and change/swap what you need in minutes.

What's not to like?

Friend of mine built a very similar rifle (using a mil-spec carbine receiver extension, LH upper receiver, & Weaver V3 scope) and loves it. Kind of reminds me of the Canadian C7A2 (if I'm remembering their terminology correctly ;^)...
