The Mattel “Sweet 16” M16A1 feat. US M261 .22 Conversion

After a lot of headache, ballooned cost, and way too much time the M16A1 retro build is finally done and home. I have named it the Mattel “Sweet 16” and it has exceeded all of my expectations and has become one of my favorite rifles to play with. Del-ton barrel and Ruger 556 receiver replace the parts crushed by Uncle Sam. All internals are ATF compliant.
