Came across this interesting article on someone deciding to make his AR15 lighter.
Don't own one (YET) but hoping to get one someday when I get DSS status.
Would this be allowed if you had it licensed under DSS as the mods don't affect any of the functions?
Darkop’s Super Lightweight AR-15 Project
Our friend Darkop started a project to build a super lightweight AR-15. He could have used various non-standard polymer receiver parts, but chose instead to see what he could do with standard aluminum parts. Here are the results of his project:
http://762precision.files.wordpress....pg?w=497&h=164Rainier Arms slick-sided upper with no forward assist. Upper with bolt and carrier group weighed 3 lbs 5.8 oz.
http://762precision.files.wordpress....pg?w=497&h=118Daniel Defense 14.5" lightweight profile barrel, low-pro gas block, barrel nut, and battle comp compensator.
http://762precision.files.wordpress....pg?w=497&h=324Daniel Defense fixed iron sights. 2.8 oz.
http://762precision.files.wordpress....pg?w=497&h=179Troy handguard - 6.0 oz.
http://762precision.files.wordpress....pg?w=497&h=633Squaring the upper receiver.
http://762precision.files.wordpress....jpg?w=497&h=94The barrel dimpled for the set screws on the gas block.
http://762precision.files.wordpress....pg?w=497&h=373A little grease for the barrel nut.

http://762precision.files.wordpress....pg?w=497&h=217It's getting uglier.
http://762precision.files.wordpress....pg?w=497&h=255Loosing weight, getting skinny and svelte!
http://762precision.files.wordpress....jpg?w=497&h=95Lightening the receiver extension.
http://762precision.files.wordpress....pg?w=497&h=151Drilled out the standard GI trigger guard.
http://762precision.files.wordpress....pg?w=497&h=217Touching up the holes with Dura Coat. Then baked in the oven until medium rare!
http://762precision.files.wordpress....pg?w=497&h=346The DuraCoat is still wet.

http://762precision.files.wordpress....pg?w=497&h=217My old school semi-circle Colt 6920 bolt carrier group.
http://762precision.files.wordpress....pg?w=497&h=180That weld really looks better than the picture shows :-(
http://762precision.files.wordpress....pg?w=497&h=229Drilled out the brass deflector . . .
http://762precision.files.wordpress....pg?w=497&h=206. . . but not all the way through.
http://762precision.files.wordpress....pg?w=497&h=207Overall weight when done: 4lbs 14.5 oz (1.8 kg):g:
http://762precision.files.wordpress....pg?w=497&h=200The pretty side.
