I made these in 2010 I think, and they have been long forgotten and burried in my basement.
First off is a CheyTac M200
For some reason the cheek rest has gotten a little warped from storage, It used to be straight. And the outer barrel is made from flex tube, and acrylic paint sticks very poorly to it, so the bipod has scraped it off a little. Apart from that i rather like this one. The grip and rear of the receiver is a Brickarms AK47, and the scope is based on one of their rifles, I added a thin slice off trans-clear rod for a glass effect. the rest is random bits and pieces of Lego and a bunch of glue and paint.
The next is a Sako TRG 42
It uses the exact same pieces of Brickarms, and a whole lot of tiny pieces of Lego. A piece of one of my wifes hair clips is in the but stock. And yes, a minifig can actually hold it: http://www.brickshelf.com/gallery/muni/brickarms-mods/billede0042.jpg
