LEGO Heavy Weapons Posted May 11, 2012 in Other Gear & Gadgets by Steve Johnson with 16 CommentsTags: culture, DIY, gun, howto, lego The “working” Lego guns featured in the new LEGO Heavy Weapons book are amazing. I love the shotgun and Enfield. The book is written by a 17 year old! It is selling for $24.95 at NoStrach. Use coupon code ARMORY and get 30 percent off.
