Hey guys, been reading through the forum and finally decided to register and make a post. A co-worker of mine talked me into making my first AR from the ground up. I've done a few things like converting saiga's and adding rails to ARs but nothing this major. Any who, this is my build list and would like some opinions on it. 18 inch threaded .812 diameter krieger barrel ordered today. Waiting begins :( Mega Maten Rifle Length Monolithic Ambi Combo from Rainier. Geiselle 3 gun trigger from Rainier. AAC 51T Muzzle Brake from Rainier. Hoping that the Silencer Co Saker comes out in .308 sometime. Dpms complete BCG from Cheaper Than Dirt. Dpms Rifle Length Gas tube from Cheaper Than Dirt. AR15 Panther Tactical Grip from Cheaper Than Dirt. Magpul Mbus for BUIS. American Defense MFG bipod qd mount. For a bipod I already have. Lower Parts Kit without trigger from Fulton Armory. Magpul PRS Buttstock Assembly from Fulton Armory. Includes rifle buffer tube, spring, and buffer. Larue QD Scope Mounts. Leupold Scope..... Undecided thinking mk4 of some kind with the h 58 reticle. Gas Block...... Undecided needs to be low profile .936 diameter. Just cant decide if I need an adjustable one just in case I buy a suppressor for it someday or not. Any suggestions or thoughts are appreciated but I'm really here for answers to the scope and gas block questions. Also let me know if I left anything out that I may need. Thanks in advance. Chris
