[QUOTE="NikatKimber, post: 3020205, member: 423"] Plans that will affect weight: Weight Loss: Remove A2 Screw and Spacer and replace with A1 Screw. Should lose just over .8oz Mill Bolt Carrier. I expect to cut at least 2 oz there. Mill groove on upper receiver. I expect to remove ~.25oz. Speed cut on hammer. ~.25oz. Shave down the A2 grip - I hate the finger bump anyways. I'll see what I can get here, and post back. The grip starts at 2.4oz. Weight Gain: Add sights, and corresponding mounts. The weight shown above does not include any sights, and ALL the picatinny rail sections are removed from the handguard. I will add one short length back to the muzzle end of the CF tube to mount a front sight on. Eventually I will mount a Vortex Venom 3moa RDS. It is 1.6oz including the low pic mount from Vortex (according to their site). I will use a .5" riser to make it the correct height. The riser I am looking at is just under an ounce. So that will be just over 2.5oz total. Until then, I am going to find some lightweight "irons" to install just to have something to aim. Swap A2 FH for a muzzle brake. End goal here is something super light, yet effective in reducing recoil. Faxon "SLIM" brake is 1.12oz. The best performing brake in the [URL='http://www.thetruthaboutguns.com/2016/10/jeremy-s/ar-15-muzzle-brake-shootout-3/']TTAG Muzzle Device Shootout[/URL] series is the Precision Armament M4-72, which weighs 2.55oz. The Faxon is ~$60 and the M4-72 is ~$90. For now, in the interest of budget, and getting [I]something[/I] that reduces recoil, I am planing on using a cheapy from JSE.
