Bolter conversion for m4 Airsoft gun ------------------------------------------------- UPDATES: Aug 2017 Fixes: July 2017 ! 2 parts have been updated: Boltergrip3.stl and BolterOuterBarrel4.stl This now allows the handguard to lock in the outerbarrel :) -------------------------------------------------- The donor used for this was a G&G Raider Polymer bodied airsoft M4. The inner barrel, front iron sight, metal reinforcing bar and bushing from inside the rail system were disposed of. If you choose assembly 1 or 2 also remove the stock and the stock protrusion from the receiver sawn off. The Charging handle was also removed. (Included pictures show the result). There are 3 ways to use this kit: 1: Front wired using all parts with a QD attachment at stock end. 2: Front wired using all parts without a QD attachment at stock end. 3: Rear Wired ( in which case do not use the Stock End parts) Using other models of airsoft gun. Some modification of these parts may be required as this was custom made for a G&G combat machine raider that was front wired. The QD used for this was from: http://www.ant-supplies.uk/gun-sling-fittings/flush-fit-gun-sling-swivels.html (picture attached) Parts List BolterFrontSight BolterRearSight BolterGrip1 BolterGrip2 BolterGrip3 BolterGrip4 BolterGripLock x2 (these go in after the nuts to keep them secure, if these dont fit tightly please gluse them in after the nut goes in) BolterGripRib1 x5 BolterGripRib2 BolterOuterBarrel1 BolterOuterBarrel2 BolterOuterBarrel3 BolterOuterBarrel4 BolterStockEnd1 BolterStockEnd2 BolterStockEnd1withoutQD (this is the optional end for those not using a QD M5X25MM Bolt (for stock end, you can use a 30mm or 35mm also) M4X30MM Bolt x3 M4X10MM Bolt x2 M4 Nut x4 (x5 if using QD version of Stock End) M4X8MM Bolt x1 (if using QD version of Stock End) 2 part Epoxy(Araldite or similar) Notes 1: Parts on diagram with striped texture are points of contact that are glued. Side Rail Covers I have included these parts, but they are plain. I have included a file for the eagle logos too. (however i had trouble printing them and got some from shapeways instead: https://www.shapeways.com/product/CLWA9ZY2G/eagle2?optionId=62896387&li=shop-inventory) Sights I have drilled 2mm holes and set some tritium tubes into the sights. Very easy to do for night sites :)
