SpeedQB RedfrostCustoms Upper

cults3d

This is my very first upper to be made! The platform that this is fitted for is a G&G receiver! Please note that you will need a cut gearbox or an Airtac gearbox! I have also only tested it with MAXX hopups! Added design for AEG/uncut gearboxes! Added design for 128mm inners Added design for 155mm inners Added Clean design for upper part (no cuts) Added compatibility for G&G Gen2 recivers Added Clean design for AEG/uncut gearboxes Two M3 screws will be needed (works super with the grip screws from the M4 grips) The design I have made is for 128mm and 155mm inner barrels. Thanks to my "brilliant" 2 piece design the barrel part of the upper is changeable so if you mess up the threads or bang it into a wall at full speed you just need to take out 2 screws and slide on another barrel! Personally after testing and playing with the upper i am impressed by the strength of it. I have probably put in about 30 or so SpeedQB games with it and i have had zero issues! If you want any custom designs don't be afraid to send me a message! Please note the copyright for this design belongs to me and this design may not be sold or distributed from third-partys!
