HPA to M4 mag adaptor (M4 G&G hi-cap confirmed fit) turn your Beretta into a HPA speed soft gun perfect for CQB i decided to turn my beretta HPA since i had issues with my original mags leaking in summer on my belt. i barely got to play with it last season because of my mags would empty while in my pouches. this solves that issue with M4 mags. additional materials needed : - QD HPA adaptor (any model should fit. i used WE) - JB weld (for the fitting) - epoxy or crazy glue (to air seal the air channel) - black gasket maker (to seal the bottom of the pistol mag) - little spring for mag release i had to cut the little nipple from the bottom of my grip for the adaptor to sit properly. (the loop for a safety lanyard) the last picture provided is after cutting off the nipple process : - sealing the air channel : you'll need to pour some epoxy resin into the air channel to make sure to seal the layers. (i had previous issues with my print leaking air between layers) doesnt need to be a thick layer of epoxy, let it drip out while drying, scrap off the drips as drying goes and they form. **make sure you dont block the airway, blow air through during the whole process making sure not to block the airway itself** - degrease the bottom of the pistol mag, using the same o-ring, fit it to the adaptor, add some gasket maker to seal the mag and o-ring to the adaptor. (layer of gasket maker of the inside of the mag itself and a layer on the adaptor to make sure of a good bond/seal is created) -degrease the HPA fitting, use JB weld to secure the fitting in its hole. wait 48H to completly dry. i also had to add a small rectangle of plastic in the bottom of the mag to kep the bbs in the feeding channel.
