This is a custom designed laser sintered nylon adapter that allows you to use HPA (high pressure air) and Echo1/Cyma MP5 AEG magazines on your Hi-Capa airsoft pistol. To use it you will also need an MP5 AEG magazine, “paintball” tank with low pressure regulator (0-140) psi, a hose with a Foster (polarstar) quick disconnect and of course bbs. The normal operating pressure for green gas is roughly 120 psi depending on the temperature. We recommend that you run you pistol near this pressure and do not exceed 140 psi. Keep in mind that higher pressures can cause excessive wear and damage to the internal components of your airsoft pistol.

There are 2 versions of this adapter. One for WE tech / Armorer Works mags and one version for Tokyo Marui mags. You will need to install the adapter onto a 5.1 magazine which is the one with the long baseplate. The adapter will not fit onto a WE tech 4.3 magazine with the short baseplate. The adapter will fit into a 4.3 Hi-capa with a 5.1 magazine because the grip is the same on both 5.1 and 4.3 Hi-Capas.  The TM version adapter is the one with the long bb feed tube that prevents jamming from double stacking. The metal quick disconnect fitting in the photos will come installed. The fitting is a US standard Foster Pneumatics 1/8 NPT quick disconnect. The fitting can be changed to any fitting that has 1/8 NPT threads. Be sure not to cross thread the fitting when installing a different one. The adapter does not come with a gun, magazine or any other accessories. The plastic spacer can be used to short stroke your slide if you choose to use it. 

For the most consistent reliability we recommend you use the Echo1/Cyma 110 round straight MP5 magazines. It also works with MP5 drum mags and curved MP5 mags but they look funny.

Amazing people, I bought a awesome rifle CM16 Raider Black and a 1911 .45 STI, both are incredible weapons.

Still remains to be the best field in New England. Great selection at the pro shop. They also have online shopping with shipping and store pick up options available. Great admission price and large adaptable field. Perfect for experienced and new players with rental packages available. Unfortunately I wish they have more weekday games available as they are usually only open to airsoft session on weekends but the store will still remain open for your shopping needs. Not to mention they fix and buy used airsoft guns.

Very nice staff, had everything I needed. I would definitely recommend this place to any airsoft players. They have a great field, and overall a great community. They gave advice as what direction to head next with some of my guns and helped me fix issues with my arp9. They had everything I needed in stock for the arp9 and my other guns. Recommend 6/5 stars.
