A&K SR25 Redline N7 Milsim HPA. UPDATE. I’m now considering the break up of the Redline HPA parts from the gun body. What comes with the Redline HPA Kit... N7 for M4 $355 N7 Milsim kit $65 A&K SR25Gear box shell $35 Grip connect $24 N7 SR25 nozzle $23 Redline firebase Regulator an remote line $150 Retail total for just the HPA parts is $652 Asking $500 with free shipping CONUS Original N7 trigger board, FCU, FCU connector and solenoid are unused and still sealed in original packaging. The N7 milsim kit and the N7 engine have at most 8,000 rounds through them. The fire base regulator and remote line are used and show wear but fully functional. The only thing I’d remove from the above list would be the regulator and remote line. All the rest has to go as one package. I don’t need Redline parts. NO TRADES. No parting. The Redline kit was purchased as the regular HPA kit...so M4 nozzle comes with it...the trigger board and FCU are there....the original solenoid is there. The gat is configured with the Redline Milsim kit. So you have the option to use the engine in other V2 guns. Prowin hop. S-hop barrel. Gun is in great shape. Fielded only a few times. Comes with 9 A&K mid Caps. BIpod. Fore grip. Dust cover spring is reversed so it just needs pulled down to adjust hop. Charging handle is inoperative but can be freed up from the silicone holding in place...I can’t stand rattling charging handles. I have all the parts for the charging handle except the internal mock bolt thing. But I will include another one to see if you can use it. I am not satisfied with its distance. I worked on it some but have been distracted. The lower has been tapped to align the Nozzle. That works great. I’m just not happy with the Barrel / hop / bucking set up. Take some time and give it the attention it needs and it’ll be a game stopper. I will add an EDGI 550mm for $30. It has an extended hop window. $25 shipping CONUS.
