WTS / WTT Krytac SPR w/ engine installed The item in question is a Krytac SPR with a Redline N7 MilSim unit installed. (Install performed by Airsoft Junkiez, the bolt catch and ambidextrous selector lever is functional) In addition there is a Umbrella Armoury 383mm 6.03mm tight bore barrel that has been R-Hopped with a custom bucking and nub, which is housed in a Prowin hopup. Fewer than 2k rounds have been shot through this system, and it performed impeccably at MilSim West's Balkar Ridge. The only item of note is that being a mechanical system (no batteries, plug and go), there is no full auto capability, and if you hammer the semi really fast you will have double feeds. $550 OBO, I prefer PayPal. The only trades I'm interested in at this moment is a Gen 2 E&L AK 74 with synthetic furniture.
