Selling this as I have given up on HPA after realising it wasn't for me. It's been fitted with a polarstar kythera and the correct nozzle for this model (#13). The hop up chamber is a ZCI polymer so I could fit a 4UAD bucking and nub inside. It also has a ZCI barrel inside, can't remember length but is same as original. The kythera was fitted with the amped IGL and running out of the stock grip which has been modified so it will feed through. The fire selector is non-functional as is the bolt catch. Minor wear and tear on the outside mainly on the handguard as seen in photos. 3 nuprol magazines are included as is the original. A video of it firing or additional pictures can be provided on request. Price is £380 inc postage anywhere in the UK, to buy everything new would cost upwards of £600 exc labour.
