Bought this for £675 prior to Covid and I’ve never been to Airsoft since so it’s unused.

Comes with 1 Tippman 13ci Tank (full)

Case is not included in the sale 

collection from Blackburn (Lancashire)

full spec:

The revolutionary AR-1 is a self-contained high pressure airsoft rifle. Truly the first of it's kind, this AR/M4 platform is ready to skirmish out of the box. With an included 13/3000 Tank/Stock combo there is no need for bulky bottles, remote lines, or even second stage regulators. AR-1 is truly 100% self-contained. The efficient mechanical system has a shot count of 600+ rounds per tank (13 cubic inches @3000psi). The body is made out of a high grade cast aluminum and is manufactured to the tightest tolerances. Featuring a robust valve system isolated from the striker/bolt assembly, the operator can separate the upper from the lower safely without the need to de-gas the system, i.e. remove the tank/air source.
