If you’re after a CA M15 you are in luck as according to John at EliteAirsoft they’ve just got a shipment of M15 Tac Carbines, which was somewhat of a surprise to them:
Bargain of the Month:
We have 15 Classic Army M15A4 Tac Carbines delivered mistakenly. Rather than
send ’em back we will pass these on at unbelievable prices.Until stocks go, these beauties are available for the pitiful sum of £210
delivered to your door.We don’t think they will last too long at that price, so please come back
soon. John, (EliteAirsoft)
