jgsa58,short carbine version of l1a1 rifle.very hard to find these nowadays.does have ebb but i took it off day 1 to save stress on the gearbox,i do have the part to put back in to make ebb work again.rifle in good working order and comes with x2 hicap mags.only thing missing from it is the little catch that releases the hop up cover when locked back but still can be released by pulling down on the bolt release.this was missing from the day i recieved it from the shop and they never sent another one hence the low price.gun still shoots well as only used once and has been on display since.collection from woodbury nr exeter or post at buyers cost..
