On its Facebook profile, Amoeba promotes an adjustable stock for spring powered Amoeba Striker S1/S2 rifles. The product is made of black plastic and has a height-adjustable cheekpad and an adjustable buttplate.
The attached poster also shows that it is possible to rotate the stock around the barrel axis by 360 degrees. What for? We have no idea. Bu we don't think its for unscrewing the rear part of the stock.
The accessory is marked as "limited edition" and currently priced at 80 USD. The regular price was 10 USD higher.
