There is no Bullpup available at present - this was a prototype and there are non available - although with enough interest it could be made available again.
I am afraid there are no MK-300 target (or sniper) available at present - all our stock is sold, and some modifications have delayed new batch being ready. Floating barrel will be an option on new model if requested.
As a note, all out prices are max you will pay from local dealer - if sent from Sure Shot Airguns direct, RFD collection fee and postage is included in the price. If you want to visit us to collect then good discounts should be available.
