new hills pump mk 5

[tapps]

due to another lock down, i ordered a mk 5 hills pump, i have 2 x 300bar bottles, a 7 litre and a 3 litre out of test & low on air. the mk 5 is advertised as being 20% less effort needed to pump than the mk 4, time will tell, not tried it yet it's still in the box waiting to be assembled.and before you ask, no i'm not going to fill my air bottle's with it !!!!! RIFLE ONLY.
