[merlin]

HI, well ive just gone out and bought myself this rifle in walnut....one awesome piece of kit !.....thing is the plastic plenum thing really dos'nt seem to be doing much to quieten it down...
so whats the best silencer for it ?....the air arms one looks good but i here the logun unit is the best....will it fit and is it any good for this rifle?.....any others i should consider ?

quick b4 i start p**ssing the neighbours off....lol

edit. forgot to say will it add any un-wanted power to the rifle?

thx in advance, Paul.
p.s. its a .22 if that helps...

A silencer shouldn't add an muzzle energy, however note that in a spring rifle a lot of the noise comes from the internal movement of the piston as opposed to the muzzle blast, there's little you can do to eliminate the latter.
