Mito Hammer spring replacement

After trying various spring sizes i found a workable solution for the poor hammer spring fitted to the Mito , We have taken feedback on board and sourced an even better alternate ,there is very little room for change due to compression distance of spring (without machining the hammer itself) and due to trigger lock in position on the hammer, so the correct calibre 65n/m spring is very crucial , have a look at the video below or get in touch, they are for sale via the link button, like wise you will need a chronograph once installed "x3006 vocal" is the best option, we supply these with the 3D print 1/2" screw on adapter already installed to the chronograph to suit Reximex varients see photo below, The vocal read out is most useful when testing your weapon and significantly improves quick setup times.

web site Offer -Free hammer spring and safety screw replacement included if you purchase the Chronograph simply drop a note on purchase

Reximex Mito Valve Stem – Updated Version

New improved style valve stem for the Reximex Mito air pistol.
Fitted as standard to UK Mito models from 2025 and over.

Retrofittable to earlier versions – replaces old valve stem and the valve seat – now seals directly to the action.
If fitting to an older version with valve seat you will need to remove the old valve seat before installing – this generally will release by gentle hammer tap on firing pin from hammer end, failing that a wood screw can be used to pull it free

Scope Selection

Tried quite a few scopes and red dots The Mito is very capable as a carbine at 30-40 yards so a scope was eventually chosen, if you can stand the size of the Diana this was the best/cheapest option, a good scope at about £45 - its a bargain, The Vector optics Cerato sits better on the Mito as its a smaller size compact at about £79 affordable but after a period of use little flaws appeared so the discovery was eventually chosen but more expensive ! at about £130 Prices for these vary all over after some more testing we have found the perfect scope match for the Mito affordable at £65 too have a look in our store for more info on this lovely 190mm compact 3-9x40 scope complete with mounting rings

Display Signs

We also have a laser custom sign facility so if you are looking for a illuminated LED acrylic display sign above your weapon please contact us below, i will collect your requirement and send back a proof of the design before machining, these signs can be provided in multiple mount formats with standard concealed hangers on rear or alternately we can provide stud fixings 2/4 for a small extra charge.be aware that The signs also act as down or up illuminators and can be used to enhance your weapon if wall mounted , the illustrated sign is a down lighter casting blue/white light to the floor or onto weapon but this can be reversed
