To answer your question .... YES ! It can be done , some say it can't due to the barrel being shorter but I say "have you done a conversion or just passing on stories"

Parts required are:-

12ftlb reg
12ftlb hammer & spring
Dominator probe /spring / rear spring clip
Either shorten the lever or buy an off set one

The only difference the 10m block and the dominator have is 10m rifles either have one of two systems fitted depending on the age this absorber comes out via the rear of the block (an Allen screw ) where as the dommi has a 10m hole for the probe to slide in and the rear spring clip to hold the spring in place

Barrel wise I've converted my lg300 and it shoots spot on one hole groups on a still day out to 50yds with a steady hand
