Hi guys, here i build that prototype of a mask friendly stock installed on my TMC. With a different front mount it would fit to most other markers too, i´m shure ! So cause it´s Protype etc. it´s not painted flat black and i also like to use for front install a bolt which goes through the hole of the pin which holds the original stock. Fell´s good, got less weight and fits perfect. So it´s getting close to real Feeling of having face on a real stock !!! May this is something for someone ??? But i think i don´t finish this cause i use my tank stock for low paint waste and i´m not the remote line guy !!!
