Hello all Impact M4, M3, MkII, X & MkI owners:
I stopped selling these FX Impact stainless steel bolt sets awhile ago but since the release of the M4, several members have contacted me about getting a set for their new rifle - so I've brought them back and have updated the kits to include the latest M4 model!!! These kits will replace pretty much all of the visible screws (and also some of the partially hidden ones like the ones on the scope rail and guiding plate) on the Impact MkI, X, MkII, M3 and M4. These stainless steel bolts will wear better and won't rust over time; it's also an inexpensive way to add a nice bit of flash and contrast to the rifle.
Each kit will come with the bolts separated in labeled bags, anti-seize compound and a spreadsheet with installation notes. The schematic and parts list for each model can be found here:
