Help in removing front trigger guard screw on my enfield no.4 mk1*

[jmoore]

Whilst this is an odd screw to seize, stuck screws aren't uncommon to find in the gunsmithing trade. If you've the padded vise jaws and a drill press, place a bit in the chuck , bear down on the screw and use either a strap wrench or some other torque multipler to attempt to turn the screw whilst it's secured. (Power disconnected to the press, please!) Generally best done with two people.

Another very effective option is to use a well fitting driver that can withstand rapid medium light blows from a hammer whilst the driver is exerting torque. Also generally best done with two people unless you have some Khyber Pass skills. This technique works wonders when properly executed, but can disasterous if not! I find it most often useful when working on old Browning A5s with their skinny screw slots that won't take a lot of brute twisting force. (Both of these techniques were taught to me many moons ago by a master rifle builder who has far more experience than I on high-end sporters with ultra fancy stocks.)

Impact screw driver and a sledge hammer ... (or maybe not).

Sledge hammer is too heavy. And the imact driver tends to jump out of the screw slot due to it's internal springs, I guess. But the concept itself isn't bad!
