| I have an M4 and am looking for a heavy hammer spring so I can use my 5.45 x 39 upper with it cheap ammo is why. Yes, I know it is corrosive, but I enjoy shootin it full and burst so much that I can olny afford the cheap ammo. The only problem is the burst hammer springs in the appropriate strength are no were to be found. I have a bunch of the hammer springs for the AR, but they will not work because the buirst spring is larger on one side to go around the ratchet for the burst count. Anyone out there know where to get a heavy weight burst hammer spring? |
