I have a Bren 805 S1 pistol converted into a carbine by adding a barrel extension, by pinning and welding it. Never shot I as a pistol. I am having all kinds of accuracy problems, which I think may be stemming from the barrel extension affecting barrel dynamics. No signs of bullet strike on the extension. With the same ammo, my LaRue AR gets easily half the group size or better, both shot at 4x magnification.
Since I have purchased a 16 inch barrel from CZ-USA, I would like to use it and see if my accuracy would improve.
Are there any tutorials/Videos out there? Any help would be great!
Thank you.
