I emptied a box of 50 remington subs with no jams
50 RWS subs generated 3 'short strokes where the empty case was ejected afresh one chamberd but the hammer wasnt cocked. the gtouping was improved to less than a 10p peice at 25yds on rapid fire.
50 eley match grouped inside a 5p peice at 25yds with no failures to chamber or cycle the hammer but a couple of failed case ejects (nipped in behind the breech block and jammed the hammer).
the Winchester subs did the best overall with no failures and a nice consistent group
I'll continue trialing with a few more boxes and make sure its sorted.
Most importantly ...no light strikes in evidence

Looking promising

next job is to remove the flash hider and fit the SAK mod to see how quiet it is.

That Flash hider is on bloody tight! got the right size spanner on it and not a hint of thinking about moving
Only 15 years too late to the show, but the FAL is reverse twist thread for the flash hider!

I also have one of these in 22LR, a fixed stock version, serial 50008, it's a lovely rifle to shoot, do you still have yours?

Kind Regards
