lol again my question remains, what pin in the bolt catch are you refering to?
there is 1 pin to keep the 2 piece design together, so I assume you are refering to that big pin.
But without the pin the bolt catch would just fall off
so again, what pin are you refering too?
its not an M4, its a Scar....
And the bolt does not seem sluggish, its actually very smooth
It just doesnt go far enough back to engage the bolt catch.
And if it is not releasing enough gas, could this be due to simple cool down effect I wonder????
So nothing mechanical or technical, just cool down effect considering my descriptions above?
With every new fresh mag it works, but after a while it doesnt....
