I love the look of these rifles - definitely on The List for when I make it to the States.
I assume the gap between the grip and the trigger is due to using a grip meant for an AR?
You are correct.
I've come up with my own gap filler, and I'll be testing it out soon.
Feel free to contact me when you return - stay safe.
Please note that the B.U.I.S. experiment posted above, was just that.
I only wanted to test my theory to see if it would work or not.
