Been playin' around with this thing a bit... Am I missing a push-button on the Matech BUIS or is it just manually flipped up?
Re: the front site... while it has no hard "click" going to either position it definitely has a detent in there that provides a solid lock up and down. I wouldn't worry about it falling by any means. In fact its pretty tough to manipulate either way.
The stock body is a little looser on the tube than I like and there's a bit more flashing on the receiver around the trigger than my previous Colts.
The monolithic rail is rock solid. I'd love to see one of these with a 10.5" barrel.... possibly even with the standard A2 front sight set-up.
Does the 6940 accept standard barrels? I'm thinking about SBR'ing it and putting on an LMT or similar short barrel.
We shall see.........
