hey - any thoughts on making a non-reciprocating bolt handle system for the mcr and others? thoughts are that it could mount over the existing channel on the left side using the fastener openings for the steel plate (or drill/tap for earlier versions or the wk). just a thin plate with a slide similar to the r18; the bolt handle would engage the bcg for charging but not forward assist? have the bolt handle float a bit so installed alignment and tolerances don't need to be perfect? and if it could fold ...

My thought it would be less engineering to retrofit on a spring loaded charging handle cover, like that on the FN Fal, https://www.canadiangunnutz.com/forum/showthread.php/2212815-WK-MCR-spring-loaded-charging-track-dust-cover-possible-like-FN-FNC-Galil-ACE, or rubber lip charging slot cover for the handle to move through, like on the SIG MCX, https://www.canadiangunnutz.com/forum/showthread.php/2202824-Question-WK-MCR-Charging-Handle-Track-Rubber-Dust-Cover-like-SIG-556-Possible.

agreed. i'd buy that fnc part. it's a spring, a plate, and two fasteners. sell it with a bit, a tap, and a drilling template. i'd bet a lot would sell. it's a stamped plate but doesn't need to be; cut it out of some flat sheet and find an elegant way to affix the spring and manufacturing shouldn't be too difficult.

And if someone doesn't feel comfortable enough to do the work themselves, they can take it to a local gunsmith to have installed.

Make the drill template a 3D printed jig, easy enough

Hell, 3D print the cover itself. It shouldn't be under too much stress, and could be easily replaced if needed then. You would still of course need metal construction for the spring and fasteners. :p

pfft. tell that to companies that bring complete firearms to market after "160 rounds at the local CHAS range" for testing and then denigrate HK and B&T. as an engineer, not a lot of engineering is required to make a not-critical piece of metal go up and down. worst case? it goes up and does't come down. big deal.
