I've seen posts some time back the some people were in the process of perfecting one. Any progress? Rock47, how's it coming for you? Dahun

Hey Rock, Any progress on that bolt hold open? It's been a while... I know it takes long, it took me 2 years to come to the final design. Keep us posted. Dahun

How is the work on this going? Have a movie clip yet? I'm anctious to see one, maybe your solution is the ticket. Dahun

Well, it is not "simple" but in order to achieve my goal, this is the simplest I know how. Goal was to provide: a last round bolt hold-open, with external thumb release, not interfere with the normal operation of the rifle, if it were to fail it should not interfere with the operation of the rifle, easy installation by most anyone, good quality materials (and durability) low cost. I think I achieved all my goals. As to the individual solutions, those are in most cases are subjective, relative to what you think is easy, simple, etc... Also, some compromises had to be made so t

Got anything that you could share with us? I'm curious about the features if not the mechanism. Later, Dahun

When will you have the video of the prototype in action? Dahun

Most of us have done it ourselves 'cause remember, you cannot just install a pistol grip, but you'd also have to reconfigure the trigger guard and the FCG. And depending on the state you're in, some gunsmiths won't eve mess with it due to BATF regulations. Your best bet is to do it yourself, with the help of the members on this board. Good Luck, Dahun

Excellent! Maybe you've solved an age old problem... Hope it works! Dahun

I'd like to see pics. Post them, 'cause I'm curious! Good luck, Dahun

Good ideas... and I have been considering them. I have thought of the drop in feature, but again money and space were at a premium. There is not much room inside next/between the trigger and hammer with springs and wires and such. ALso, the catch hat do be anchored somewhere where the receiver would be able to take the punishment. THis also dictated the geometry. Again, the magazine only moves about .07" from last round to empty, so that too had to be a big factor and had to multiply that by about 3x-4x to actuate the catch. Trust me, it took a big leap of faith (in myself) to strart dri

Rock47, Thanks for the input! Actually, this is the third and final prototype and I'm getting ready to send samples to a few magazines for their review. The one that's installed on my rifle has worked beautifully. Your note regarding the magazine mod. is well taken. My only problem has been the ability of sensing the bump, tab, etc. on the mag. follower. As you know, most bolt catch mechanisms are operated from a notch, recess, or hole in the mag. housing, and not through the magazine opening. Also, the AK magazines are pretty tight in that area. Another consideration was the proximity of

I've designed a true bolt-hold open device for the AK rifles. Currently offered for 7.62 Cal, rifles with double stack magazines. Please visit the site for more info. AK bolt catch.... Leave feedback in any case... Thanks, Dahun

Hi, guys... I'm the guy you mentioned in your mail. Thought I'd chime in. I have thought of the safety lever mod. with one difference. Why not cut the slot on the lever so that it's shaped more like a parallelogram with the vertical cuts slanted to the rear. You get two things from this. The bolt will stay engaged by the lever by virtue of the cam action, and when you pull back on the bolt, the lever tends to ride away from the charging handle and disengage the safety. I'll try attaching a modfied picture... Just a thought...

RSA has a write-up.... Don't know about the pistol grip tho... Dahun
