Superlight Mag Trigger?
Last night my mind was inordantely fertile.... People were complaining about how the LX changed the feel of the trigger on a mag. IIRC Rob even put the L7 back into his classic mag becuase he prefered it's feel.
Let me set the scene. For this to work, it requires a properly setup LX. And it will require a new bolt and sear for any of this to work. Ideally it would use a new on/off too.
The current mag bolt and sear is designed so that no matter how much force is on the mags bolt the sear will still hold. Its a locking design for all intents and purposes. What if we used the bolt's force to our advantage? Like they do on a cocker. Setup the sear so that the bolts force trys to force the sear down. This force will ballance against the on/off making the trigger feel softer. And you won't be dragging the sear the whole way across the bolt, once you start it moving the shape of the bolt will help you move the sear.
Cockers have been like this for a very long time. They have a sear that's shaped so that just a breath of force on them will cause them to move across the sear lug and drop the hammer. And people good with cockers have known that changing the shape of the sear and lug would change the feel of the trigger pull on a cocker.... the same is true for a mag. Just the forces have been so high that I don't think it would have been a sane move untill the advent of the LX.
Here is my idea for making a mag's trigger much lighter. As it stands where the sear interface is a cone facing the back of the gun now, you'd have a cone that faced the front of the gun. And instead of a convex face on the sear, you'd need a concave one. Or you could even go a more conservative route and go with a flat bolt face and sear with a flat face as well.
Of course this leads to another idea. You could tune mag trigger feel with differnet angles and different shapes of the sear and bolt. Just like the cocker...
Becuase the bolt isn't locking, you'll probally want to time the mag more conservatively (aka longer on/off pin) And that would ensure that the bolt "locked up." A term that's not quite apropreate for a cone shaped bolt interface.
Picture one is the current bolt and sear setup. Picture two is a less radical design, but more prone to wear. Picture three is what i'm imagining. All of these are exagerated and not to scale, and don't show room for the boltspring, but the idea should come through.
