Good afternoon!
I am the commander of my local Young Marines unit, were a non profit youth group similar to the boy scouts. I'm going to start training them up for rifle competitions. I have access to a bunch of target style Co2 pellet guns for the younger ones, but I thought I'd get some of my older kids experience on a good rimfire. I have this cz457 laying around, but it needs irons.
I am looking for advice on attaching a front sight. If anyone has experience doing this, or has some suggestions on a preferred method, I'd appreciate any input.
So far I have considered cutting a dovetail directly into the barrel; making a slip-on ring with a dovetail sight base; drilling and tapping the barrel for screws; boring out an m1 carbine front sight to match barrel OD; making a 1/2-28 threaded collar with a dovetail on top to screw onto muzzle; silver soldering on a f.s.b
I know this isn't re inventing the wheel, but I thought I would ask here to avoid wasting a bunch of time on making something that wont work well in practice, or might ruin my barrel. For example, I thought making a front sight base that could thread onto the muzzle would be a great idea so I wouldn't have to risk cutting into the barrel & so I could take it off when Its nrl22 time. However, this doesn't seem to be a common method of attachment. There isn't much that comes up when you search for "thread-on front sight" etc etc, and maybe the reason for that is that its a stupid idea and doesn't work irl. Anyways. If you have thoughts or advice I'd appreciate it, just looking for a good direction to head in.

Call Champions Choice. Tell them what you have and what you want to do. They can give you guidance. The rear is going to be the most problematic. The front can use a clamp on base. Wialliams sights might have something also.
