You talking about leverarmsdot.com? None are listed on the web site.
I have seen parts for the k98 but no parts for other models. Is this an issue? I wanted a scope but the stripper clip wouldn't work than and most don't have scopes. Don't think these guns and scopes are the thing!
I ended up getting a rear sight scope mount. Pretty easy instructions and it requires a scout scope. In cheapest to most expensive for scopes I’ve looked at NCSTAR, AIM PRO, and Vortex. Because of my inexperience with scopes I went cheap with NCSTAR and it works pretty well. Eventually I will upgrade the scope once I figure them out a bit more.
