This was a website accessory until recently...no provision for iron sights, just drilled and tapped for a rail.
Any place to still find one? Any members want to get rid of one?
I'm not interested in an aftermarket barrel (like Clark, and others)...my understanding is the factory "optics only" was an attempt to salvage barrels that had been manufactured incorrectly, and they were shortened and never dovetailed for rear sight, and front sight was removed by shortening barrel.
Used is OK, with worn bluing, if price is right, and good bore.
Will be mainly used as a squirrel-gun, and will get additional field wear anyhow.
I want to keep my original iron-sight barrel as-is, and want a separate one for a red-dot.
