Like some other folks, I would like an option to put a peep on the receiver of the PC Carbine rather than using the factory peep mounted on the barrel. This would nearly double the sight radius between front and rear sight. Unfortunately as far as I can tell, with the factory front sight height a receiver mounted peep would need to be only about 1/4" above the surface of the rail. I know of only one peep sight that mounts that low, made by New England Custom Guns.
Besides being a little expensive ($99), the body looks like it would block the shooter's view around the peep and so not have the quick acquisition feature of a regular peep. Any alternatives that I've seen would require a taller front sight, and I have not been able to find anybody that makes one.
I did find a company that makes a short rail that replaces the front sight and has its upper plane on the same level as the receiver rail, made by TACCOM, only $20. https://taccom3g.com/product/front-sight-rail-for-ruger-pc-carbine/ That plus an ordinary set of Back Up Iron Sights (BUIS) and I have this:
The front sight winds up being a bit chunky but it's okay. I personally like the higher placement, I don't have to scrunch my fat face down against the stock so hard as I do with the factory sights. Removing and replacing the barrel doesn't seem to significantly effect the point of impact. All targets shown have a 1" grid, regardless of the size of the aiming diamond.
I was going to remove the BUIS and front rail and reinstall the factory front sight and compare groupings, but I didn't have the right size driver bit with me for the mounting screws. Maybe next time. I did put a target out at 60 yards and shot groups with a scope (mounted on QD risers) and the BUIS. Pretty comparable.
