Peep sights aren't exactly cutting edge these days but I grew up using them and they are still very effective sights. Even with 64 year old eyes I can keep a 200 yard gong clanging about every shot from the kneeling position, as long as I wear my glasses and the barrel is long enough to get the front sight out there a bit.
They still use peep sights in matches out to 1000 yards - obviously ones a bit more sophisticated than this Skinner, but basically as long as you can distinguish the target you can hit it with a peep sight.
I'd love to see someone make a quality, rugged steel sight with click adjustments about the size of this or a Williams guide that fits on top of receivers in the scope mount holes, but it would necessarily be kind of expensive and probably not have the widest market.
Anyway, hope this was helpful to folks looking for a good useful peep.
One mistake in the original post is that the aperture center is .9285" above the bore, not .985". No biggie but I hate to make typos like that in technical details.
