I feel like a parrot because I've said the same thing in at least two other threads today, but I don't like the look of tech sights on a sporter style rifle. Tech sights are popular for a reason though, they're pretty good sights.
I can understand that viewpoint. However, to me, the 10/22 is far from a sleek, classic sporter in both design and appearance; I think it is has more of a para-military, M1/M1 Carbine look to it, and I feel the Tech Sights enhance that look, while offering a much improved sighting option :bthumb: Many complain that they are somewhat overpriced, and that may be (I have yet to try a set myself, but would like to at some point), but I have seen Williams receiver sights selling for more than the cost of the entire Tech Sight package
From what I have seen, Williams offerings are decent, but of varying quality and oftentimes are difficult to fit and sight in. I have had no real problems with the models I have used, but cannot say they are of particularly great quality. When you compare these to the Tech Sights, the price of the latter IMO, becomes quite reasonable indeed :bthumb:
I have been contemplating picking up another semi-auto .22, as my recently acquired Ted Williams 3T (aka Winchester 190) has been a big disappointment so far. The Marlin guns offer great value, and I am considering them, but am leaning more towards the Ruger currently - the fact that my favorite shop informed me that Ruger is the only brand of .22 auto rifles that he has had no common issues or returns may have helped sway me a bit

:t
Looking at the 10/22, it has rather decent iron sights right out of the box, unlike most .22s these days. I believe they are made by Marble's and should work OK; that said, there are many upgrades out there in this department, with the Tech Sights being one of the most popular it seems.
For a 'quick fix' I would think it would be no trouble to machine a piece of metal to match the rear plate in the stock rear sight, and drill an aperture in it. I, along with quite a few others, have used this technique on Henry rifles (and at least one Browning BL-22) with surprising success :t While the field of view and sighting radius are not as good as would be offered by a receiver mounted sight, this trick allows for much more accurate shooting than is possible with regular open sights :bthumb: :AR15firin
An additional advantage to the 'poor man's peep sight' is that it maintains the stock sight height, and should theoretically be much easier to sight in than most receiver mounted systems, which often require a taller front sight to get on target. If, like me, you are not mechanically inclined, you can always have someone who is whip something up; it takes little materials, time, or effort to accomplish and is definitely worthy of consideration IMO :bthumb: I had my gunsmith best friend create mine - it took about twenty minutes total, and that included fiddling with different 'aperture' sizes
Edit: here's a link that shows the type of sight I'm referring to:

Sorry for the rambling, and I hope the OP finds a peep sight that fits the bill :t
Kind Regards,
