A Great Sight For Tired Old Eyes

by Legacy Reviewer, Verified Owner from United States, LA Written on July 27, 2013
I just purchased my second Lyman 57GPR receiver sight and now have one of a .54 caliber GPR and one on a .50 caliber GPR. These sights move the distance at which I can accurately place a shot from 50 yards to 100+ yards. They are so easy to mount and adjust that I wouldn't consider any other sight for a GPR. It's even better than two of the other sights I've used and liked - the Thompson Center Tang Mouted Peep sight and the no longer available TC Vernier sight.
Pros: This sight doubled the range at which I can confidently shoot.
Cons: A bit bulky. But the great featues require a little bulk....

Great Sight!

by Legacy Reviewer, from United States, WA Written on January 19, 2013
This is what I needed to make my flintlock shoot-able again. At age 61, my eyes need a little help and the aperture sight makes it happen. I should have put one of these on years ago!...

Lyman Peep Sight for Great Plaines Black Powder Rifle

by Legacy Reviewer, Verified Owner Written on January 13, 2013
I personally would like Target Knobs for windage and elevation. Rifle stock Length of pull is a tad short, Lyman should manufacture a stock extension as an accessory. Remember to swab attachment screw holes with alcohol, wipe dry with cue-tips, and use a product like "Loc Tite" to secure screws.
Pros: Well made.
Cons: None....

Lyman 57SML Rear Sight 3090114

by Legacy Reviewer, Verified Owner from United States, CO Written on December 17, 2011
This sight helped tighten my shot group tremendously, you can't beat the simplicity and accuracy. Since it sits on the tang, you do have to mind where you place the thumb on your shooting hand. Colorado and some other states do not allow optics on muzzle loaders while hunting, but this sight is the next best thing to an optic. I would also recommend painting a high visibility dot on your front sight to make acquisition easier.
Pros: Easy to mount and set up
Cons: Takes some getting used to...
