I am getting a Henry Frontier 22lr 24" and going to put a Lyman front globe sight and a Williams peep on it. My question is the Lyman 17 AHB ( .404 height ) correct w/ Williams FP-GR-TK peep for grooved reciever on this rifle . Thanks for your help.

My son has the 0.494" and it puts the rear sight close to the center of the adjustment range. I would start there, but individual rifles may vary.
