I don't offer staked-on sights at all, due to their inherent tendency to loosen. I recommend cross-dovetail sights to my customers, like Novaks and the host of others that are available. Dovetailed sights are well secured and will not loosen over time. By the same token, you can always change your dovetail front sight down the road to a tritium, fiber optic, serrated target or anything else you'd like - not to mention varying heights. To machine a dovetail and install a front sight, I charge $45 for Heinie's and $55 for Novak's (sight not included). For the reasonable up-front cost and value of a good sighting system, I always encourage customers not to compromise in this department. If you have a rear sight to fit your GI dovetail, I won't even charge you to swap it out.
