I’ve got my Dad’s old U9 Herters varmit rifle in 222 rem mag and I’m looking for a one piece picatinny rail and I’ve read that one that would work for a Howa 1500 SA will work. Do any of yall have any experience with these rifles or know where I can find out for sure. I’m pretty sure that the 2 piece mount is the same as a weaver #36 back and weaver #40 front mount any information would be greatly appreciated. I pray that y’all have a blessed weekend
