They wouldn’t. I just called Sig because I was suspicious that this is identical to the defunct Nikon. I was right. It’s the good old buckmaster. Best scope of all time if the quality stayed the same.
I would recommend extra-high scope rings, or any scope rings/mount with a centerline height of at least 1.44". For more information, email us at Techsales@opticsplanet.com.
The SIG SAUER Buckmasters 3-9x40mm Rifle Scope features a multi-caliber BDC reticle that will work fine with 350 Legend. The scope itself is shock and recoil proof. However, Sig Sauer does not specify an exact recoil rating. It should be fine with your AR15 in 350 Legend.
I would recommend using a dedicated AR15 style scope mount that elevates the eyepiece to a more comfortable shooting position on the AR platform. I would suggest using the Aero Precision Ultralight 1in Extended Scope Mount, found by using the link below:

The Sig Sauer Buckmasters 3-9x40mm Rifle Scope has a fixed parallax setting at 150 yards.
The SIG SAUER Buckmasters 3-9x40mm Rifle Scope will work with the Sig Buckmaster Rangefinder in order to help give you a holdover for the compatible 8 Ballistic groups. However, the SIG SAUER Buckmasters 3-9x40mm Rifle Scope is not BDX compatible where the Sig BDX rangefinders will Bluetooth sync to the scope. The 8 Ballistic groups with the Sig Buckmaster Rangefinder do not include .22LR.
The Sig Sauer Buckmasters 3-9x40mm Riflescope will work fine with a 22LR.
The Sig Sauer Buckmasters 3-9x40mm Riflescope does not come with a scope mount or rings.
if it handles 45-70 it will surely handle 7mm mag
holdovers on a 2nd focal plane scope only work on highest power setting, to be accurate,if you choose lower setting you will have to calculate holdover markings, your best bet is to buy the reticle scope that matches the cal you are shooting, .350, .450,
