The greatest advantage of a low-power variable magnification scope is having the capability to both engage close-quarters targets at red dot speeds without sacrificing your ability to reach out and touch targets that might present themselves at extended ranges. Really drive that advantage home with the Primary Arms Mag-Tight® Magnification Lever! Precision machined from lightweight aluminum to perfectly fit the popular SLx line of LPVOs, the Mag-Tight® Magnification Lever allows shooters to quickly and confidently shift through their magnification range and even quickly gauge their current setting. Each lever is finished with a tough hardcoat anodized finish to offer a lifetime of service.


  • Lightweight, yet sturdy construction
  • Precision CNC machined from 6061-T6 aluminum
  • Extended lever for fast magnification changes
  • Tough black Type III hardcoat anodized finish

Nice work

by -

Sturdy,well made just like the scopes. Mounted very easily works great

PA does good things.

Seriously. You like being a tacticool operator with quick zooms? High speed low drag? This is it. This makes switching power too easy and fun.

Great Addition


Fits great. Looks great. Works great. Engineered very well.

Does Not Fit the 3-18 ACSS HUD


Look like a solid product, unfortunately it doesnt fit on my PA 3-18 ACSS HUD scope. BUT thats my fault, it clearly says in the description what models it works with but i thought id give it a try anyway and I learned the hard way! Wish PA made one for their other scopes.

Definitely get it


So much quicker to change magnification, feels really nice. Enough to grab but not enough to snag. 10/10

A welcome addition to my LPVO

by -

Added this to my PA 1-6x and haven't looked back since. It's just such a convenient addition for the cost, especially so when shooting with gloves. I'll be adding this to any future PA scope orders.

Perfectly Great

This throw lever fits& functions flawlessly!

It gets your "POINT" across!

by -

Best accessory for an LPVO you can buy. This helps you go from 1 to 6 or 1 to 8 very quickly. Sometimes the shift nob is short on your scope when you get/buy it....USE THIS!

Well, the process was good...

by -

Ordered it not not paying attention that it was only for the sLX line. The return process worked out well though. Good on PA for working with my mistake.

Does NOT fit entire SLX LPVO line (no fit on FFP)

by -

As of 4/19/21: Description says it fits SLX LPVO line, but does NOT list the SLX FFP models as exclusions to what it fits. If you have an FFP, this will not work for you. Primary Arms does not sell a throw lever for you, you'll have to find one somewhere else.

It was good to speak to you on this issue. Please let us know if we can help you with anything
