SADLAK M14 Steel Scope Mount

Why we picked this one - Sadlak has been in the firearm game since the 1990s for producing military accessories for the M14 and M1A rifles, and it's one of the most durable and reliable products available on the market today.

m1a optic mount points of contact

The more points of contact the mount has on the rifle the more solid it is. This is why the SADLAK steel mount is highly recommended even though it's much more work to install because it provides up to 6 contact points including the set screws that tighten the dovetail clip guide key.

Compared to other cheap mounts with only 2 - 3 contact points, the SADLAK is hands down the most superior product.

  • 3 Hex Screws - 65 - 70 inch-lbs
  • 2 Set screws for Clip Guide Key - 25 - 30 inch-lbs
  • Clip guide screw - 30 - 35 inch lbs

This thing ain't moving!

    M1A Scope Mount FAQ 

    Is The Mount Centered To The Rifle Bore

    Often people forget the minor detail of centering the scope base mount to the bore of the rifle.

    If you don't do this correctly you will waste tons of ammo and no matter how much you try to zero the rifle it will have a horizontal offset.

    Compared to other cheap mounts like the AIMS, UTG mounts, the SADLAK gives the rifle way better alignment, tightness for accuracy.

    Is Added Weight Significant?

    The SADLAK and Springfield Armory base mounts are the most reliable options on the market. The SADLAK mount is the lightest for weighing just 0.57 lbs with full steel construction.

    The Springfield mount weighs about 1.2 lbs.

    Optimize Scope Mount Height With Cheek Riser

    M1A cheek riser

    The M1A stock right out of the box is typically very low, so having a tall mount while chin welding the rifle isn't the best.

    The key here is to balance the cheek weld with the sight height. In our experience, getting a $20 rifle cheek riser that elevates your cheek weld for just about 1.5 - 2" is optimal.

    Wrap up

    The Springfield Gen 4 M1A mount is by far the best for rock solid optic mounting from the company that makes the rifle.

    Th SADLAK Steel version is the next best one out there. It's a bit harder to install but with multiple contact points help with maintaining zero.
