The Ar-15 has a lot going for it. It’s light, it’s easy to mount an optic to, and the standard guns fire a cheap cartridge. So many people get an Ar-15 for their first rifle and go on to buy the best scope mount for an Ar-15 they can get and mate up good scope and call it a day!
However, you’re going to long for power. Meet, the m1a! It fires a full-size cartridge that can travel over three times the effective distance than the 5.56, and is a huge step up from a standard Ar-15 that is so popular.
Seasoned shooters know that the m1a is in many ways a superior full sized battle rifle and do the righteous chore of mounting a scope and stretching the rifle’s legs.
If you’re going to upgrade your m1a with a scope, you need to know a few things and you need to keep a few quirks about the m1a in mind. The m1a was designed as a close range, fast firing beast, simple medium power scopes like these 5 best 1-6x power scopes complement the rifle well.
Chiefly being the obstacle of the open action that ejects brass pretty much upward. The m1a was designed in a time when individual soldiers didn’t get optics unless they had a special duty. That means there’s just not a great way to mount an optic on an m1a unless you get creative.
There are mounts available for the m1a that raises the optic far enough to allow brass to be ejected from the receiver, but it also makes it impossible to have a cheek weld with the factory stock. You’ll either need a slip-on pad or shoot with a “chin weld.”
Of course, this mount style allows you to use a standard scope though, your other option is to mount the best scope for m1a further forward.
Scout Rifle Mount
Much like a scout rifle, you can mount a magnified optic designed with long eye relief on the picatinny rail section that comes from the factory with Springfield Armory rifles.
The Scout Rifle Mount gives a few distinct advantages over a traditional mount, more situational awareness, zero chance of scope bite, and an easier set up to shoot both eyes open with.
The downsides of the this set up being a steep learning curve, worse weapon balance, and your optic being more exposed when firing and moving around in the field. It’s very much a love or hate option. For many shooters, they’ll want the advantages these 5 best scout scopes provide.
Try and find a rifle with a forward mounted scope and shoot a box or two of ammunition through it before you commit to one.
