Optics are an important part of a modern weapons system. Once derided as too fragile for general use, the last couple of decades in Iraq and Afghanistan have taught us that optics can survive day-to-day use and abuse. Even the Marine Corps, long enamored with iron sights, has seen the value of magnified optics and now provides them as a general issue item. Magnified optics (aka “scopes’) are now on AR-15 rifles of all types. From long-range precision rifles to hunting rifles to do-it-all, multi-purpose guns…even CQB-oriented rifles are now sometimes equipped with low-powered variable optics (LPVO). A scope can increase your hit potential by upping your accuracy. A scope can also make it easier to observe the target – a good thing whether you are a tactical shooter or hunter. All of SOTA Arms’ AR-15s are equipped with a flattop upper for ease of mounting an optic. Mounting a scope can be a little tricky, though. Today we are going to take a look at mounting a scope, including choosing your scope and mount, what tools you need, and the actual mounting. Let’s get into it! Types of Scopes and Mounts It should probably go without saying, but before you begin mounting your rifle scope you will obviously want to choose your scope. The rifle’s application will have a lot to do with that; it wouldn’t make much sense to put a 12-power scope with a huge objective lens on a 10.5” AR pistol. It also probably wouldn’t be fitting to put an LPVO on a 24-inch varmint rifle. It’s up to you to know your rifle’s purpose and choose a scope accordingly, but there is a quick rundown of the most common types of scopes. Red Dot Optics: Though not actually telescoping and not technically “scopes,” this is perhaps the most common type of optic for AR-15 rifles. These optics are 1-power or zero magnification and are meant for fast, close-in work. Mounting these is simple as they already have a built-in mounting base that attaches to a Picatinny rail. Uses for Red Dots: Home defense rifles, CQB carbines, short-range hunting. Low-Powered Variable Optics (LPVO): This type of optic typically has a very low magnification setting, typically 1x (zero magnification) or 1.5x for fast, close work, and features rapidly changeable magnification up to about 4x or 6x. These scopes are incredibly versatile and are rapidly gaining popularity as the tactical scope du jour. The LPVO offers maximum versatility. Uses for LPVO: Patrol rifles, do-it-all rifles, brush guns, and general-purpose tactical rifles. Traditional Riflescopes: Traditional riflescopes come in either fixed or variable power and usually offer higher magnification. Variable-power scopes are very popular today, on everything from ARs to bolt-action rifles, with 3x-9x being the typical range of magnification. These do have the disadvantage of larger lenses, meaning they must be mounted higher above the rifle’s bore. Uses for Traditional Riflescopes: Hunting, long-range target shooting, tactical marksmen. Your purpose for having a scope will largely dictate the type of scope you choose. Another guiding factor will be the cost, but there are options ranging from affordable to top-of-the-line in all of these categories. There are also several other categories of niche scopes, but these are the mainstays. Types of Mounts Since you can’t mount a scope without mounts, let’s look at them too. The different types of optics mentioned above take different types of mounts. You don’t have to go all-out pricewise to get a decent mount, but you should buy quality; if your scope isn’t securely mounted your accuracy will suffer. As mentioned, most red-dot optics have a built-in mount and nothing more is required. LPVO optics often mount in what is known as a “one piece” mount. These mounts consist of a solid, one-piece base that includes the bottom halves of the scope rings built in. The basic steps to using a one-piece mount are to first mount it to the rifle’s rail and remove the top rings. Then scope is set in the bottom piece, and the top halves of the rings are placed over it and tightened, securing the optic. One-piece mounts range in price from $50 to close to ten times that. Traditional riflescopes usually mount in scope rings. These are rings that clamp around the scope, one near the objective lens, and one near the ocular lens (the lens closest to the shooter’s eye). Scope rings are typically two-piece affairs with a bottom portion that mounts to the gun’s rail or scope mount, and a top portion that secures the scope. One important factor when choosing scope rings is the diameter of the scope’s tube. This number is usually expressed in millimeters with 30mm and 40mm tubes being very common. Make sure you choose rings that match your scope. Tools You Need for Scope Mounting You will need some tools to mount your scope. Having the right tools will make the mounting process go much more smoothly. · Gun Vice: You need something to hold your AR platform during the mounting process. It should be stable, and it should hold the gun level. · Torque Wrench: you need to tighten screws to fairly precise in-lb measurements, not just “finger tight.” · Bubble Level: if your scope is not level your adjustments won’t correlate to real-world impact. A level is necessary to level your scope so that the reticle is a truly vertical line bisected by a truly horizontal line. · Thread Locker for locking screws in place. How to Mount a Scope
