Things To Consider Before Buying One-Piece Scope Mounts

One-piece mounts are great when it comes to installing a quality scope on AR 15 rifles. Besides adding height to the scope for proper visual relief, such an optic mount also pushes the scope forward over the precision rifle. Thus allowing longer scopes to be placed in a proper position to give you a comfortable vision. And the best part is that these scope mounts are aligned automatically.

But, certain factors can help you judge what kind of single piece mounts you need for your rifle. Also, these will help you pick out the best mounts in the market. Given below are all the aspects you need to consider while looking for a single piece mount:


1 piece optic mounts could be quite heavy. Actually, they are much heavier than the two-piece scope rings. And while choosing gear for your firearms, every single ounce matters because most hunters prefer carrying their guns and gear strapped to themselves. So, make sure that the mount you choose does not weigh too much and also if you are comfortable carrying the weight.


Scope-mounts provide the required height at which the rifle scope should be placed to ensure optimum eye relief. Incorrect height of the scope would result in strained eyes and distorted aim. There would be chances of making errors and so, the shooting experience would be ruined.


The durability and strength of the scope mount is yet another factor you need to analyze. While shooting, the gun could experience heavy recoils. And if the mount is not of superior construction, then chances are that it would break or strip off while firing. So, you need to ensure that the mount is built of strong elements like aircraft-grade aluminum, 661 t6 aluminum, or steel that can hold zero even after several rounds of firing.


A secure and tight fit is yet another necessary quality you want with your mounts. The entire mounting system should be held tightly in place. While firing rounds, the mount is bound to experience the recoil force and it should be able to bear that. If the fit is not strong enough, then soon the mount will loosen and the whole purpose of installing a scope will go in vain.


You could also consider buying a cantilever scope mount. The difference between a cantilever scope mount and a regular mount is that the former has its scope rings pushed forward by some distance. This overcomes the problem of uncomfortable vision that you might face sometimes with the red dot scope. So, leaving some inches before the rings can allow you some space to install a magnifier.

Moreover, the center of balance of the rifle will also change and that will improve your aiming accuracy. And, as we mentioned earlier, your field of view also gets enhanced since the scope will appear a bit smaller in the long-range.

6.Chamber Clearance

There are not many disadvantages with the single mount scope rings, but one of these include chamber clearance issues when these are mounted on bolt action rifles. When such a mount is used with a bolt action gun, the hunter might face discomfort while clearing out malfunctions and also while loading single rounds. So, if you want to use a bolt action gun, then perhaps a single piece mount isn’t the right choice for you.


Scopes are used for magnifying the target that gives you better aim while firing shots. So, these increase your shooting accuracy and range. And to hold these in position, you need proper mounts. Now, there are several kinds of mounts and we have discussed the top 5 single piece mounts in this blog. Such mounting systems offer easy installation, automatic alignment, proper visual relief, and much more. Hopefully, you have found what you were looking for.
