Riflescopes with Capped turrets

VIDEO

Introduction

There are plenty of possibilities when buying a rifle scope. Firstly, we have to ask ourselves why are we buying it. What is the main purpose of rifle scope we are looking for? When we define almost everything about our needs and try to determine the perfect scope, we still have to answer ourselves what kind of turrets should be the best option for us.

In this article, we are going to briefly discuss the most common turrets of them all – capped turrets.

Capped Turrets

Capped Turrets

Properties

These are the turrets that are being used as the most common choice on rifle scopes. In addition, hunting rifle scopes feature these turrets usually as standard option. Their advantage in hunting situations is that they are low profile. This also means that using them can avoid getting stuck or getting them hit in the bush, between tree branches or similar. They also do not get stuck somewhere on your clothes (pockets, zippers,...) during walking with rifle on your shoulder.

Also, the turrets stay protected under the caps from unintentional movement (adjusting clicks unwantedly). So, should capped turrets always be your decision when buying a hunting rifle scope? Of course, it depends whether the turrets have zero stop or not. For hunting situations, especially in thick terrain, I suggest at least zero stop function. If this function is not an option on your rifle scope, then classical capped turrets would probably be my preferred choice.

What is in common with all capped turrets, is the fact that they are usually only used when zeroing the rifle. Hunters who hunt on planes or mountains and are in need of having more versatile turrets because of easier bullet drop compensations and are also capable of taking longer shots at the same time, usually choose upgraded hunting rifle scopes with BDC (ballistic drop compensation) turrets. Such turrets are normally an upgrade on premium models of rifle scopes.

BDC turrets are probably quite popular nowadays, but majority of hunting rifle scopes still use standard capped turrets. In the past, these were the only form of turrets, found on rifle scopes.

It is important to know that target and tactical turrets can also be equipped with caps, but we shall not mistake them for classical capped turrets. Target and tactical turrets can both be used also without caps and still stay waterproof. However, target turrets are much higher and therefore they can be recognized immediately by their dimensions. If tactical turrets are capped, they are usually of single turn design (turrets are classified of how many times they can be rotated).

One of the important factors when buying a rifle scope are the ranges you plan to shoot at. If you know that most of your shots will be at short or medium ranges, usually there is no need for exposed turrets. If you are a long range hunter, you should probably consider the option with exposed turrets or at least BDC turrets with zero stop function.

Waterproofness of Rifle Scopes if caps are removed 

On majority of classic rifle scopes, the construction is not waterproof any more if the caps are removed. In most cases, there is a rubber O-ring seal on the thread of the caps. This O-ring seal keeps the water out when caps are tightened on the turrets. Waterproofness is the main property that makes difference between target, tactical and classical capped turrets. Target and tactical turrets (if equipped with caps) remain waterproof even when caps are removed from the turrets.

Conclusion

Classical capped turrets are preferred choice for hunting rifle scopes and are available on the market ever since rifle scopes are being manufactured. The caps normally stay on these scopes until the rifle has to be zeroed or re-zeroed.

Otherwise, people are not taking them off, because they are not the most appropriate choice for adjusting clicks on daily basis. In normal use, caps are tightened to the rifle scope and their main purpose is protecting the turrets against dust, dirt, water and unintentional movement (applying clicks when not needed).

Capped turrets combine two advantages for most users that use their scopes mainly for everyday hunting. These turrets are at the same time the cheapest ones on the market and also the most appropriate choice for the majority of hunters because of their ergonomic features.

General features

As the name suggests, these riflescopes are incredibly compact, measuring up to 33 centimeters in length. They weigh below 1000 grams and have a lens diameter of somewhere between 32 and 50 mm.

As these fall into this category, they are equipped with tactical turrets and an FFP reticle (there are some exceptions). Commonly, they feature a MIL/MIL configuration. Even though these riflescopes are small and light, they are packed with tactical capabilities.

Models of firearms compact tactical riflescopes are mounted on

This type of riflescopes are often paired with two distinct groups of rifles:

  • Semi-auto rifles, chambered in .308 Win., 6.5 Creedmoor or similar
  • Light tactical bolt action rifles, chambered in .308 Win., 6.5 Creedmoor or similar

It is important to keep the weight at a minimum, which is why these rifles are compact and light. With such rifles, one can expect to shoot at a medium range. Shooting beyond 1000 meters is rare.

Even though riflescopes designed for these rifles fall into the same category, they are not all the same. There are two major groups that we will discuss below.

Compact tactical riflescopes for semi-auto rifles, chambered in .308 Win. or related products

Certain optical devices in this category are designed with the DMR field of use in mind. DMR stands for Designated Marksman Rifle. Unlike sniper rifles, DMRs are almost always semi-automatic rifles with a high rate of fire. A designated marksman (DM) usually covers a distance of 50–800 m. Several riflescopes in this category are designed with the DM's objectives in mind. A wide field of view is important since engaging targets at a close range is common. Since this type of shooting takes place during the day, having a daytime bright illumination is a must. Some are partially designed for the tactical concept called CQB (Close-Quarters Battle) – the lowest magnification of such riflescopes is often 2x or even lower. Some devices feature an adjustable parallax, others do not. It is not uncommon for a shooter to use a compact-tactical riflescope both on a semi-auto rifle chambered in .308 Win. and on an AR-type rifle chambered in .223. Even though not a rule, a MIL/MIL configuration is popular. FFP reticles are much more common than SFP ones.

Compact tactical riflescopes for tactical bolt action rifles

Some optics in this category are designed for certain light bolt-action rifles, predominantly chambered in .308 Win. or 6.5 Creedmoor and packed with tactical features (Remington 700 Police is a great example of such a rifle). The size is the most important factor – only a compact rifle does justice to a compact riflescope. These devices are heavier than the ones for semi-auto rifles but don't exceed the 1 kg mark. With a magnification up to 20x and a lens diameter no bigger than 50 mm, once can pull off a shot up to 1000 m of distance. These rifles can also be paired with full-size tactical riflescopes, but the priority of owning a light tactical rifle is keeping the weight of its accessories at a minimum. Having an illuminated reticle is important, but a weak illumination will do just fine. As the maximum magnification is 12x or higher, one can expect to have an adjustable parallax on such a device. Having lots of elevation range at disposal is crucial, so the riflescope's tube measures at least 30 mm in diameter. The majority of these optics are of the MIL/MIL configuration.

Weight of compact tactical scopes

Weight is an especially important factor for a semi-auto rifle – it has to be as light as possible. Riflescopes for bolt-action rifles can weigh as much as 1 kg. It is important to note that a compact size does not necessarily imply a low weight
