New Shotgun Magazine Tube Mounted Light Concept from Holosun

Holosun is testing the waters on a new shotgun weaponlight that mounts in line with the magazine tube. I suspect many shotgun users have dreamed about being able to mount a light on the end of the magazine tube over the years but switching for this light location has always been the fly in the ointment. The activation switch set up for this light has not been revealed at this time.

Review: V Seven Weapon Systems 10/22 20 CAL Barrel

The 10/22 20 CAL Barrels from V Seven Weapon Systems (V7) are pretty interesting to say the least. They offer excellent accuracy and make use of a tapered bore (or maybe some voodoo magic) to generate increased velocity and more energy down range.

Overview

These 416R stainless steel barrels are a direct drop-in replacement for your Ruger 10/22 rifle. They are available in a 16.1″ sporter profile (the subject of this review) and an 18″ bull barrel profile. Both barrels have a fluting option, feature a match chamber, threaded muzzle, and have oversized extractor pockets to ensure the extractor can move freely.

Both barrels also feature a relatively fast 1 in 10″ twist and a tapered bore that swages the projectile down from .22 caliber to .20 caliber. V7 claims that this feature leads to improved accuracy and reliability, increased ballistic coefficient (from reducing diameter and lengthening the projectile), and more energy down range. I actually saw a small but notable increase in velocity as well (more on that later).

Observations from Use

The barrel that I tested is the 16.1″, sporter profile version with fluting. I selected this barrel because, based on V7’s claims, I was hoping to use the barrel on my franken-22 to increase its effectiveness as a small game hunting and field rifle. My hope was that I could increase accuracy, increase range, and reduce the overall weight of my rifle just by replacing the barrel… and it worked.

There are some bold claims associated with these barrels and I wanted to test them to the extent that I could. I first installed the barrel on a rifle that has become an absolute mish-mash of parts over the years. It has a Weaver 2.5-7×28 Rimfire scope mounted to a mostly original 10/22 receiver and action. The rifle is full of various other replacement parts like an upgraded extractor, a Ruger OEM laminate stock that I picked up cheap years ago, and upgraded trigger parts. The rifle ran great before the barrel install and ran great after so there was no change in reliability.

The next step was to try to recover some projectiles. This was done fairly easily and it did confirm that the projectiles are swaged slightly smaller and longer than a projectile shot from an OEM 18.5″ Ruger 10/22 barrel.

I gathered a chronograph and two additional 10/22 rifles – one with a Ruger OEM 18.5″ barrel and one with an Ruger OEM 16″ barrel – for velocity testing. Both of the OEM barrels that I used for comparison have very high round counts and that may be playing a role in the data. I used CCI Mini Mags for the testing and saw numbers from the V7 10/22 20 CAL barrel that were more in line with velocities from the Ruger OEM 18.5″ barrel.

The V7 10/22 20 Cal barrel averaged 1227.2 FPS over 50 rounds of CCI Round Nose Mini-Mags. The standard 16″ Ruger OEM barrel averaged 1219.2 fps and the 18.5″ averaged right at 1224 fps. The 16.1″ V7 barrel was producing velocities faster than the longer 18.5″ barrel. Some of that could have to do with the round counts on the barrel in question and some with the properties of the V7 barrel.

Accuracy was excellent with CCI Mini Mags. I generally sight my .22 rifles at 50 yards and that is also where I did my accuracy testing. The groups averaged just over .69″ in max spread at 50 yards with the group pictured below being pretty typical. I suspect a better shooter could print more impressive results as I often had 1 or 2 fliers that had a large effect on overall group size.

Aside from all the performance numbers, I should also point out the less tangible qualities of this barrel. It is light, short, and looks great. So many after-market barrel makers neglect the sporter profiles barrels. Not everyone wants a heavy target rifle. Some of us want to actually spend time with our rifles in hand, walking the woods and that is the domain of the sporter profile barrel.

Wrap Up

These barrels could really stand to be tested beyond my capabilities to truly flesh out their claims – especially regarding down range energy. However, here is what I know… The barrel offers a great accuracy improvement over an OEM barrel. The V7 10/22 20 CAL barrel shows a slight increase in velocity over OEM barrels (even OEM barrels that are longer). Finally, the projectiles actually are swaged to a smaller diameter and increased overall length which should theoretically increase BC and thus down range performance to some extent. All of that points to confirmation of the claims.

I am impressed with the performance and handling of this barrel. I have found it to be a source of endless fascination and conversation with other gun guys… and it shoots.

Gear Dynamics Custom Chest Rig

Custom gear makers provide a valuable resource to shooters. You’ve heard me say things like that before. It is nice knowing that when you have an idea for a gear item that just doesn’t exist, there are craftsman out there who can make it a reality.

This custom chest rig from Gear Dynamics is a great example. The customer is a competition shooter who wanted to be able to mount pouches at an angle, presumably to enhance the speed at which the contents of those pouches could be accessed. Something like this chest rig could probably be pieced together with a regular chest rig and a handful of adapters but it would never be as sleek as this purpose built, custom piece.

Aridus Industries CROM – Rob Haught Mod

Aridus Industries is now offering a modified version of their CROM optic/sight mount for Beretta 1301 and Remington 870 shotguns. The modification is inspired by defensive shotgun guru Rob Haught’s preferred ghost ring set up. The ghost ring is cut in half so that only a “U” remains. Aridus Industries states that this sight up allows for faster sighting and less obstruction of the sight picture through a mounted red dot sight.

The sights are milled to shape, deburred, and then parkerized. They are available as an option on new CROMs or for purchase separately to retrofit your existing CROM.
