Rainier Arms Select 5.56MM Barrel

We all know precision barrels for the AR-15 don’t come cheap and you generally get what you pay for. The Rainier Arms Select 5.56MM Barrel turns that convention on its ear. It offers features and performance that can usually only be found on barrels that cost twice as much.

These barrels feature polygonal rifling which is a functional feature that is usually reserved for more expensive barrels. Polygonal rifling forms a tighter seal around the projectile which leads to higher velocities, and, because it lacks the grooves of typical cut rifling, it tends to suffer from less copper and lead build up. Barrels with polygonal rifling also tend to last longer than their cut rifling counterparts.

Other features include:

  • Bead blasted stainless or black oxide finishes
  • 416R stainless steel construction
  • 1×8 Twist
  • M4 feed ramps
  • 5.56 chamber
  • Midlength gas system
  • The Rainier Arms Select 5.56MM Barrel
  • 16″ length

The Rainier Arms Select 5.56 Barrel offers some pretty staggering features for a barrel that sells for just $189.95! Check out these barrels at the Rainier Arms webstore or visit the Rainier Arms Industry Forum on AR15.com.

LaRue Tactical R.I.S.R.

The LaRue Tactical R.I.S.R. is a new and interesting approach to an old problem. The charging handle of the AR family of rifles runs along the top of the stock when it is extended. If a user of one of these rifles wants to install some kind of comb riser to their rifle they needed to install it close to butt of a fixed stock or run an adjustable in the last position. If it is installed too close to the receiver it will interfere with the function of the charging handle which is obviously unacceptable.

The R.I.S.R. is designed to slide with the charging handle. It bolts onto the Magpul CTR or MOE stock and allows the stock to be put in a variety of positions without interfering with the charging handle. The folks at LaRue claim that the R.I.S.R. was built with the worst case scenario in mind and they have tested it with sand, dust, dirt, and more without being able to make it seize.

A product like this is especially needed on the LaRue Tactical OBR. The OBR has elevation built into the receiver rail which can cause optics to sit quite high. Until now, OBR users were stuck with comb risers on fixed stocks or on collapsible stock in the fully open position. The R.I.S.R. should give them some much needed options.

The R.I.S.R. will be available from LaRue Tactical around the end of 2010. You can read more at the LaRue Tactical Industry Forum on AR15.com.

Tango Down Translucent ARC Magazines

Translucent AR-15 magazines are a great idea. It makes good sense to be able to estimate how many rounds you have left at a glance. However, translucent plastics have always offered a challenge for product designers because they tend to be more brittle than their opaque counterparts. This brittleness often leads to cracked feed lips. Many clear magazines have used metal reinforced feed lips with varying degrees of success.

The Tango Down ARC magazine’s unique two piece design allows a different take on the clear magazine. The feed lips and entire upper part of the magazine is made from black plastic. Black plastic is generally stronger than plastic dyed other colors so this design is actually an advantage for the ARC mags of all colors. The opaque black part of the magazine is completely covered by the receiver when the magazine is inserted so there is no disadvantage to making it opaque.

If you are in the market for translucent (or any color) magazines for your AR-15, consider the Tango Down ARC magazines.

Low Speed, High Drag T-Shirt from 2A-GEAR

I am glad that there are people in this world that are much more high speed than me. Thank you to all you high speed guys who stand between this country and hordes of evil doers. I appreciate the hard work and sacrifice of all you high speed, low drag guys.

We can’t all be high speed. I do what I can to be ready to protect my family, but I am far from high speed, low drag. You could probably say that I am low speed, high drag (hence the tag line of this blog). It may be that some of you are low speed, high drag, too. If that is the case, 2A-Gear has the shirt for you (and me).

You can check out this shirt and other great items at 2A-GEAR.com.

End Cap for the Battle Arms Development – Ambidextrous Safety Selector

Click to enlarge.

The previously reviewed Battle Arms Development – Ambidextrous Safety Selector (BAD-ASS) is already the most versatile selector on the market. Now, with the addition of the new end cap, that versatility is expanded. I mentioned the end cap previously on Jerking the Trigger and now that I have one in hand, there are no surprises. It works.

Installation is a breeze. You simply bolt the end cap on to the BAD-ASS core. Be careful to align it so that the indicator notch is pointing to the correct selector position (safe or fire).

Once the end cap is installed correctly, it stays completely out of the way of the trigger finger and provides visual indication of the condition of your weapon (safe or fire). This cap makes the BAD-ASS relevant to those who may not have a need for an ambi selector but do want the quality, durability, and ergonomic enhancement of the finest selector available for the AR family of weapons. If you want a left side only lever, you can do that. If you want a right side only lever, you can do that, too. There is no shortage of options with the BAD-ASS.

You can purchase your own at the Battle Arms Development website. It is available for purchase separately or as part of a complete BAD-ASS kit.

Branham Tactical SCAR 2″ Extension Rail

AIM Surplus recently introduced the long awaited extension rail from Branham Tactical. It adds 2″ inches of rail space to the two side rails and the bottom rail. This extension rail will give users more light mounting options and help out those user who like to run their support hand closer to the muzzle.

New End Cap for the BAD-ASS

Click to enlarge.

If you have been reading Jerking the Trigger recently you are already familiar with the Battle Arms Development – Ambidextrous Safety Selector (or BAD-ASS). I say the BAD-ASS is the finest AR safety selector that I have ever used due to the versatility bred by its user configurable levers, its ergonomic enhancements, and its impeccable quality.

Well, Battle Arms Development just made the most versatile selector switch ever developed for the AR family of weapons even more versatile with the introduction of the new end cap. This end cap can be used to make either side of the BAD-ASS lever free. Now, with this end cap you can easily convert the BAD-ASS from ambidextrous to left or right side only.

The end cap has a notch that serves as a condition indicator (safe or fire). It is available separately for purchase or as part of a complete BAD-ASS kit.

If ambidextrous selectors just aren’t your thing, but you still want the performance and precision that the BAD-ASS offers, the new end cap is for you.

10-8 Performance Sights

When you think 10-8 Performance, you think 1911. While Hilton Yam, owner of 10-8 Performance, does make excellent 1911 accessories and custom 1911s, he also makes excellent sights for a variety of other handguns. The sights that we will be looking at in this article are made for the Glock family of handguns.

 

The 10-8 Performance Sights offer a very uncluttered sight picture even with a tritium vial insert in the front sight (mounted on a Glock 19 for reference). Click to enlarge.

 

Stats

  • Front sight width: .125″
  • Rear sight notch: .140″ (.125″ and .156″ also available)
  • Price: $74 for tritium front sight, $44.35 for rear sight

Front Sight

The 10-8 Performance front sight is thin for a tritium front sight at only .125″ inches wide. It is serrated to reduce glare and the tritium element is unlined. The unlined tritium is what attracted me to these sights. They perform very much like all black target sights when light conditions allow and that makes them very shootable.

 

The 10-8 Performance front sight is relatively thin and serrated. It features an unlined tritium vial insert. Click to enlarge.

 

10-8 Performance also offers plain black and brass bead front sights.

Rear Sight

The rear sight is well contoured. It has an strong, chunky appearance. It can be used fairly easily to rack the slide which is important for some one handed manipulations. It is serrated to reduce glare.

 

 

The rear sight features glare reducing serrations and a .140" rear "U" notch. Click to enlarge.

 

It features a true “U” notch. The bottom of the notch is round instead of square. This leaves the shooter free of hard corners that can distract from aligning the only hard corners that matter; the ones at the top of the front sight and the top of the rear sight.

When I purchased these sights, the only rear sight notch options were available were the .125″ and the .140″. I chose the .140″ rear sight and always wished it was a bit wider. The .140″ notch feels a little tight when you are trying to speed things up. 10-8 Performance recently started offering a rear sight with a .156″ notch. If I was buying these sights today, I would definitely buy the new .156″ notch rear sight.

 

The rear sight has a strong, chunky profile. Click to enlarge.

 

In Use

I shoot these sights better than any other I own in terms of accuracy. The combination of the tighter rear notch and the way that they appear like all black target sights during the day (the tritium vial insert is unlined and barely noticeable until dark). These sights are just very easy to shoot well. The downside is that sometimes I feel like I am searching for the front sight through the narrow rear notch which costs me some time.

That is not to say these sights are slow. They are not. They just are not as fast as some others that I use and 10-8 Performance has essentially rendered this small issue (if you can even call it that) irrelevant with the introduction of the .156″ notch rear sight. I suspect that the new wider rear sight shoots incredibly fast. The intro of the 1.56″ rear notch should be exciting news for the many fans of these sights.

The 10-8 Sights with the .215″ tall front sight shoot exactly the way I like which is about 1-2″ high at 25 yards. This is relatively intuitive after some range time and allows the shooter to see their shots over the sights. I find it to be easier to shoot longer distances this way. If you choose to, you can adjust your point of impact by purchasing a taller or shorter front sight. You can read details on the 10-8 Performance blog.

You can purchase these excellent sights directly from 10-8 Performance on their website.

BattleComp 1.5

I have mentioned the BattleComp on Jerking the Trigger before. It is a compensator for the AR family of weapons that may be nothing short of revolutionary. Much like many other advanced compensators on the market, this one tames muzzle rise and suppresses flash nearly as effectively as an A2 flash suppressor.

However, unlike other advanced compensators on the market, the BattleComp does not redirect any additional sound or blast to the back or sides. This means that it is effective in situations where other compensators would have been a detriment – like indoors, working as a team, or in improvised shooting positions. This is a compensator with seemingly no downside. This is an evolutionary step forward.

14.5″ barrels continue to gain popularity because of their handiness and lighter weight. They can also be used on non-NFA weapons simply by permanently attaching a muzzle device that brings the total length to 16″ (14.5″ barrel + 1.5″ muzzle device = 16″). The best way to attach this muzzle device is by pinning. This ensures the the device will be permanently attached and will meet the 16″ barrel length requirement.

Now the designers of the BattleComp have created a new version, the BattleComp 1.5, with users of 14.5″ barrels in mind. It is purpose built to be long enough to bring a 14.5″ barrel to the required 16″ length and it is pre-drilled for pinning. It is available in black oxide and matte stainless finishes and retails for $155.

The BattleComp 1.5 looks like just the thing to help tame the sharp recoil pulse of a 14.5″ carbine gas barrel or to make your 14.5″ mid-length gas barrel even more smooth.

You can read more and purchase a BattleComp 1.5 at the BattleComp website.
