Tactical Handyman: No Slot? No Problem!

Don't let the lack of a pre-made slot keep you from mounting your Mount-N-Slot where you need it.

When it comes to attaching Impact Weapon Component’s Mount-N-Slot hardware, don’t limit yourself to only the places that you have a pre-made slot. The flat sides of the Magpul MOE Hand Guards make attaching a Mount-N-Slot in a custom location an easy task.

In this installment of the Tactical Handyman, we will mount a Mount-N-Slot Rotation Limited QD Sling on midlength Magpul MOE Hand Guards. The midlength MOE Hand Guards lack slots on the sides close to the receiver which is a shame because this is an optimal place to mount a sling swivel.

The midlength MOE Hand Guards lack slots on the rear sides. This is where we will attach the Mount-N-Slot.

Materials:

  • Mount-N-Slot of your choice
  • Magpul MOE Hand Guards
  • Drill with 7/32″ bit
  • Ruler (with long straight edge)
  • Pencil
  • Awl (optional but can be useful for cleaning up or slightly enlarging the drill holes, a Swiss Army Knife works great)

Measure carefully and mark your two drill locations as outlined in steps 3 through 5 below.

Procedure:

  1. Check that your Ar-15 is unloaded by removing the magazine and then visually inspecting the chamber. Once you have completed this, check it again. Remove all ammunition from your work space.
  2. Remove the MOE Hand Guards from your AR-15.
  3. Use your ruler and pencil to draw a line that runs through the center of the slots, parallel to the bore. NOTE: The results of steps 3-5 are shown in the picture above.
  4. Mark the drill hole closest to the delta ring on the line taking care to place it in such a way that the Mount-N-Slot can lay flat when mounted.
  5. Mark your second drill hole by measuring 11/16″ from your first hole. The two mounting points on a Mount-N-Slot Rotation Limited QD Sling are about 11/16″ center to center. You will have to measure any other Mount-N-Slot you may be using.
  6. Drill both holes using a 7/32″ drill bit.
  7. Clean up the holes as necessary with an awl or small sharp knife.
  8. Attach the Mount-N-Slot per manufacturer instructions using the two newly drilled holes instead of a slot.

This is a simple project with a big pay off in increased functionality. Mounting the sling in this location improves the range of motion you will have with the AR slung and keeps the hand guard well clear so you have plenty of room to hold it with your support hand.

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.

Click to enlarge.

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. This rail is a much needed upgrade for the excellent SCAR series of rifles.

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.
