M-LOK

Magpul just released a new rail accessory mounting system that’s compatible with slotted, a.k.a. ‘negative space’ handguard mounting points. Magpul calls the system M-Lok and says the company is releasing it as a cost-free, licensed platform to promote compatibility with accessories across the market. The system will be another market standard, Magpul hopes, that will compete with KeyMod and Picatinny rail attachment systems.

The great strength of the system seems to be the ability to mount accessories or accessory rail sections to slotted openings without having to fish backers into the void between your rifle barrel and handguard. M-Lok features a semi-captured backer that allows you to slip the part into position and screw it in place on rails with compatible spacing.

As far as buy in from established manufacturers, it looks like Geissele Automatics has jumped on board and announced their upcoming Mk8 handguard will use M-Lok.

Magpul says M-Lok is compatible with the slots found in their current line of MOE handguards with an adapter. Moving forward, they will be transitioning all MOE products to the M-Lok standard over the next year-and-a-half. MOE accessories for use with original MOE slotted handguards will still be available for 18 months before they are phased out.

M-LOK stands for Modular Lock system. The M-LOK system retains an elongated slot appearance, similar to Magpul’s  MOE slots (with different dimensions). The new slot is larger, has squared sides, and the new system adds the following feature set:

  • Direct mount capability
  • Cammed T-nut
  • Optimized for metal and polymer manufacturing
  • Recoil/impact mitigation lugs
  • Intermediate spacing option
  • Multi-directional mounting
  • Backwards MOE compatibility

More information on the system and Magpul’s roadmap for the system going forward are available in this PDF.

The Sig Sauer MCX was born as rifle caliber replacement for the Heckler & Koch MP5SD submachine gun. Why? Well, because they could. Submachine guns developed prior to the MCX were hamstrung by technology and materials that limited their reliable operation to pistol cartridge pressure levels. But, rifle power performance in a compact form factor is what we’ve come to expect as desktop computers are replaced by phones the size of a candy bar.

Ditching the handgun cartridge and running more powerful rifle ammunition called for an updated operating system. The MP5′s roller lock, delayed blowback system is fine for pistol caliber loads, but these systems struggle to deal with the higher pressures of rifle caliber loads. While the MP5 is arguably one of the most reliable guns on the planet, you can look at the HK G3 for a hint of how the higher chamber pressure of a rifle round affect roller lock, delayed blowback systems. In a blowback system, the brass case is still filled with chamber gasses at the beginning stage of extraction. HK had to use a fluted chamber in the G3 so the brass has room to expand and contract in order to provide reliable extraction. (Even so, torn cases are not unheard of in the G3.)

In a Stoner system, the gasses are vented through the gas port and the chamber pressure is much lower by the time extraction happens. So Sig Sauer decided that the rotating, locking bolt, as we’ve become used to on the Stoner AR action, is needed to provide reliable extraction and safely contain the chamber pressures of rifle cartridges.

Paying $200 for a Form 1 or Form 4 tax stamp feels like paying uncle same for a punch in the face. AAC gets it, and while they can’t take the hit for you, they can help absorb the pain with a $200 credit to use on their webstore with the purchase of one of their silencers or short barreled rifles.

That’s not a bad way to pick up another muzzle device so you can put your new can on another gun. If you’re going the Element2 route, that $60 Element baffle removal tool comes in handy if you get lazy on the maintenance schedule and let it lead up. Or, maybe you just want to have a bunch of AAC stickers, patches and t-shirts on hand (they make great party favors for your friends that like guns or skulls, or both.)

The fine print says the credit is only good on items AAC has in stock, so if you’re going for it and you have your eye on a certain part that might be popular, get moving. The whole shebang is good now through July 5, 2014, but check out AAC’s promotion page for a rundown of the details.

Notification2

Remington Arms Company is recalling Model 700 and Model 7 rifles with X-Mark Pro triggers that were manufactured between May 1, 2006 and April 9, 2014. Rifle owners are advised to immediately stop using their rifles and determine whether they are subject to this recall.

Military Times GearScout is waiting on a comment from Remington on this subject. Update:According to Ted Novin, spokesman for Remington Outdoor Co., the X-Mark trigger isn’t used in any Remington Military products. He say’s there aren’t any defense rifles involved in the recall.

With about 5.3 million Model 700′s alone out in the wild since its debut in 1962, we can estimate Big Green sold an average of 100,000 rifles per year. With an 8 year recall window, rough (very rough) math tells us there could be more than 800,000 Model 700 rifles alone subject to this recall. That seems like a lot, but when you factor in the Model 7 and the surge of rifles sales in the last couple of years, that number is likely between 1.2 to 1.3 million rifles.

The trouble, according to Remington’s product notification, is that excess bonding agent used in the assembly of the X-Mark Pro trigger in some rifles can lead to unintentional discharge of the rifles. Remington says the only remedy is to send recalled rifles in for inspection, cleaning and testing. They stress that consumers shouldn’t try to clean the triggers themselves.

Remington says the recall will be performed at no cost to the customer.

The two ways to determine if you have a recalled Model 700 or Model 7 are as follows:

serial

1. Identify the serial number and provide it to Remington’s recall support team, either by entering it at xmprecall.remington.com or calling 1-800-243-9700 (Prompt #3 then Prompt #1) Monday through Friday, 9 a.m. to 5 p.m. EDT. You will be informed if your rifle is affected by this recall and given the resources needed to return the rifle for inspection and specialized cleaning.

Notification2

2. Look at the trigger. If the face of the trigger is ribbed (Photo 1 above), your rifle does not have an XMP trigger and is NOT subject to this recall. If the face of the trigger is smooth (Photo 2 above), your rifle has an XMP trigger and IS subject to this recall in which case you should immediately seek further assistance at by calling 1-800-243-9700 (Prompt #3 then Prompt #1) Monday through Friday, 9 a.m. to 5 p.m. EDT or by visiting xmprecall.remington.com.

punchedRemington says as of April 9th, 2014 they’ve begun performing corrective action on rifles that have yet to be shipped. You can tell if you’re looking at a properly built trigger and rifle by the presence of a punch mark (above) on the bolt release. Rifles that are returned to customers will also have the punch mark that confirms the rifle has been inspected and cleaned.

So, going forward from today, you don’t want to mess with any Model 700s or Model 7s that have a smooth-faced trigger bow and no punch mark on the bolt release.

I’ve asked Remington what they suggest to customers that have moved a recalled action/trigger to a different, aftermarket stock or have replaced a recalled X-Mark Pro with an aftermarket trigger. They haven’t commented, yet, but I’m willing to bet they won’t work on triggers that are outside the receiver because of the liability involved should an improperly, customer installed trigger be involved in an accident. Though, I hope they will. If they refuse to swap take-off triggers from recalled guns then there is a good chance that someone will someday put a bad trigger back in a later rifle build inadvertently (or advertently.)

Actions moved to other stocks seem like they wouldn’t be that hard to work with, but if the recall is as big as it could be, then they aren’t going to have the time to figure out how to work on every aftermarket Model 700/Model 7 stock out there. They’ll likely say the barreled action be removed from an aftermarket stock, or the rifle must be returned to its factory configuration before it’s sent in.

We’ll update this article when we hear back from Remington on the subject. In the meantime, Remington is offering recalled rifle owners a 40% discount good for items on ShopRemingtonCountry.com and/or Remington1816.com. The details are visible after consumers complete the recall form.

Many, if not most fights, happen in low-light. But for EDC — particularly concealed carry — having a dedicated weapon light with a special holster isn’t a reasonable option.

Plus, for those of us on a budget, having your EDC light double as your weapon light is appealing. I’ve used Safariland’s Rapid Light System in the past and I’m a big fan. It is easy to use, it can be attached and detached quickly eliminating the need for a special holster and it  allows you to maintain a two-handed grip. But, it is conspicuous. Not to mention it is more bulk than I want on my belt or in my pocket when I’m running

brace

We received a copy of a letter from the ATF’s Firearms Technology Branch concerning the use of arm braces on AR pistols that referenced the Sig Sauer SB15 pistol stabilizing brace specifically.

The ATF’s letter says that they’ve determined that firing a pistol from the shoulder would not cause the pistol to be reclassified as an SBR.

The letter, signed by the Chief of the ATF’s Firearms Technology Branch, Earl Griffith,  states, “the firing of a weapon from a particular position, such as placing the receiver extension of an AR-15 type pistol on the user’s shoulder, does not change the classification of a weapon.”

“Further,” wrote Griffith, “certain firearm accessories such as the SIG Stability Brace have not been classified by FTB as shoulder stocks and, therefore, using the brace improperly does not constitute a design change.”

This clears up any doubts that firing an AR pistol using the distinctly buttstock-looking SB15 could get you in trouble, even if fired while shouldered.

The Knights Armament SOF Light Individual Carbine Kalashnikov (SLICK) was one of KAC’s entries for the Special Operations Command combat assault rifle program (SCAR). It didn’t win, but there is some very interesting engineering going on in the rifle and KAC shared some details of the stillborn rifle in this a video shared on their KnightsArmCo YouTube channel that also looks at their more conventional entry SR15-based entry and the FN SCAR that SOF ultimately adopted.
