Desert Tan Surefeed Magazines Now Available

Friday, May 26th, 2017

New Britain, CT –SureFeed AR-15 magazines by Okay Industries are now available in Desert Tan. Introduced to meet market demand, these magazines are manufactured to the same exacting standards as all Okay Industries magazines which meet or exceed U.S. Military Specifications. Popular with U.S. soldiers, Government Agencies and sought after by civilian shooters alike, OKAY magazines are renowned for reliable feeding and flawless performance in any Mil-Spec AR-15 compatible platform. Since co-developing the original 30 round M16 magazine with the U.S. Military in 1973, OKAY magazines have earned a reputation as the best USGI versions available.

Like all SureFeed® USGI type magazines, the new Desert Tan 20 and 30 round magazines are 100% made in the U.S.A. with components that meet or exceed demanding Mil-Spec requirements. The magazine bodies and floor plates are made from lightweight aluminum that is heat treated and hard coat anodized for strength and durability. A proprietary Desert Tan coating is applied to the magazine body that has a nano-PTFE additive for increased lubricity, as well as a boron additive for durability which exponentially improves performance and reliability.


A four way anti tilt self-lubricating non-hygroscopic resin follower in the 30 round magazines and a high performance Mil-Spec stainless steel spring keep rounds properly aligned and tensioned for flawless performance.
Reliability is the most important quality for any magazine. Okay Industries achieves this reliability through extensive quality controls. Every magazine goes through an exhaustive battery of inspections and tests before being shipped. Some of the areas tested include weld integrity verification, feed lip tolerance and material quality. This all leads up to the final proprietary qualification where each magazine is tested for fit and function. This proprietary inspection and testing process and the resulting superior quality of SureFeed® magazines is why OKAY has been a supplier to the U.S. Government since 1973.

Desert Tan SureFeed® magazine are now available in the 30 round capacity with an MSRP of $18.95-$19.95. For more information visit or the Facebook page at

Marine Corps Issues Sources Sought Notice for Marksmanship Technology Demonstration (MTD) 2017

Thursday, May 18th, 2017

The Marine Corps has issued a Sources Sought Notice to identify technologies for the upcoming Marksmanship Technology Demonstration (MTD) 2017 which will be held at Calvin A. Lloyd Range Complex, Weapons Training Battalion, Marine Corps Base Quantico from 19-21 September 2017 and is aligned with Modern Day Marine. This is a closed demonstration.

Weapons Training Battalion (WTBn), Marine Corps Base Quantico, is the proponent for marksmanship for the United States Marine Corps. As such, this demonstration will identify current and emerging technologies that demonstrate possible solutions to marksmanship gaps and inform Marine Corps future requirements development.

Last year, the Marines looked at Marine load and protection issues. This year, MTD 2017 will focus on five technology areas:
1. Small arms automated smart static targets
2. Small arms automated smart mobile targets
3. Infantry Rifle
4. Infantry Rifle Suppressors
5. Infantry Rifle Optics

SOFIC – Geissele High Speed Selector for M4/M16

Wednesday, May 17th, 2017

The Marine Corps conducted a study which showed that full auto fire is more effective than semi auto fire when engaging moving targets. However, the weapon had to already be set to full auto. Otherwise, the time it took to rotate the selector switch into position would result in a missed target. They asked Geissele Automatics to take a look at the issue and they came up with the High Speed Selector.

You can think of it as a spring loaded selector with a quarter throw. When you depress it, the rifle transitions from semi to full auto and when you let up, it transitions back to semi auto fire. It’s kind of like hitting the nitrous button on a hot rod.

SOFIC – Handl Defense Introduces SR25 Magazine Magwell Adapter For HK417

Wednesday, May 17th, 2017

Handl Defense has been making accessories for the FN SCAR for years and thought they’d try their hand at Heckler & Koch weapons. A common complaint of the HK417 is that it requires proprietary magazines. Not anymore.

Thanks to Handl’s new 417-M110 magwell adapter, the weapon will now accept SR25 pattern magazines like this one from Magpul. The HK417’s magwell is already oversized to accommodate the thick walled H&K magazine, so there’s plenty of room for the patented insert. It also uses a new magazine release.

Spuhr – M203 Mount For AK5C

Tuesday, May 16th, 2017

Swedish Air Force Rangers using AK5C with M203 attached via Spuhr’s forend that is permanently attached to M203 along with the Spuhr M203 sight with Aimpoint.

This solution provides 24 hour capability on the 40mm as well as increased accuracy.

Magnetospeed M-Series Grip

Wednesday, May 10th, 2017

Magnetospeed debuted their M-Series pistol grip at SHOT Show.

It’s a very interesting take on an ergonomic, stowable pistol grip for the AR family of weapons. Their internal, module ejection system allows users to store a number of different and useful modules within the grip itself so that they are always ready to deploy at a moment’s notice. Constructed from high performance, glass-reinforced Nylon, the rigid grip has unique texturing to enhance control and comfort. An overall matte texture is accompanied by coarser friction pads along the sides as well as a polished region under the backstrap to reduce wear on thumb webbing.

Details On The USSOCOM Sponsored KeyMod vs M-LOK Test Conducted at NSWC-Crane

Friday, May 5th, 2017

During this week’s NDIA Armaments Conference, Caleb McGee from Naval Surface Warfare Center – Crane conducted a briefing which detailed the test protocols used to evaluate the KeyMod and M-LOK weapon accessory attachment systems on behalf of the United States Special Operations Command. We recently published a FOIA released summary of that test which indicates that SOCOM selected M-LOK for use on the Suppressed Upper Reciever Group and Advanced Sniper Rifle programs. This briefing explains why they made that decision.

Crane procured Commercial-Off-The-Shelf rail systems which were offered in both KeyMod and M-LOK variants so as to offer direct comparisons. Modular rail systems were evaluated for repeatability, endurance, rough handling, drop testing, and static failure load.


The most remarkable differences between the two types of attachments was observed during repeatability testing. With variations measured in MOA, KeyMod exhibited a spread from 0.2 to 14.6 while M-LOK varied from 0.0 To 6.6 POA shift.


For the Endurance and Rough Handling tests, both KeyMod and M-LOK passed testing.



The imagery from the impact tests are shocking until you consider how the rails were tested.


Regardless, the results are clear.




In failure load testing which attempts to pull accessories from the rail from 90 Deg off-axis, Crane noted an increase of 215% in average sustained load of M-LOK over KeyMod.


Granted, the sample size of this testing is limited. However, for SOCOM, the conclusions were clear enough to choose a path forward. This test concludes that M-LOK is a more robust and more stable system. In addition to repeatedly maintaining point of aim for mounted accessories during normal mounting and remounting, it also better maintained rail intagrity in spite of impacts. On the other hand, testing shows that KeyMod suffered significant POA shifts during both repeated mounting and remounting as well as after impacts. Additionally, while both systems noted cracking under impact, some KeyMod rail samples lost integrity with fracturing beteeen slots.


One additional point to consider; Crane noted that it was extremely important to properly mount accessories to the rail. KeyMod did a much better job of self-aligning the accessory during mounting while M-LOK required more attention. The takeaway here is to pay attention while attaching accessories to the rail and to check zero after mounting.


For those interested, we have provided the entire briefing here. However, it will also be available on the NDIA proceedings section of the DTIC website in the next few weeks.
