Great Gun Stuff Blog

I hope y'all have a fantastic Thanksgiving.

Michael Bane said it much more eloquently than I ever could, but like Michael I am thankful for each of you who read the blog. If you were not reading it, I would not be running it.

Regular blog posting will resume on Monday. Have a great weekend.

Michael Bane reports that Spike's Tactical will soon be selling machined billet AR-15 upper receivers.

A leaked US Army report about the Battle of Wanat criticizes the reliability of the M4. On July 13, 2008 200 Taliban fighters attacked 48 US and 24 Afghan troops. Outnumbered 2.7 to 1 the M4 Carbines, which the troops were carrying, could not function reliably under the sustained fire they were required to put downrange. Fox News reports:

The platoon-sized unit of U.S. soldiers and about two dozen Afghan troops was shooting back with such intensity the barrels on their weapons turned white hot. The high rate of fire appears to have put a number of weapons out of commission, even though the guns are tested and built to operate in extreme conditions.

...

"My weapon was overheating,” McKaig said, according to Cubbison’s report. "I had shot about 12 magazines by this point already and it had only been about a half hour or so into the fight. I couldn’t charge my weapon and put another round in because it was too hot, so I got mad and threw my weapon down."

Snowflakes In Hell, via Michael Bane's blog, correctly points out that assault rifles are not machine guns:

No assault rifle is going to stand up to sustained automatic fire. They aren’t machine guns, and even a machine gun needs to have its barrel changed out if it’s been firing a lot.

The M4 has a very short 14.5" barrel and a relatively lightweight barrel profile. This allows the barrel to heat up much faster than a longer and heavier rifle or machine gun barrel. When the barrel of a closed-bolt gun gets very hot, cook-offs,when a round is ignited from the heat in the chamber, become a significant problem ... not to mention the fact that a soldier cannot fire a gun that is to hot to hold!

The Marines have been criticized by many for their plans to introduce an Infantry Automatic Rifle (IAR) into the mix of weapons issued to their troops. The IAR is not intended to replace the SAW but would be deployed alongside it, giving some riflemen a light weight weapon that can sustain automatic fire.

The Army would do well to look into the concept.

At the end of last year the Marines announced they were awarding contracts for the development of IAR prototypes to Colt, H&K and FN. Since then I have heard nothing about the IAR.

There are discussions about the M4 failure at Wanat over at Snowflakes In Hell, via Michael Bane's blog and SaysUncle.

Many thanks to Jerry, Caedis, Lee and Lance for emailing me links about this story.

Michael Bane has written an interesting blog post on the shift in the perception of what a rifle is or should be.

If you read gun blogs and forums as well as owning a few of your own tacti-cool guns, it is easy to think everyone values the black rifle. I agree with Michael that only recently are we seeing the black rifle go mainstream.

However, in truth, nearly every type of rifle was originally designed for the battlefield.

After having recently launched their first AR-15, the Ruger SR-556, Ruger have now unveiled the Ruger SR-22, a Ruger 10/22 in a tactical AR-15 configuration. For years we have been asking for it, and finally they have delivered!

You are probably thinking that the action in the above rifle does not look much like a Ruger 10/22. This is because a standard Ruger 10/22 action and trigger group sits inside a Nordic Components designed conversion chassis / enclosure.

The chassis allows a standard AR-15 stock and pistol grip to be used on the rifle. It also allows a standard Ruger 10/22 barrel, which attaches to a v-Block, to be used with a the AR-15 style handguard. This breakdown photo illustrates how it all fits together:

The mid length handguard is drilled and tapped to allow picatinny rails to be installed on the 3,6,9 and 12 o' clock positions, if desired. These rails allow all standard AR-15 accessories to be used with the rifle.

Another benefit of the SR-22 over a standard 10/22 is that the barrel is factory threaded and a Ruger SR-556 / Mini-14 flash suppressor is installed.

The Ruger press release:

Sturm, Ruger & Company, Inc. (NYSE-RGR) announces the introduction of the Ruger® SR-22™ Rifle, an autoloading, rimfire rifle that combines the legendary reliability of the Ruger® 10/22® with the ergonomics and configurability of the new AR-style Ruger SR-556™. The new SR-22 Rifle allows shooters to use economical .22 LR ammunition, while still enjoying the look and feel of an "AR" and experiencing the reliability they have come to appreciate from Ruger.

Because it utilizes the unique rotary magazine supplied with the Ruger 10/22, the SR-22 Rifle offers the same gold standard for reliability in autoloading rimfire rifles. Like the 10/22, the AR-style SR-22 Rifle also has an extensive array of accessories available, allowing shooters to select a custom configuration that best suits their tastes and needs.

The SR-22 Rifle uses a standard 10/22 action inside a top-quality, all-aluminum chassis that faithfully replicates the AR-platform dimensions between the sighting plane, buttstock height, and grip. The SR-22 Rifle provides a Picatinny rail optic mount, and includes a six-position, telescoping M4-style buttstock (on a Mil-Spec diameter tube), plus a Hogue® Monogrip® pistol grip. Buttstocks and grips may be swapped out for any AR-style compatible option.

The SR-22 Rifle also features a round, mid-length handguard mounted on a standard-thread AR-style barrel nut. Picatinny rails, specifically designed for this handguard, are available from Ruger, allowing the handguard to be configured to accept any number of rail-mounted sights or accessories. A barrel support block is installed in the handguard, ensuring accuracy and allowing the standard 10/22 V-block barrel attachment system to be used.

The SR-22 Rifle is equipped with a precision-rifled, cold hammer-forged alloy steel barrel. The 16-1/8" barrel is capped with an SR-556/Mini-14 flash suppressor mounted with a 1/2"-28 thread.

Michael Bane has also created a video review over at the Down Range TV Blog. Michael hinted at the rifle earlier this week, but I must admit I did not imagine a tactical Ruger 10/22 was what Ruger had in store for us!
