Barrel-Making: How Ruger Crafts Hammer-Forged Barrels

Ruger Firearms Barrel Making Hammer Forging
This image shows a barrel in the process of hammer forging. Watch this operation starting at 1:15 in the video linked below.

You have probably heard the term “hammer-forged barrel”. But do you know how the cold hammer-forging process works? In this interesting video from Ruger, you can see the full barrel making process, including cold hammer-forging on a massive machine. Watch long rods of steel barrel material get cut to length, then drilled. After that Ruger uses CNC machines to contour the barrels before hammer forging.

Anyone with an interest in barrel-making should watch this video:

As the barrel is cold hammer-forged, a giant machine literally pounds the barrel from all sides around an internal carbide mandrel, which forms the rifling inside the bore. The actual hammer-forging is illustrated starting at 1:15 in this video. Through the process of cold-working the barrel around the mandrel, the barrel ends up with a longer length, a smaller outside diameter, and a higher hardness.

Before hammer forging, the barrels are deep-hole drilled, four at a time, with a bit that is slightly larger diameter than the caliber planned for the barrel.

Following the drilling, the barrel rod is placed in CNC machines to be turned down to the correct outside shape and size and both ends are trimmed.

Maryland Gun Law Ruling — ‘Strict Scrutiny’ Should Apply

Court of Appeals Maryland 4th Second Amendment

Appeals Court Remands Decision for ‘Strict Scrutiny’ of Second Amendment Issue.
Earlier this week, the U.S. Court of Appeals for the Fourth Circuit overturned a Federal District Court decision finding the 2013 State of Maryland Firearm Safety Act (FSA) to be constitutional under “intermediate scrutiny” review. In the Case of Kolbe v. Maryland, the Appellate Court held that Maryland’s FSA should, as a matter of law, be subject to “strict scrutiny” under the Second Amendment of the U.S. Constitution. The Kolbe v. Maryland case was filed to challenge Maryland’s 2013 ban on so-called assault weapons and high-capacity magazines.

The National Shooting Sports Foundation (NSSF), which helped challenge the Maryland law, explained that this bodes well for those seeking to nullify portions of Maryland’s 2013 FSA which imposed broad restrictions on firearms including semi-automatic rifles. The NSSF reports:

The [Appellate Court] vacated the District Court’s denial of the plaintiffs’ claims and remanded the case to the lower court, ordering that it apply the appropriate strict standard of review.

Writing for the three-judge appellate court panel that heard the case, Kolbe v. Maryland, Chief Judge William B. Traxler wrote: “In our view, Maryland law implicates the core protection of the Second Amendment — ‘the right of law-abiding responsible citizens to use arms in defense of hearth and home, District of Columbia v. Heller, 554 U.S. 570,635 (2008), and we are compelled by Heller and McDonald v. City of Chicago, 561 U.S. 742 (2010), as well as our own precedent in the wake of these decisions to conclude that the burden is substantial and strict scrutiny is the applicable standard or review for Plaintiffs’ Second Amendment claim.”

“We are greatly heartened by the Fourth Circuit panel’s ruling today,” said Lawrence G. Keane, NSSF Senior Vice President and General Counsel. “As this important case goes forward, NSSF will continue to work with our co-plaintiffs to ensure that our citizens’ Second Amendment rights are protected and that the lawful commerce in firearms is restored in support of this constitutional protection.”

Response from NRA Institute for Legislative Action
Chris W. Cox, the executive director of the National Rifle Association’s Institute for Legislative Action, issued the following statement in reaction to the 4th Circuit Court of Appeals decision in Kolbe v. Maryland: “The Fourth Circuit’s ruling is an important victory for the Second Amendment. Maryland’s ban on commonly owned firearms and magazines clearly violates our fundamental, individual right to keep and bear arms for self-defense. The highest level of judicial scrutiny should apply when governments try to restrict our Second Amendment freedoms.”

Dry-Firing Protective Devices for AR Shooters

Dry-firing practice can benefit all competitors, particularly sling-shooters. However, for AR15 Service Rifle shooters and High Power competitors using AR-based “spaceguns”, dry-firing is complicated by the charging handle location — pulling back on the handle requires that you move your head placement on the rifle. In addition, extensive AR dry-firing can cause pre-mature wear of an AR’s firing pin. AR shooters take heart — now there are products that allow you to dry-fire your AR more easily, without breaking position, and with no adverse effects on the firing pin.

Creedmoor AR15/M16 Dry-Firing Device
Creedmoor Sports offers a Delrin dry-firing device that allows you to reset your AR trigger with a very short pull of the charging handle — plus you don’t have to break position. Machined from solid Delrin, the dry-fire device is inserted into the bolt carrier and limits the swing of the hammer, allowing unlimited dry-firing without the risk of firing pin damage. The trigger pull is unchanged and the shooter can reset the trigger mechanism by cycling the charging handle a mere one-quarter inch or so. The shooter can reset his trigger without breaking position and the lessened impact of the hammer allows the shooter to better evaluate his sight picture and follow-through. Creedmoor’s AR-15/M16 Service Rifle Dry-Fire Device, item #C1051, retails for $18.95

Other AR Dry-Firing Devices
MidwayUSA offers a similar Delrin dry-firing device for ARs. Like the Creedmoor unit, this TMA-made device fits in the bolt carrier group and protects the firing pin from damage. The orange unit slips between the buffer and bolt, and permits the trigger reset with only a quarter-inch movement of the charging handle. During storage the device can also provide a safety function by preventing the hammer from hitting the firing pin. But, we caution, don’t leave your gun loaded presuming this device, by itself, will make the gun safe. MidwayUSA’s orange Delrin AR dry-firing device, item #872223, costs $17.29.
