Glance at the photo above. See anything that may be wrong?
It appears this is a pistol. Notice the muzzle and what I think is the recoil spring guide to the left in the frame. If I am right, the photo depicts a non-recommended way to clean almost every barrel.
The preferred and appropriate way to clean your gun’s chamber and bore is to “push” your cleaning patch, brush, or jag from the chamber and “push” towards the muzzle, just like a bullet travels. In pistols, this normally means removing the barrel from the frame and start your patch, brush, or jag from the chamber. With rifles, the same rule applies. You may need to remove the bolt to be able to push a rod straight through the bore. “Pushing” helps reduce the risk of nicking your barrel crown.
In addition, you can insert the rod starting at the muzzle, pass it through the bore and chamber, attach your brush or patch, and “pull” it back through the bore. The patch or brush still will be traveling as the bullet travels. Of course, multiple passes will require you remove and then re-attach patch or brush each time.
An exception are revolvers, of course. In most cases, you must start from the muzzle since access to the other end of the barrel is not possible with a standard cleaning. Something like a bore snake or a bush that is on a flexible rod (such as is shipped with many new pistols) may give you the option to clean from the back towards the muzzle.
Seems the topic among many of my customers is that of introducing people to the sport of target shooting. A subject that always comes up is the type of pistol to take the first time. Small gun, small caliber; big gun, small caliber; small gun, big caliber, … you get the idea.
We talk about things that worked and things that did not. In almost every conversation, through successes and some epic fails (“I’ll never go shooting again”), several common new shooter fears and success factors for that first time on the range have emerged.
Most first-time shooters are concerned about the noise and the recoil. This is generally followed by the concern not to embarrass themselves or the desire to do well. So, here’s what I and many of my customers have found that works…
Buy good ear protection. Inserts, “ear muffs,” or both. The won’t go to waste. Hey, you could always use them!
Outdoor ranges are ideal. Lots of room so as not to feel cramped. Indoor is OK, too. Just make sure they know the range rules to avoid the ugly looks of fellow shooters and potential finger wagging of a range officer.
Bring a bigger gun, not a smaller one. Think a full-size 1911 versus a pocket pistol. The heavier gun reduces the feel of recoil, probably has better sights, and is big enough that it will take a good, two-handed grip to control. Big guns enable a great opportunity to teach lots of things (sighting, grip, safety) that may be tougher with a smaller gun.
The bigger gun does seem to offer overall better control. Better control means better groups and a feeling of success,
That sums up the experience we’ve all had at one time or another. Good luck you bring a “newbie” to the range. Make it a great experience for them!
Ever hear of a “Curio and Relic” license? The ATF issues various “types” of licenses depending upon the business or purpose. “C&R” licenses are type “3.” It is a federal firearms license (FFL) issued by the ATF specifically designed for people who may collect older firearms such as military long guns or pistols.
So, what does that mean to you? Well, it means that if you apply and are granted a C&R license, you can directly receive C&R firearms from a seller without having to meet with a FFL to do a transfer. And, the fee for the license is only $35 for three years!
What is a ‘curio and relic’ firearm? It is one that meets the following:
A regulation implementing Federal firearms laws, 27 CFR §478.11, defines Curio or Relic (C&R) firearms as those which are of special interest to collectors by reason of some quality other than is associated with firearms intended for sporting use or as offensive or defensive weapons.
To be recognized as C&R items, 478.11 specifies that firearms must fall within one of the following categories:
Firearms which were manufactured at least 50 years prior to the current date, but not including replicas of such firearms;
Firearms which are certified by the curator of a municipal, State, or Federal museum which exhibits firearms to be curios or relics of museum interest; and
Any other firearms which derive a substantial part of their monetary value from the fact that they are novel, rare, bizarre, or because of their association with some historical figure, period, or event.
Firearms automatically attain C&R status when they are 50 years old. Any firearm that is at least 50 years old, and in its original configuration, would qualify as a C&R firearm.
Applying for a C&R license is similar to any other license application, except certain steps are waived (such as an on-site, in-person interview and a photograph). The ATF notes on the application instructions that:
It must be emphasized that the collector’s license being applied for pertains exclusively to firearms classified as curios and relics, and its purpose is to facilitate a personal collection. You may NOT engage in the business of buying and selling any type of firearm with a type 03 license.
Ever heard of a pistol or a rifle “short-stroking?” No, it has nothing to do with the 1981 hit single “The Stroke” by Billy Squire (what was that all about, anyway?) Firearms are said to “short-stroke” when the bolt (or slide) does not travel far enough rear-ward to eject the spent case, cock the firing mechanism, and chamber a new round. Technically, short-stroking can occur with any action (yes, even manual bolt-action rifles – think about it.) but it is most associated with semi-automatic and automatic firearms. This short Youtube video shows a couple good examples of short-stroking.
So, why my interest in sharing about short-stroking? I was at the range shooting my gas-impingement AR the other day. I planned to shoot 40 rounds, in two magazines of 20 rounds per. First magazine, no problems. Shot it pretty well for a guy with older eyes. Second magazine… problems. The bolt stopped cycling at all (the no-stroke!) I could manually operate the charging handle to eject the case and chamber a new round, turning my nice AR into a bolt action rifle. Like most people, since the first magazine had worked and the second did not, I figured “bad mag” or “something broke.” Let the diagnosing begin.
Ok, specifically with short-stroking, what can go wrong? Remember, the bolt is not traveling far enough rear-ward to eject the spent case, cock the firing mechanism, and chamber a new round. Therefore, bolt can be obstructed, something can be slowing the bolt down (too much) as it travels rear-ward, or the bolt isn’t getting enough “push” from gas or the piston. Why this is happening can be explained by a few hundred things (that’s an exaggeration. For those of you that know me, I like to stick to the most likely.) However, if you are interested in a lively discussion many of the possibilities, check out this thread from Calguns.
Most of the time, short-stroke problems are caused by insufficient gas to operate the piston or bolt. Let’s assume we have a gas impingement system and we have two fully functional AR’s (because one is never enough, right?) Not enough gas could be caused by:
Something wrong with the bolt/ bolt carrier (gas rings, gas key, bolt and/ or carrier ports)
Something wrong with the gas tube (separated from the gas block, kinked, broken)
Something wrong with the gas block (shifted off the port)
Something wrong with the gas port (plugged or too small)
As with anything on the internet, you perform any of the actions in this article at your own risk. I specifically suggest that people who are not qualified to work on firearms bring them to a qualified armorer or gunsmith.
That being said, here’s a quick way to diagnose the issue.
Swap the bolts/ carriers in the ARs. NOTE – there is some risk here. It is possible (but not likely with mil-spec ARs that are chambered for the same round (e.g., 5.56)) there may be a head space problem with swapping the bolts. If you are not sure, SKIP THIS STEP. Do they both work? Yes? Not the bolt/ carrier. Does one work and not the other? You’re right, it’s the bolt/ carrier. Check the key, the rings, and the ports.
Visually inspect the gas tube. Is it connected to the gas block? Is it noticeably bent, kinked, or broken? Is the gas tube pin still securely in the gas block?
Check the gas block. Is it installed permanently (e.g., as in some A2 gas block/ front-sight) or is it a “low profile” block installed with set screws. If it is not permanently installed, the gas block may have shifted. In the case of the set screws, this is probable, especially if the barrel was not dimpled and/ or the screws were not set with a thread-locker. Look for discoloration around the base of the gas block and the barrel. If you see it, gas is escaping, and that isn’t good.
Check the gas port. Attach a small piece of rubber tubing to the end of the gas tube in the upper. Blow through the tube and listen to learn if any air comes out of the gas port in the barrel. If so, that’s good. If not, the port is misaligned with the gas block or the port has become obstructed.
My guess is that one of these checks will help you quickly find the issue.
My problem? I started simple and checked the mags. You already know that the vast majority of feeding and ejection problems are related to magazines. Not enough “spring,” too much “spring,” bent feed lips, bad mojo, whatever. No problems, though. Both were factory Colt and both were in good shape. Both worked Ok in my other AR. Not the mags. I swapped the bolts/ carriers, no issues.
Moving along to the gas system. For this AR, I had purchased a complete upper from a manufacturer with a low-profile gas block and a free-float quad rail. Off with the rail so I could look at the gas block. Lots of discoloration and it seemed to have moved forward towards the muzzle. The block was installed with set screws. No dimples, no thread locker. In fact, looking more closely and shifting the block a little, the gas block had shifted forward nearly choking off the gas port. Ah, simple. Completely remove the set screws and realign the gas block and gas port. Use thread locker to reinstall set screws.
Time to test fire. Load and insert a mag with two rounds. Manually chamber. Bang. Good ejection. Good chamber. Bang. Good ejection. Lock back on empty mag. Fixed! Re-install rail. Get a beverage.
That’s my story on my short-stroke adventure. If you have any similar issues, this may help you get to the bottom of them. Or, you can always give me a call.
Opinions are in no short supply when the topic is using “steel cased” ammunition. Steel cased ammunition is exactly what it sounds like: the case is made of steel rather than brass. Many cartridges manufactured overseas use steel for their cartridges. Some brand names you may recognize are Wolf, Brown Bear, and many of the imported surplus cartridges.
My personal experience has been that steel cased ammunition “runs dirtier” than brass. Not only is this due to the type of powder, but the fact that steel expands at a slower rate than brass. So, when the cartridge is fired, more gasses and carbon can “leak” around a steel case as the case expands and seals against the chamber wall. This would tend to foul the breech face and, perhaps, other parts of your gun, more than brass cases.
Of course, steel-cased ammunition is usually somewhat cheaper than brass-cased. So, a little more cleaning may be worth a lower price per round, right?
Well, maybe. Assuming you do a good field strip cleaning on a regular basis, maybe it’s a good deal. A detail strip may be needed more often if the ammo is running dirtier.
The real question is… will it hurt my gun? My thought is that it probably won’t hurt your barrel or chamber. Some wear may be associated with the extra fouling (at least the fouling I experienced).
The biggest concern I have with steel-cased ammunition is with semi-automatic firearms and the wear on the extractor. The head of the extractor slams around the case lip every time a round is chambered. I know brass is softer than steel so the wear on the extractor would likely be less than if the round was steel-cased. And, based upon my experience, the first part to fail in any semi-auto gun is usually the extractor.
So, for me, it is brass-cased ammunition in my non-Eastern European guns.
Opinions vary. Below is a link and a video giving two other opinions on the use steel-cased ammunition. Very interesting information. Decide for yourself!
