我最近也在挖MK13的资料，空白巨多，特别是Stiller的MOD6和MOD7。记得2010年Stiller拿到NSW的Crane的合同，很模糊地说是S家要给新的MK13提供枪机，但相当模糊，不知道到底是提供的雷鸣顿700枪机还是Stiller自家的。

还有一个是现役
其实SFG私货多也是有原因的。NSW有crane拦着，啥私货都是他们先试了再说，反正Crane批准了的东西也还算有保障，何况现在整个NSW现役人员都不得参加shot show了，想私下搞搞难度也增大了。Ranger呢，跟着CAG大哥混，反正是亏待不了他们，用大哥用剩下的就好。air force的大爷们我就不说了。好吧就剩下MARSOC跟SFG了，MARSOC问题比较复杂就不谈了。剩下的SFG虽然没啥钱，但是对试用装备这事也就睁眼闭眼了。
SFG目前是土豪G跟屌丝G待遇差距不小，7th SFG其实已经属于土豪G了，上次南美比赛几个AR就没两把一样的配置。像这次的话，有人是自己掏钱买的Reaper机匣，有人是单位发的，SMU发整枪我就不说啥了。顺便一说，JPC和CPC现在基本上也都是公发了，你看哪个SFG没有的，那就是个屌丝G。
SOPMOD 2其实是基层抱怨还是相当多的，比如DD的管子不耐操，eotech 553和幽灵瞄各有问题，M3X也不是啥好灯，何况SOF们想要mid-length很久了，这次也算是忍无可忍了。

倒不是故障，复进簧太软的话枪机会复进不到位，特别是当枪机比较脏的时候。Mike Pannone就是换个更硬的复进簧，用更大的力气去推枪机，确保它复进到位。当然，这个也是有它的缺点的，太硬又会导致枪机不能完成一次循环。

Mike Pannone - The Big M4 Myth: "Fouling caused by the direct impingement gas system makes the M4/M4A1 Carbine unreliable."

Here’s my question for those that subscribe to the direct impingement fouling concept:

I fired 2400 rounds of M193 through a 14.5” M4-type upper receiver from Bravo Company Manufacturing (BCM) with no lubrication, and without any rifle-caused malfunctions. So; why can I get my direct impingement rifles to repeatedly do things that conventional wisdom says they can’t do?

This article is not a direct impingement vs. piston driven operating system debate and does not discuss piston guns at all. It is specifically dealing with a 14.5”AR-15 upper receiver with .062” gas port that’s as close to a Mil-Spec M4/M4A1 upper as I could find on the civilian market.

All I have ever asked and required of myself (and others) as a professional is that everything I say or write must be capable of being substantiated. I am asking some questions and giving my opinions, observations, and conclusions based on my own experience and testing.

For years I have been told, and heard others repeat, incessantly, that the direct-gas-impingement M16/M4 family of weapons is flawed because they deposit gas and powder residue in the upper receiver, and thereby are inherently unreliable with hard use. That sounds good in theory. However, in practice, I have not seen nor experienced it with my guns as a special operations soldier or civilian instructor. Why is that? Why don’t I have said commonly referred-to fouling problem with even excessive use and minimum maintenance?

When I returned from Iraq in 2005, I was a primary instructor on a rifle course with the Asymmetric Warfare Group (AWG). During that time as I have mentioned in previous articles I began a quest to find out what made the M4/M4A1 Carbine run well, and what stopped it from doing so. In that time I spent a year at the 82nd Airborne Division training with infantry units prior to their deployment on the Iraq surge. During this time, I saw every manner of malfunction and never saw a rifle that was not well cared for (the soldiers attending were more senior and specially selected, as well as being members of the highly disciplined 82nd Airborne division). Each time there was a malfunction, if possible, I would run over and observe what had happened, then write it down in my log book. What I eventually realized was that when magazine issues were removed, along with broken parts, about 80% of the malfunctions had been accounted for. The rest were failures to properly extract and eject, and failures to go into battery. That is where I realized my rifles were superior to the ones issued. The only problems I had experienced with my own guns were double feeds which are exclusively magazine caused.

What’s odd is that I was using a civilian version of an M4 that was nearly identical to the ones used by the paratroopers of the 82nd. My rifle utilized a chrome-lined 16” M4-profile barrel with a free-float forend rail tube. After that barrel was shot out I went to a Noveske 14.5” Afghan barrel, and then finally to a Noveske 14.5” N4 cold hammer forged, double-chrome-lined barrel. Aside from being semi-auto-only instead of select-fire (i.e. burst-fire or full-auto capable), and one having a barrel that was 16.1” vs. 14.5”, they were functionally the same rifle. The difference was that I used a heavier Sprinco buffer spring (correctly called an action spring), a Extra-heavy buffer (.2oz lighter than a Colt H3 buffer), and a 5 coil extractor spring with a Crane O-ring for added extractor tension. Those drop-in parts made my rifles obscenely reliable, and still do. The spring-and-buffer combo I use works in mil-spec-size gas port rifles (.062” as per NAVSEA Crane a.k.a. Naval Surface Warfare Center, Crane Division) with 14.5” or 16” barrels and a 7.5” carbine gas system. There are some rifles on the market that have smaller gas ports than the Colt M4 in its military configuration, so the spring and weight may not work in them, as they may cause short cycling issues. I had the luxury of shooting my rifle without maintenance in a training environment until it failed. I routinely went well over 2500 rounds with only a few drops of oil and a bore snake run through the barrel every morning. I was convinced there and then that fouling was not nearly the issue it was purported to be, and that the real issue was weak springs and a buffer that was too light.

My Test:

Recently, I received a milspec equivalent (barrel length/gas port size/gas system length) M4-type upper from Bravo Company USA (BCM) to test my theory that a heavier buffer and spring with enhanced extractor tension would give extraordinary reliability with no lubrication or maintenance whatsoever. I have shot over 2500 rounds with the FailZero kit with EXO Technology coating on four separate occasions with no lubricant, as well as a ceramic coated rifle (to include bolt and bolt carrier group) from Next Generation Arms that currently has 4000 rounds on it without cleaning or lubricant, and also no malfunctions. I have also routinely shot a Noveske N4 14.5”-barreled rifle over 2500 rds with only 6-8 drops of oil every 500-700rds fired without any issues. If I used those rifles or parts for my test, many would say “well those are custom coatings/guns and military guns don’t have that.” For that reason, BCM was kind enough to send me a stock 14.5” upper on which to do the test.

Prior to the test I did the following:

1. Remove all visible oil and lubricant from the inside of the upper receiver.

2. Disassemble the bolt carrier group (BCG) and remove all lubricant inside and out

3. Put a Crane O-ring on the existing extractor spring

4. Use a lower receiver with a Sprinco standard Blue spring and an H-3 buffer (I used an H3 because it was close to the Extra-heavy buffer I use in most of my rifles.

After I had done that, I fired 2400 rounds of M193 through it in six sessions, often shooting it so hot that I could not hold the forend without gloves. The first of such sessions was in the presence of two Border Patrol BORTAC snipers, and it consisted of 330 rounds in 25 minutes. This included zeroing the optic so the bulk of the rounds were fired in a 20 minute period by all three of us. (Note: At the conclusion of this, I pulled the bolt carrier group out and held it by the lugs with my bare fingers. That’s another myth (to debunk) for another article. I did this a second time later during the test where I had shot the rifle so hot I needed gloves to hold the forend, then shot 120 rds in 2:35 and again held the bolt by the lugs with bare fingers.) The rifle had no issues other than some test magazines that did not feed the last round properly. Once those test magazines were removed, the rifle always locked to the rear on the last round fired and did not feel sluggish.

With good magazines–I used USGI aluminum of various makes so as to replicate military use as closely as possible–there were no issues until I reached 2450 rounds fired. At 2450 rounds the rifle would not complete the recoil cycle due to the additional friction caused by the fouling and no lubrication, and exacerbated by the extra buffer weight. Once the rifle began short cycling, it did so every shot. In diving medicine, that’s called “dramatic onset of a symptom”. It was as though a switch had been flipped and the rifle just stopped working.

Rounds fired per session were: 330, 510, 540, 450, 450, 120* (Note: Failure point was end of 6th magazine/2440rds. Problem: chronic short cycling due to excessive fouling caused friction.)

At the failure point I replaced the H3 buffer with an H buffer, and the rifle ran reliably again. I finished the remaining rounds in the 6th magazine of the session, and continued shooting. At 2500 rounds, the rifle ran, although quite sluggish in counter recoil. Then, nearly on cue, the rifle stopped again, this time at the 2540 round mark, and the last ten rounds were accomplished by tap-rack (performing a tap-rack-bang drill) each time. Just to isolate the issue I put the BCG in another dirty but oiled upper of same design and it ran easily (with H3 buffer reinstalled). I returned the BCG to the original upper, oiled it, and the rifle immediately came back to life firing another 90 rounds smoothly and without issue (2630 total rounds fired for test + 30 in replacement receiver cited above).

Here are the findings of my testing:

· When the rifles become fouled, they have more drag (friction) inside the upper receiver, which slows down the bolt carrier group. This along with the pressure on the bottom of the bolt carrier from a loaded magazine will slow the BCG down enough to keep it from reliably going into battery during the counter-recoil cycle. The heavier buffer and spring completely remedy this, but there is a crossover point. That crossover point on a bone-dry stock M4/M4A1-type AR carbine upper is about 2400rounds fired. At that point, if there is enough buffer spring tension to drive the BCG into battery, then it cannot fully cycle. And, if the spring is light enough to allow the weapon to fully cycle to the rear, it does not have enough force to go fully into battery. The changing from an H to an H3 buffer only gave an additional 80 rounds of reliability. And, given the parameters of the test (no lube) and the dramatic increase in shootability using a heavier buffer, I am still a proponent of a buffer heavier than an H.

· With the Sprinco enhanced Blue action spring (or comparable extra-power spring) and an H2 orH3 buffer, unless there is a rigid obstruction present in the barrel extension, the rifle will reliably go into battery. Note: I routinely take “damaged” or discarded rounds (see first article on M4 reliability) that have been lying around or have deformed cases from the malfunctions block I conduct and load them into my magazines. I will shoot them all without issue, unless they are catastrophically disfigured or the projectile is pushed back into the case (creating a safety issue due to increased chamber pressure). The heavier buffer and added spring tension effectively resizes the case and fires it.
· A benefit of the additional spring/buffer weight is that it slows down the unlocking and extracting tempo, increasing the locked chamber dwell time and allowing for much more reliable extraction and ejection. This is because the longer dwell time allows the chamber pressure to recede more, as well as transferring heat from the case to the chamber walls. It also offers a softer-shooting rifle because the recoil impulse is transmitted over a longer period of time, hence lower ft-lbs/second received at the shoulder.

· With an enhanced extractor spring (BCM 4 coil, Sprinco 5 coil or comparable) and a Crane O-ring, I have not experienced any failures to extract except for faulty ammunition (specifically Radway Green training ammunition used by the 82nd in 2006) The SOPMOD bolt upgrade kit (new extractor and pin, 5 coil extractor spring, Crane O-ring and new gas rings), first fielded by SOCOM, should be standard on all M4’s used by the military or law enforcement.

Conclusion:

Fouling in the M4 is not the problem. The problem is weak springs (buffer and extractor), as well as light buffer weights (H vs. H2 or H3). With the abovementioned drop-in parts, the M4 is as reliable as any weapon I have ever fired, and I have fired probably every military-issue assault rifle fielded worldwide in the last 60 years as a Special Forces Weapons Sergeant (18B). An additional benefit of the heavier spring/weight combo is that it transmits the energy impulse of the firing cycle to the shoulder over a longer duration, lowering the amount of foot pounds per second and dramatically reducing the perceived recoil. Follow-on shots are easier to make effectively, and much faster, especially at 50 meters and beyond.

I reliably fired 2400 rounds (80 magazines) on a bone dry gun, and I would bet that is a lot more than any soldier or other armed professional will ever come close to firing without any lubrication whatsoever. So, disregard the fouling myth and install a better buffer spring, H2 buffer, enhanced extractor spring and a Crane O-ring (all end user drop-in parts). With normal (read “not excessive”) lubrication and maintenance, properly-built AR-15/M4 type rifles with carbine gas systems will astound you with their reliability and shootability.

这种短瞄1到4倍转换非常容易，不少也自带”红点“功能(无论是靠电池还是别的）。一个镜就能解决问题的话当然是最好的。
幽灵瞄嘛，SMU基本上没人用，因为其实不好用也不耐用，传统光瞄在成像上和可靠性上更有优势。主贴里最后那张图，你可以看到特种部队的侦察狙击小队那支16寸的RECCE就是用S&B的短瞄。
