We have not forgotten.
An odd issue, the round managed to slide forwards and the large rim of the 7.62x54R held it in place in the lower. The round had to be hammered out. No matter how simple the machine, there can be issues that take it out of commission.
Additionally last weekend we has an out of battery (OOB) detonation destroy a Walther G2 rifle. While the rare .22 OOB does little to a Ruger 10/22 or an AR15 conversion kit, these little pot metal plinkers that Walter is sell can not seem to survive them well. I would recommend to pay a little more and get a more durable firearm. Consider it an investment.
On that note, fortunately the owner of the firearm was wearing his eye protection as the top of the rifle was broken. Often at the range we have a hard time getting people to consistently wear their eye protection. Some even get offended when we tell them to do so. I shouldn’t have to explain to people that eye protection is necessary for so many reasons. From kabooms to richochetes, there are so many good reasons to wear eye protection and no acceptable excuses. If you say your eye-pro makes your S&B look like a NCStar, buy higher quality eye protection, you can afford it. Should you think that eye-pro makes you look un-cool, would an eye patch look better? I dunno, perhaps some people would like the pirate look. If possible, wear wrap around eye ballistic protection, while prescription glasses or sun glasses are better then nothing, they pale in comparision to the better protection quality ballistic eye protection will give you. Your eyes are worth it.
Oh, and when you are at a public range, it is good to pay attention. Not paying attention and doing things like going down range while the line is still hot is not generally a good idea.
To preface this, let me state that I served in the Marine Corps as a rifleman and that I carried a FN M16A4 in Iraq. The above picture is of the rifle I carried in Iraq.
I see online that some people have a hardcore love for the M16A4. In reality, it is not that good. Please don’t get me wrong it isn’t a bad rifle, but it is not a great one.
When considering the M16A4 uses as a combat rifle it is ok, but not as flexible as a M4. If you employ the M16A4 as a battle rifle, like the M1Garand, M14, and M16A2 that preceded it, it is great. However a battle rifle is not suited for all combat. The longer length of the M16A2 & M16A4 along with the fixed stock, makes for a less then ideal rifle for close quarters battle or for use with body armor. Its’ 40 inches of length makes the rifle more awkward when egressing vehicles.
The main benefits of the M16A4 over the M4 are higher muzzle velocity and longer sight radius. The benefits of increased sight radius are negated if we use optics. While more velocity is always nice, it is shot placement and bullet selection that is very important. Outside the military, we are not limited to M855 ball ammunition, and there are plenty of alternative that will function excellently in shorter barrels.
For a civilian, I can see why someone would want to reproduce a military rifle. However from a cost effectiveness standpoint, building a M16A4 clone is silly. Few companies make M16A4 style uppers, and there is good reason for that; they just don’t sell well. The Knights M5 RAS quad rail used on the rifle runs about $320 dollars new. For far less then that you can get a lighter, cheaper, free float rail. The Government profile of the M16A4 combined with a heavy non-freefloat rail does not make for the best accuracy or consistency. A proper M16A4 clone is neither accuracy enough for precision competition, nor as handy as a M4 style carbine.
While I was in the Corps, there was a big mentality that the M4 was just such an inferior weapon system. I believed this for a long time, till finally I started to realized that if the entire Army was fielding M4s, it can’t be junk. However our Army does make mistakes, but other groups like the SEALs, some of the British, German, Irish, and Australian special forces, etc. Many elite forces around the world choose the M4 or variants(like the C8SFW) for their mission over their own countries standard issue rifle, or full length M16s. Clearly the M4 has the reliability and capability for those end users mission.
The M16A4 is a battle rifle, however the M4 carbine is a versatile jack of all trades that is better choice for most individuals.

Last Sunday I helped a shooter at the range with a brass over bolt malfunction. Brass over Bolt is a rare malfunction where a casing(live or spent) gets stuck over the bolt and between it and the charging handle. I’ve learned that the quickest way to clear one of these jams is to reach up in the mag well with your middle finger and put that finger on the bolt face holding it back. When that bolt carrier group is held back, you can run the charging handle forward, and knock the stuck casing/round free.
Shawn and I both agree that while the brass over bolt malfunction can be cleared quickly, in a faster paced or close range fight you may be better off transition to a sidearm if you have one available to you.
While I was in the Marines with all these used and abused M16A2 & M16A4s and old worn out mags and we never saw or heard of a brass over bolt malfunction. Now the funny thing is, every time I have helped someone with a brass over bolt malfunction I noticed they they were not using cheap or worn mags, they were using Magpul PMags. I have discussed with Shawn and he too noted that brass over bolt malfunctions seem to be rather new, and seem to mainly have happened in AR15s using PMags.
So, have any of you had the brass over bolt malfunction and what mags were you using when you had it?
