I have seen many arguments online about the necessity of back up sights on a rifle using optics. The general concensious seems to be that they are needed on military rifles, but not on civilian rifles. This is not the case.
In the military people work in teams and are almost never alone. Should a rifle go down it is not really an issue as you still have many other people capable of continuing the fight. For the civilian and the police officer this is often not the same. If someone wakes up in their home and finds the battery dead in their reflex sighted rifle it helps to have iron sights. However if a Marine’s optics fails, he is only reducing his squads fighting ability by 1/13 its firepower.
So do you need back up irons? First needs to consider if the rifle is a toy, or a tool for fighting. If it is a toy, back up sights are not necessary. If it is a fighting tool, look at its role and how it is set up. If you are running battery powered optics or magnified optics on quick detach mounts, I would suggest back up sights. So if you need to use a wrench to remove your optic, back up sights may not be practical for you and you may be better off switching to a different weapon.
“Damn, the batteries are dead.” Is not an uncommon saying at the range I work at. Not only among cheap optics with poor battery life, but often about Eotechs. Batteries discharge, cheap batteries and cheap optics drain even faster. Even the best optics can be broken. On the range this is just an annoyance, for the Soldier or Marine it means that their buddies will have to take up the slack. However if you, as a lone civilian or law enforcement officer, have this happen in the fight, the results can be costly.
I highly recommend back up sights on the individuals fighting rifle. If you are fighting by your self, being able to keep your weapon in the fight is crucial.
On that note, also make sure to keep your back up sights zeroed.
This video is a reminder of the results from not being ready for a fight when it happens, and not making sure to always keep your side arm in condition 1. Not only did the would be hero get shot, but he lost his gun to the bad guys and if they got away its likely they will use or already have used it on some one new.
Today an Out Of Battery (OOB) failure, in a P22 with Remington ammo, broke the frame and sprayed debris into the shooters face. Fortunately the boy who was shooting this pistol was wearing his eye protection.
Now that the magpul DVDs have been out for a while and it seems everyone has seen them, I have noticed a few common ideas about them people seem to have especially on internet forums. A lot of people I talk to about them seem to miss some of what I think is the real point and value of them. they obviously can not substitute for real hands on training, but they do have some real benefit despite what some say. Mainly I think the point lost on a lot of people is the video really help with weapons handling and manipulation. Even if you are a long time AR15 user, you can learn some pretty good stuff, even if you do not adopt their procedures it gets you thinking ( if you have enough brain) about cleaning up your own sloppy actions.
If you do choose to use their version of each operation its still some good stuff. Its in style now to rag on them and make all the useless and pointless tier 1 jokes in a worn out attempt to be sarcastic, but in doing so, some real chances to learn are lost. I for one have become a lot smoother with my weapons manipulations and have even modified some of what they teach to better fit me. You do not have to do it exactly their way but it is a great starting point for basic manipulations and smoothing your own self out.
Another thing people seem to get the wrong idea bout is speed, or how fast they can put 5-10-20 whatever rounds out. We have seen a lot of guys shooting at ranges who seem to think the point is to get the mag half empty in 3 seconds even if they hit the dirt 5 feet in front of them!! The videos do not demand 1 MOA groups on target, but a balance between speed and accuracy that is good but not slowfire at the NM good. But it seems that because it is so cool to see those two guys dumping rounds on target in seconds people just forget you also need to actually hit with those rounds. The more the offender seems to blaze away at a break neck speed, the worse they were at just plain marksmanship to start with. The idea being forget precise shooting I will just do a mag dump! Few seem to want to train smooth a slow so they never gain the speed that comes through the repeated movements done correctly.
