Range Report on M4 Carbine

I’ve had an LWRC Carbine for several years now and it has served me well.   I’m not going to brag about  how great this thing runs compared to other firearms, all I’m going to say is that this was the gun I really learned about gunsmithing with.   I recently stripped the gun down to do a repair after the stock came loose and i lost the rear take down pin detent and spring.   I was shooting and noticed that my M4 Carbine rifle stock was starting to unwind and I was a little surprised.  I thought I broke the stock for a moment and then I realized that it was just lose.  I didn’t have a stock tool with me so i just hand tightened it, but then I noticed the rear take down pin was falling out.

Well, I wasn’t in a gunfight, but I did learn that more than just an optic or a magazine can fail you, you’re gun may just fall apart if you don’t pay attention to it.   While I took the gun apart to analyze it a little more I notice that the fore grip that I was using was cracked, it had not broken off on me, but man, did it look like it was close to snapping, there are a great many things to lock down and tighten, spending $1800 on LWRC uppers, doesn’t mean the gun isn’t allowed to have an operator induced failure of some sort or sheer neglect.   Everything that can come loose needs to be checked.

The Beauty of owning an AR15 Carbine

There was a time when I bashed the AR15 time every time I heard somebody rave about them, but that part of my outlook on the design has ended.    The differences between AR15 rifles as varying as the differences between cars.  You can get a compact car, pickup truck, van or monster truck and they all basically work the same on the outside, they roll, drive and turn, but internally they can be different and they all have different operating purposes.   The AR15 upper receivers you see now can be direct impingement, piston driven, 22 caliber converted, 6.8 SPC, 50 Beowulf, and on and on.  I can’t back it up, but I’ve read there are up to 40 different calibers you can get them in.   I really only could ever seen the need for 3 or 4 of them, but the design is so well received, that there is still plenty of new things to come for the design.

I have always been a fan of piston guns and not direct impingement.  Modern technology has made firearms more reliable even if they are still DI guns and arguments about gun reliability really only get blamed on the operator and not the designs.  If you want to compare an M16A1 to a piston driven gun it’ll be a slaughter over reliability, but AR15 really give you what you pay for them.   I am an LWRCI upper receivers fan.   If you still have an old Bushmaster DI gun laying around and wants something really different, you gotta spend the dough, but it’s fun with less cleaning time.  If I think of the last 20 times I went shooting, and did no more than 10 minutes of cleaning each time, I’ve saved hours of slopping gun cleaner around.  Gun cleaning supplies don’t cost much, but if you shoot often and clean your guns,  you will save time and money on just those things as well as bolt carrier life ect by switching to a n LWRCI upper receiver.

Long range shooting with an AR platform rifle

I don’t know all of the facts and figures, but given just what I see every day on the New York and Ohio firing ranges around here, I would say that the AR15 is the most popular rifle in America.   Now that caliber changes are as easy as swapping out your AR15 upper receiver and possible only a minor change in your lower receiver like a hammer spring, you can go from a .223 varmint rifle to a 6.8 SPC rifle, or down to a CQB rifle at almost the pop of two pins.   I was never a big fan of upping the caliber on a AR15 rifle, but I am a big fan of the 75gr HPBT for close up fighting.   The 75gr bullet seems to yaw better and slower velocities and give more thump just from my experiences.

When it comes to taking your AR15 rifle to a longer range, there are records being broken every week with the AR15 platform.  People use to laugh when they would hear of some one shooting an AR15 at 1000yds,  but it is done and can give a .308 a run for it’s money.   The real thing to consider when it comes to caliber changes on AR15 upper receivers  is how powerful is the round vs just accuracy competitions.   I have a friend that came back from service over in the Middle East and he gave first hand accounts of how bad 9mm ammo was in combat and that at least 3rds of M855 was necessary to take down a threat with an M4.   Consider the ammunition you are using and not just how far out you can shoot, you may want to trade accuracy for energy.
