A quick down and dirty on zeroing a carbine
Kyle,Good video on zeroing a carbine. I have a new M4 that I want to put some rounds through. First activity will be to dial in the weapon.
Kyle,Quick question on carbines. Is there any danger in leaving a 30 round magazine loaded for extended periods of time? Say, I have some magazines loaded, but don't end up going to the range for a month or two. Am I risking the integrity of the magazine spring?Thanks!Josh
Not after a month. Compressing the spring isn't what wears it out, cycling it is. You can leave mags loaded for years and as long as they're quality mags, you'll have trouble free service. If you're using P-Mags, use the caps for long term storage. They push the top round down so it's not resting on the feed lips for long periods of time.
What Haji said plus:I personally don't load more than 28. That way you'll never accidently put 31 rounds in a alum GI mag (which will hold 31 after some use. That's the number one reason people mess up the feed lips (especially on soft aluminum)is continually putting that extra round in. Even if you realize it, the damage is already done. Tac reloads are easier as well with 28.Also, it's been my experience that any magazine colored tan is weaker in the long run. This counts for the brown Brownell's mags, and the tan P-Mags. The latter I've personally seen in the last two weeks push the feed lip into the chamber after being taken out of the package and being used for 2 days of carbine work (maybe 200 rds total). I beleive it to be the ingrediant they use to turn the color tan (it comes natural black I'm told).Last tip. To ensure you've loaded 28 rounds; top round on right side, push down and that top round should line up with the square "U" shaped cut out on the spine of the magazine.
Sorry that was me above,Kyle
Kyle and Haji,Thank you very much for the feedback!Josh
Man, I must be gettin' old. I should have mentioned downloading, but I fergitted all about it. That's why Kyle Defoor gets paid to teach people what he knows, and my free advice is worth the price.I was watching the SOF Three Gun match near Ft. Campbell a while back. There was a stage that had a required reload before the second part of the stage could be engaged. Those that loaded all their mags to 30 rds had the same problem: when they tried to jam the mag in on a closed bolt, it didn't latch and fell out. In the match that just costs time, but it could be a whole lot worse under other conditions. I'm not aware of a 30 round mag that will reliably lock into a carbine on a closed bolt. I guess one either finds a way to never put in a mag on a closed bolt, or learns to load 28. :)
Kyle,Excellent video. What earpro are you using in this video, and how do you like them? They look like some form of Surefire.Thanks,Jason
They are Surefire. I love Surefire to death, but, I don't much care for these plugs. We use them because they are less noticeable than other choices. However, you'd be hard pressed to wear them for a day of shooting carbine. Pistol, maybe. You'll notice we wear electronic when we shoot the big calibers and do house work.Kyle
correct on the tan mags, I have one tan and the rest black, the tan one is just a tad more flex to it and you can even see that the texture is different. colored mags are cool, but you can always paint them the color you want. thus maintaining integrity. plus when they get used a bit and some of the paint gets scraped off, they look really cool. which you know, of course helps performance if it looks cooler than the other guys gear...
Kyle thank you for the video. I am converting to a 100 yard zero from using a 50 yard zero the last couple years. One question I have is about group size. I know you want the smallest size group possible but what is acceptable size group at 100 yards/meters? I run irons and an Aimpoint CompM3 on my patrol rifle. Thanks,Stan
