High Exposure

Call Walmart and ask for a price adjustment.

He may have built 10+ ARs but he sure doesn't know how to compensate for mechanical offset at 20'.... Also, he said the headspace was a tad tight, but the gun still functioned.

The only time I check headspace is if I am installing a new bolt or bolt carrier group into a used upper. I always check, but I have never gotten a no-go... I don't check on a new build, but I use quality parts that I know have good QC. If I used a BCG I bought from Uncle Cheech's Tactical Warehouse on EBay and were mating it with some kind of "Death Dealer LLC" barrel I picked up at a gunshow, would probably check headspace.

That's really you? I thought it was Jim Norton. :rofl:

I see this a lot. Loose shit on a rifle is now the first thing I look for when troubleshooting someone's issue. Get a paint pen and put witness marks on all of your screws, bolts, etc... That way you have a visual indicator if something is off and don't have to get a bunch of tools to check everything to make sure it is snug.

That's what Jon always said. I spent all last Sunday watching him shoot one.... Just sayin...

Windage and elevation adjustment indications on sights are for bullet strike. If you want your bullet strike to move up, follow the UP indicator (or go opposite from the DOWN indicator) on your optic/sight. Same for RIGHT/LEFT. You instinct was right. If your bullet is striking the target above the point of aim, you want to follow the DOWN indicator arrow on your elevation adjustment to lower the bullet strike into your point of aim. Don't think about moving your aiming point, think of everything in terms of where you want your bullet to go.

Damn your black heart Vlad..... I just ordered a case of Fiocchi 7/8oz slugs and two chamber flags for my long guns. I am looking at shotshell carriers and a Beretta 1301 shotgun, for my next purchases and have been watching 3-Gun vids when no one is looking...

I personally think it's another stupid izzy device and Checko should clearly be ashamed that he bought one I remember someone telling me once, that they use these as a friend/foe indicator in Isreal for plainclothes guys on VIP details. They have a color of the day so to speak and everyone uses the same color skin on their pistol. If something happens and guns come out, anyone not have a gun matching said color is a bad guy. Smart in principal, stupid in execution, but it lets many different people from different units that are essentially strangers support each other safely if necessary.

^^^ everything Shawn has said in this thread so far. I can't believe that the NRA lets you teach people.... Regardless of EOTech, irons, Aimpoint, or ACOG, your lack of understanding of basic marksmanship principles and how to use them in the real world is astounding. I award you no points, and may God have mercy on your soul.

Yes. The old EOs had an issue with recoil killing the springs in the battery box that constituted the battery contacts. So they turned the battery 90 degrees to alleviate the issue, and the EXPS line was born. The problem with that is CR123 batteries are not designed to take recoil impulses along the short axis, they are designed to take shocks along the long axis. Repeated force of recoil exerted to the short axis abuses batteries. I have seen batteries swell so much they couldn't be removed without surgical tools. I have so seen batteries burst in the battery box with the resulting mess and killing of the optic until it is returned for repairs.

I have had the same experimce as Vlad. I had an EO (it lives on a .22 AR trainer now - not on something life saving) and our team used to issue EOs on duty guns. We had many many issues with them. Now we issue PROs. I have seen a brand new EO not last through T1 of a 3 day class when it's battery box shit the bed. The optic was a total loss. As far as I know, Mark only has that optics on his rifle because he spends $$ on his other toys and can afford to replace it and he has had extraordinary luck with it running. Also he is fastidious with his gear and capable of making repairs to the major EOTech killing culprits on his own.

Control where and when they die and you can control when and where they turn - ergo offering a chance to prevent their turning after death at all.

Head shots are hard. Under stress, on a moving target, even harder. Training snipers takes time. You can't train an entire army division to be snipers (which will take a lot of time) and task them to secure portions of an overrun city at the same time.

We won't see the cold, but the inside of a car can easily get to +122F in the summer. Once the shift occurs, my understanding is the rifle has lost zero. This POI shift is also in addition to the other multitude of issues the EOTech has - from battery life, to the engineering of the battery box.

None of this should come as a surprise. The issues with this optic has been discussed for quite some time. Some points to consider while perusing: All optics have parallax to some degree regardless of what the manufacturer's clams are - yes, even Aimpoint. RDS are not precision instruments The again, neither is the M4 carbine, M855 Ball (or most any ammo generally fed to a standard carbine), or - and this is the most important factor - the an overwhelming number of end users There is always, to some extent or another, some +/- in adjustments Note: The article is too long to post in its entirety. It is good reading though. http://soldiersystems.net/2015/09/30/something-is-amiss-at-l3-warrior-systems-eotech/ I heard about the temperature shift issues when working with some regional FBI SWAT dudes a while ago. They told me that some guns were tested at Quantico and the change in POA/POI was significant. I was also told that the FBI is now issuing Aimpoint H-1's. It's not like these issues were a super secret that nobody talked about. It's more that nobody cared. NSW and USSOF used them and killed more people than cancer with EOTechs on their rifles. When the issues were brought up them, the response from that community was often - "the reticle is faster for me" or "they make it in FDE". Okay, got your priorities. Then again, the individual shooters weren't paying for it, their units had a huge equipment logistics supply for spare optics, batteries, armorers, technicians, and they had a special relationship with the manufacturer that got them preferential treatment when it came to repairs and replacements - again, all on Uncle Sam's dime. Of course after reading this maybe all those folks who told us that they use EOTechs because "that's what operators use" may feel a little different today. Maybe they will realize that the Aimpoint folks were not lying to them. But probably not.....

Oh, and I found those slugs Vlad recommended. 80 for $77 in a plastic ammo can. http://www.sportsmansguide.com/product/index/80-rounds-fiocchi-12-gauge-low-recoil-2-3-4-7-8-oz-aero-rifled-slug-shotgun-ammo?a=1316451 They were much easier to shoot than the Remington 1oz slugs I started the day with. Especially on stages where you can't get a great stock position due to barricades or positional shooting.

So, that was fun! It was very different than anything I have ever done before. It required a totally new mindset from anything I have been trained to do over the last 13 years. A few times I had to really slow down and fight my instincts on what to do next to avoid a procedural or safety violation. I really enjoyed the rifle and pistol portions. The shotgun portions were challenging. I don't shoot shotgun enough and I am s... l... o... w... feeding the puppy. I knew that coming in, but it was still eye opening. We had a great squad, all were helpful, and I learned a lot from watching everyone. Having Poppa Vlad go first was nice for us newbs and he laid some good wisdom down on us a few times covering strategy, gear and ammo selection, manipulations, and planning your run through the stages. This isn't something I can do often, but I would love to shoot a couple of these matches a year. Thanks again to everyone in squad 2 for making my first 3 gun a fun and challenging experience.

The only difference is for the extractor spring in the LCI Kit.

If it's a police gun it is carried often and shot little. Gun probably has less than 3k rounds through it. If it makes you feel better, change the recoil spring and get new mag springs. If you want to you can convert it to the LCI extractor with a new LCI extractor, extractor plunger, extractor spring, and spring bearing. But none of that is likely necessary. Bring it to the range and blow through 500 rounds of ball and a couple hundred rounds of whatever self defense ammo you prefer. If it doesn't choke, you are set.

Me too. I can't get my QC10 LRBHO to work for shit and it is aggravating as hell....

Getting excited! Got the 870 out today and gave it a once over. Do we need slings on the long guns? Any last minute advice, news, recommendations, etc... ?

Ok, I am in. Somebody talk to me about divisions. I have an AR with RDS, pistol and pump gauge with iron sights. I am shooting factory/duty ammo out of the AR and Pistol. I have a mix of #6 - #8 game loads for the gauge and about 25 slugs. What else is there?
