The General AR Discussion Thread

I'm going to advertise a 2000 323i for sale. I'm expecting to get about $15k out of it.

I'll also accept two loaded pmags in trade.

Ill take you up on that. I'll even be generous, 4 PMags..

Rofl. Selling 1000 rounds for 1000$. Vendors are insane!!! Cheapest pmag was 35. Most were 50$.

I left with a new eotech and a few other small goodies. Nothing major though.

Pricing is getting ridiculous. I'm considering a pistol just for range fun until prices drop on rifle ammo

Now seems like a great time for one of those .22lr drop in kits. Can still shoot and I get to keep up my stock 5.56/.223

That's pretty much what you did say. I just had to complicate the matter.

More of a by-product of the fear and paranoia, I suspect. However, the ammo consumption has been high since the election, which is what happened in 2008. I couldn't get affordable bulk ammo until about April or May of 2009.

I would say that carbine length gas systems are more utilitarian and adaptable. This allows them to be more tolerant of the extremes overall when it comes to ammunition. The carbine gas system has been around a lot longer, so there's been a lot of development with it. In contrast, the midlength is just getting out of metaphorical puberty. Good companies like BCM, DD, Noveske, etc. are able to develop reliable midlength systems because they have done the R&D. Midlength systems are more reliable with the higher pressure milspec ammo, and they're more durable because the softer recoil and lower backpressure doesn't beat up the guns as bad. The problem is that there are companies that don't do very good R&D-or do none at all- and they can screw it up. Carbine systems are pretty standardized, so for companies that don't have higher QC standards or better resources, the carbine system is the more reliable platform for them. I think the carbine system is harder to jack up, but that's just my conjecture.

I found Federal American Eagle AR .223 rounds today. Bought a box of 100 only because I haven't even been able to shoot my AR, let alone test fire to make sure it's worth buying a case of 500 rounds.

Hopefully I'll be able to go shooting tomorrow... I'm deer hunting in the morning, we'll dare see if I try shooting some paper during lunch.

So happy, got a PSA PA-15 for Xmas and went down to the local accessory department aka "my dads safe" and hooked it up with a new blackhawk handguard, EOTech sight, and bipod. Put a couple of mags through it at the range on Thursday and am incredibly impressed. Not a single jam compared to the Bushmaster we were also using, jamming on about 4-5 rounds. Damn thing also came with a 30 round mag, nice bonus.

Also, just got home from the Chantilly gun show today in VA and picked up a nice Class IV Kevlar Body armor unit. Nice Xmas.

New to the AR system, does anyone have any recommendations for a scope w/ a rail to mount the EOTech on top of? I'm looking to keep the EOTech but want something more than just sticking a magnifier behind it. I was looking around at the show but couldn't really find anything I liked, due to the chaos of thousands of people there. Or is it the standard to just put a magnifier behind it and if so, pointers?

How was the gun show? Any reasonable prices?

FINALLY got my LOWER!!

American Eagle ammo is good quality. You can buy that and be sure it'll function well.

If you get a good PSA, they're decent rifles. A number of their parts come from FN and LW Scneider (not the Grade 1 stuff).
Just keep it lubed with some quality synthetic lubricant like Slip2000 EWL or FrogLube, and all will run smooth.

Do you mean Level IV plate armor? If so, please answer these questions if you get a chance:
Are the plates ceramic?
If not, what are they made of?
If they are ceramic, are they used or new?
Do you have any paperwork that was provided with it?
What company made them?
If they are used, do you have any documentation of recent x-rays of the plates?

If there are no hard plates, it can only be Level IIIA at highest rating.
If you didn't mean Level IV, what did you mean?

This is going to be long, so go run to the bathroom quick before reading this...

If you mount a scope on an AR, and then mount an EOTech on top of the scope, which is what it sounds like you want to do, you will have an EOTech at approximately 5-6" height over bore (HOB). This is a VERY bad idea. There are a couple picatinny ring mounts available from Badger Ordnance and a couple other companies like SPUHR and whatnot. However, they are designed for laser target designators, night vision attachments, or else mini red dot sights (MRDS) like the Trijicon RMR or Leupold DeltaPoint.

You are creating three major issues by doing this:
1. You will not be able to get a cheek weld when using the EO. It will be too high. This will affect accuracy.

2. With an HOB that high, you will have significant issues with zeroing the EO. If you did this setup, you would need to zero the EO at the same range as the scope for reasons of continuity and efficiency. This would likely be a 100yd zero as the best option. The problem is that your scope HOB will be between 2.250" and 2.750" over the boreline (reticle is in center of tube), depending on the mount or rings you use. The EOTech would be somewhere around 3-4" above that, which would create a much steeper angle of adjustment. This would affect long range hold-overs, and the hold-overs would differ between optics for any range from 0-50yds, and again after about 125-150yds when the bullet is climbing to or dropping down from the maximum ordinate (highest point in the trajectory). Again, not ideal.

3. This would throw the balance of your rifle off tremendously. That much mass that high up would make your rifle top heavy. This will hamper everything from movement with the rifle to transitioning between targets while shooting. This is not to mention that EOTechs are not all that light, and when you spend enough time shooting, ounces equal pounds, and pounds equal pain.


Beyond that, and really going to the root of the issue, I think you are trying to make the rifle fit into too many categories. It's akin to taking a BMW 3er and putting racing slicks on it, and then giving it a 12" suspension lift so that you can race people, but then go offroad when you need to. It's just asking too much out of the rifle's setup.
Now, if you were to switch to a scope with a firedot or flashdot like the Leupold Mark6 1-6x or Mark8 CQBSS 1.1-8x, S&B PMII 1-8x Shortdot, Swarovski Z6i 1-6x, Trijicon AccuPoint 1-4x, etc etc, it'd be a different story. Those have a 1x bottom end with a reticle that is brightly illuminated for use like a red dot, but magnification for use for long range shots. Going back to my previous BMW analogy, this method is like buying an X5M. You get a vehicle that can race, but you can drive off-road a little bit if need be. You have a more integrated and purpose-built setup.

If you decide that you want a scope, and still want an exterior red dot, there are better ways to go about doing it.
There is the offset mount style, like this:
http://www.ar15armory.com/forums/lof...p?t121035.html

Or a 1 o'clock rail mount option, like shown here:
http://www.ar15.com/archive/topic.ht...&f=18&t=469630

Red dots that are offset mounted like above are designed to be emergency CQB sights as a supplement to weapons whose primary purpose is midrange to long range DMR employment. They're not meant to be run as a primary optical sighting system. Not only that, but they're not for people who are novices or people who don't have a lot of the fundamentals of running a carbine locked in. It's an advanced system that requires extensive training to be able to run efficiently. This is not an easy sighting system to run.
Take notice though, that these systems were designed for compact, lightweight sights like the Aimpoint T1/H1, Trijicon RMR or Leupold DeltaPoint. They weren't designed for heavy, bulky EOTechs.

Instead of this, consider getting LaRue or ADM quick-detach mounts for the EOTech and the scope, and you can take them on and off at will with no loss of zero.

OR, invest in a scope designed to fill this role, like those listed above with a 1x bottom magnification.

I just picked up a second lower... All they had left was S&W. Im going to make something lightweight like this with FDE furnature:



Here is my left handed Stag



Also wishing I wouldnt have sold my AR10 build last year

S&W M&P15s are good quality. You could do a LOT worse than a S&W lower.

Yeah, the S&W is quality. Where the heck did you find one? Or did you have to pay out the ass for it?

Dont get me wrong, i like s&w... It matches my 442. Got it a turners 10 days ago for $130.
