yeah it would be really nice to have a AR in .300 whisper but like you said deep end of reloading and way deeper then my pockets go... maybe once i retire and get setup for reloading.

I have the itch for a big bore AR and dont want a AR10. looks like I might just have to jump for a beowulf... or start reloading, go learn gunsmithing, and develop a wildcat... since i can get a ton of free 5.56 and 7.62 nato brass thats not sounding so bad lol

Since this thread was right up my alley (I was looking into a 7.62x39mm upper) I checked it out. Thanks JD for already taking me off that path.

Here's an even bigger question: If I had $500 for an AK, would it just be better (for SHTF) to instead spend that money on more 5.56x45 ammo and magazines for the AR I already have? I can really only carry one rifle when the zombie hordes are coming down my street.

At what point would someone want to move into another caliber upper for their AR-15 caliber? What needs would be better met by a larger caliber upper rather than more ammo and accessories for their current AR-15 in 5.56?

I built one just because I wanted a bit more "thump" at a reasonable ammo cost and more accuracy than an AK can give.

I ordered a flat top kit from Model 1 Sales and picked up a $59 receiver on Gunbroker ($89 after shipping and transfer) about $630 and mags for $18ea I did it opn the cheap just to see if I was going to like it ... used spare plastic magpul trigger guard, set of handguards and a stock that were in my spare parts bin instead of the cheapies that came with the kit.

Originally it was a flat-top because I already had a carry handle. I couldn't get a sight post tall enough to sight it in with irons ... I found a post at DPMS that was .40" taller but still not enough so I switched out the upper receiver for a fixed carry handle upper because the aperture sits about 3/32" lower ... haven't gotten out to shoot it since but am sure that will cure the problem.

BTW - I've shot about 200 rounds of Wolf with no problems (for whatever thats worth )

Sorry guys (JD) but I’m going to have to disagree on the 7.62 in the AR platform on its accuracy. I’ve built two so far for a really good friend and both are extremely accurate at over 200 meters. Now, I will say that I have not measured the targets to get “how” accurate down to the ¼ inch but I will say they we can consistently hit a 10 inch steel plate at 265 meters with iron sights. I am building Glass’s Pink AR in 7.62 because she loved shooting the two I built. I’ll let y’all decide in June at the M&G as I’ll have a couple of them for y’all to test yourself.

KimberKid is that a DI or a GP upper. just curious i thought the laquer'd wolf would foul it up after alot of shooting.

Dzscubie im very interested in how this turns out. please give me a update on it.

it does seem to me that true AR fans have some Hate toward the 7.62x39 round. cant be all that bad of a round and i mean sure ak's arent ment to shoot sub moa at 300yards but that doesnt mean that the round wont do it in the right gun...

Can't say anything about the 7.62x39 in the AR platform, haven't even ever shot a 5.56 AR, but during my military service we got to shoot our issued Sako RK62s to 275 yds(300m) a few times. I'm not a great shooter, but I could still hit a torso sized target easily with the iron sights every time. A good shooter can definitely get pretty impressing results with the 7.62x39 even to 300 yds with the right gun.

Just my 2 cents.

Scubie I think I should probably caveat the following statement with the fact that I like you.

When I say that the 7.62 x 39mm, even on an AR platform isn't accurate, I am stating that position from my belief what I consider "accurate".

A bullet in this caliber will drop only 3 inches from zero to 100 yards, but from 100 to 200 it will drop an addiitonal 12 inches and from 200 to 300, it will drop another 21 inches. That is a 35 inch drop from zero to 300 yards.

Here are some numbers on the 7.62x39 with a 123 grainer:

2400fps at muzzle / point blank zero

50 yds - 2266 fps velocity - 0.80 in bullet drop
100 yds - 2137 fps velocity - 3.30 in bullet drop
150 yds - 2011 fps velocity - 7.65 in bullet drop
175 yds - 1950 fps velocity - 10.65 in bullet drop
200 yds - 1890 fps velocity - 14.20 in bullet drop
225 yds - 1831 fps velocity - 18.30 in bullet drop
250 yds - 1774 fps velocity - 23.25 in bullet drop
275 yds - 1718 fps velocity - 28.70 in bullet drop
300 yds - 1664 fps velocity - 35.00 in bullet drop


The round can easily hit a target at 300 yards, as evidenced by your buddies rifles'. The problem is, your change of zero, in battle field conditions, for a target is going to be VERY sporatic.

You zero at 100 and you have to make up 32 inches of drop, not to mention wind drift, on the fly in the moment it takes your target to get between hard cover points to hit at 300.

If you zero at 250 or 300, you have a moonshot of a trajectory, so closer shots have you aiming WAY low with "Kentucky Windage" to strike home.

I need to clarify my thoughts more often instead of "talking shop". In the shop, we have a preset level of defined characteristics.

ANY round can be accurate. Every round can hit a target it was designed and built to hit. That is why you have videos of guys shooting 200 and 300 yards on YouTube with their pistols and "proving" how accurate they are.

You can take a .22 Magnum and design a platform to shoot dimes at 300 or even 600 yards with the proper application of want and know how.

That doesn't mean a .22 Magnum is an idle 600 yard round.
