MOST EFFECTIVE: Krinkov 7.62 or AR W/short barrel?

[SharpsDressedMan]

Both the 7.62x39 and the 5.56 lose a lot with the really short barrels. Which would be the better choice for incapacitation with the Krinkov length or 7-8" AR "pistol" length upper in 5.56? I would think the 5.56 had the hydrostatic shock edge in the full length, but when you start curtting velocity drastically, things change. Anyone got any opinions or hard info on this?

I would say that the 7.62 is the more powerful round. Which gun would function more reliably from that short of a barrel would be my main concern.

Without any doubt, the 7.62x39 is far more effective than the 5.56x45 from a short barrel, if that's what you're asking. Reason being twofold - it's heavier and doesn't rely solely on velocity/yawing/fragmenting to do its damage, and secondly, it 'loses less', relatively speaking, going from a "normal" to a short barrel, due to expansion ratio, being a larger caliber.

But better yet, get a .50 Beo in an AR15 platform - better than either.

If it were me I would go with the krink. I believe it would be more reliable. I have no hard info the subject, but just looking at the mechanics of the two actions, the AK's gas piston system would be more reliable in my eyes. Heck, it seems like most guys that are building SBRs are going with gas piston set ups these days anyway to alleviate prior cycling problems common in shortend gas systems in the AR platform.

The krink was designed to operate with a short stroke gas piston and it does just that, and quite fine if I might say so myself. Also, Look at the Draco AK pistols. Again, short barrel, short stroke gas piston operating system that functions flawlessly. I have one and it eats everything I feed it. I have two other friends with Draco's that also function just fine as well. Thats 3 for 3 in favor of the krink/draco short stroke gas system.

Plus the 7.62x39 round will carry more ummph upon target impact as well as making a bigger hole for blood to escape the body quicker, which will result in a quicker death for the victim. Ammo is also ALOT cheaper so you can PRACTICE PRACTICE PRACTICE!

These are just my thoughs and opinions.....

Im sure the AR fans will begin my bashing shortly......

Biggest issue with a short barrel.........NOISE.....put your ear plugs in before you take it off safe! That and muzzle blast. You better be wearing tinted safety glasses at the range. Beachball sized muzzle blast is common. Look into a Noveske flash hider. Theyre supposed to be the cats meow for taming the blast.

It just made me wonder. I've seen the M16 get cut down shorter and shorter, with tactical teams favoring the shorty guns more and more. Seeing as the Krinkov has been around a long time, I just wondered how they compared. It might be a reason to step the shorty AR up to the 6.8 or even the .300 Whisper (my favorite for many reasons). I have seen the 125gr Ballistic tip bullet loaded to 2100fps in the .300 Whisper from a 9-10in barreled AR. This isn't quite 7.62x39 ballistics, but then I've never seen actual ballistics for the Krinkov over a chronograph. Anyone ever do a chrono or ballistic chart for the 5.56 from short barrels?

 

[bkjeffrey]

Ive never seen any chrony or ballistics from a Krink. Heck, Try even finding a krink for sale right now. If you do let me know!
