(1) Sights: AK Notch-n-post vs AR Ghost Ring – I just don’t get the ghost-ring thing.
it's really an apeture rear sight found on the back of the ar. the apeture is generally awknkowledged to deliver greater accuracy...and it does for me. the notch is considered faster at establishing a sight picture and that also holds true for me.
In his Urban Carbine, Jim Crews writes that you must “trust the ring” by just focusing on the front post while the eye will subconsciously align with the ring. When I do this, shots go all over the place. I must consciously align the ring and post for any degree of accuracy, which given how wide the ring is allows for a lot of error. Am I missing something?
use of a smaller apeture increases both accuracy and the time to aquire the target. light transmission is also to be considered.
I do have a red-dot (EOTech) for the AR which makes things a lot easier…..kinda too easy. The purist in me says I should be able to use the irons to a reasonable degree without an outright dependence on the optics. I am really looking forward to trying out the more pistol-like sights on the AK, which would seem a lot more inherently precise than a ghost ring (not-to-mention a lot more what I’m used to).
the ak sight is LESS accurate due to a shorter sight radius...yet, it is accurate 'enough' to ruin your enemy's day.
(2) Recoil etc. – 7.62x39 obviously outstrips .223, but although heavier it is also slower and lower pressure. (I’m thinking here of the pistol analogy of .45 vs 10mm – I hate high-pressure rounds.) So will I get more of a “thunk” than a “crack”?
per clint eastwood in "heartbreak ridge"..."that is the ak47...the preferred weapon of your enemy. i t makes a dinstinctive sound when fired at you!"
the kalashnikov has a lower, throatier boom to it. a 10.5/5/5 ar comes close.
5.56 x 45 is not a high pressure round, per se. it is a high velocity round. due to its' external ballistics, it is easier to shoot than 7.62 x 39...and probably a factor in why the russians adopted 5.45 x 39 in 1974.
Also in their typical respective configurations, isn’t the AK heavier than the AR and better able to absorb kick?
no. an akm is not that much heavier than a 16" ar. the felt recoil is noticeably higher on an akm. a milled ak47 is noticebly heavier than an ar, yet still has a higher felt recoil.
(3) Trigger – The AK’s I’ve looked at have a long and rolling, almost double-action pull compared to the AR’s fairly crisp single-action. Any sacrifice here for rapid follow-up shots, double-taps, etc.?
if a good trigger is what you desire, toss in a red star arms fire control group...a trigger so sweet you'll throw rocks at your ar.
(4) Furniture – The AK includes at-least the option for old-fashioned wood rather than modern synthetic. Other than the obvious differences in durability, are there any other functional considerations? How about weight?
the ak gets warmer. the heat sheilding is not as efficient as the ar.
