I liked my 5.56x45 pistol so much that I bought a 5.56x45 factory SBR. Then I found a great deal on a 7.62x39 factory SBR. They're both waiting on the ATF's approval at my local gun dealer. Meanwhile I jumped on the Classic deal for a 7.62x39 for $1000. My only real complaint, if you want to call it one, is that the handguards are way too beefy. I'd prefer a much thinner profile. I can't really bring myself to get a 308Win because the barrel at 16" is too short and it doesn't hold the bolt back on an empty magazine. I can deal with that in 7.62x39 because it's the price you pay for regular AK magazine compatibility, can't understand why they didn't include a bolt lock back on the 308Win models when the same magazines used in AR10's will activate one.
