Whoever posted about the HK-93, I've seen Century Arms versions of that, not held them. Read some pretty bad reviews about the roller system needing to be replaced right out of the box. I imagine Vector Arms' quality is much better about that. How is the accuracy on your HK-93?
First off, Do not buy a century arms hk93 clone.
I have owned a vector arms hk93 clone, and i currently own a real hk93. Mine is quite accurate. It is a bit heavier than most ar15s out there. They were very rugged and reliable, and built to last. The only real problems i have are the mag prices, and the fact that mine ding up brass. The vector arms hk93 is good quality, but if you can find a good used hk93 that is even better. The trigger isn't the best, but it will do what it is designed for. And they look cool, and not everybody has one like they do with ar15s. If you like the hk93s try and find a real H&K hk93 used at a decent price, you might have to do some looking around, but you will eventually find it. They are built to last so used ones ar still pretty nice. The nice thing about the real H&K hk93s is they go up in value if you take good care of it, which is nice if you decide you want a different gun. I sold my vector arms hk93 a few years back, and one of my friends was looking to get rid of his H&K hk93, so i bought it for $1300. So if you can afford it go for the hk. but if not go for the vector arms. Also, did you check out the wood stock and handguard for the ar15, personally i prefer my bushmaster to my hk93.
And if you plan to reload don't get a mini 14 and test fire an hk93 or clone before you buy it, because some hk93s ding up brass, and some don't. The mini 14 will ding up your brass, and throw it so far away... If you are hit with a shell ejected from a mini 14 it actually hurts.
