Do your self a favor and don't send any more than a 25% deposit.
I've been full-time in the gun business for more than 30 years and the greatest likelyhood of disappointment in that whole time has been ordering a new rifle action from new action makers.
I have no knowledge of this company in particular, (except they have been promising the 223 mini action on AR forum for more than a year) but do note that the action shown is a flat side, octagon top, the least desirable in my opinion, and the barrel contour doesn't look like anything I've even seen before. When J.D Steele has one in hand to evaluate for us it will be safe to think about ordering.
I may get flamed for this... but I've seen, and been disappointed so many times...
And Vol please do keep us posted on any activity, or lack of...thanks!
