Well I've been running my DTW for a couple of games now and I've been fairly impressed with it, My vanaras mags don't fit it but my systema ones do so all is well. QC wise, other than a somewhat loose mag catch (simple to tighten) ive had no issues yet. As for its hop, my one isn't having any issues. It's perfectly happy with throwing 0.28s out to 55m consistently. In comparison with my PTW, its not as crisp a response but is roughyl equal power (DTW is 314 with 0.2 whilst PTW is 322 with 0.2) both have roughly equal range For the price I payed, I can't fault it
