Yep. After US Palm first released their AK30 mag, K-Var dropped the price of Circle 10s from $43 to $35. However when reports started coming in about AK30 mags cracking feed lips, and the "non-removable" floor plates began launching into low earth orbit, the price of Circle 10s was raised to $40.
If these and Magpul's reinforced AK Pmags pan out, I imagine K-Var will again drop their prices competitively.
