It’s the M2010 sniper rifle that makes him a US Army Ranger as the US Army only uses that rifle, according to Wikipedia. @metalhead85
Maciek sells a 120mm M110, but then you have the issue of “Hands aligning with the rifle” if you substitute a different rifle.
Here are Airborne Miniatures’ modern sniper figures in 1/9, 1/16, and 1/35 scale. Maciek does do custom orders if you ask him and pay via PayPal (like asking and paying for extra parts if he has them). I bought from Maciek many times directly and service and shipping were excellent and he’s a trustable seller. The best thing to do is email him directly.
