I found Reg on eBay before I got hammer, and I got another one on eBay with a ninja 68 tank for $120. I bought a seal kit also from eBay to have a spare. All 3 regulators are identical. The brand new one came with 3 shims. The hammer came with 2. And the one with bottle, came with 3 shims. The kit came with 3 shims. I haven’t looked for a bottle for the gun, since I can teather it to 68 CU tank , and have about 8 shots on tap. 1 shim it shoots slower but you get 2 extra. 2 shim stock, and 3 shims according to Ninja Manual bumps it up to 3200 psi. Haven’t tried more than 3, and don’t intend to, because it shoots amazing. In its current configuration, I’ve shot over 1k rounds, and still holds air w/o leaks. That’s a 380 gr BT
