@hector_j_medina_g Yup! Says so in the description. .22 only but might be able to mod it to .177. Thank you, you are a Gentleman and a Scholar!
Actually, there is a gen2 that uses a bushing:

to become a 0.177" cal
I've read of people having issues with the bushing coming out in the middle of a match, so if you go for this more expensive one, it might be good to ask what sort of remedies there are.
There is a huge price difference, so it really behooves you to look into it in detail.
Keep well and shoot straight!
