Hi Justin, the TaurusTX 22 pistol comes with a suppressor adapter collar so that it can be used with a suppressor. The suppressor adapter collar features an external thread of 1/2-28 which is compatible with the majority of .22LR suppressors available on the market.
Stay safe & have a great day!

Okay. I stand corrected. Bud's has a poor description in the listing. The barrel is threaded.
