Overall length of the pistol with moderator on is 19 inches...The barrel length with moderator on is about 15 3/4 and without moderator the barrel is just under 10 inches so if these are the proper rules I got off the
AAFTA Handbook -- Official AAFTA Rules (Last Updated 21 November 2021) then it appears you would be good to go without moderator on. Now I have been wrong before, but I hope this helps.

2. Muzzle energy limited to 12 foot-pounds.
3. Barrel length is limited to 15 inches including any attachments to the muzzle (e.g. moderator, or flip compensator). A wooden or other barrel-friendly dowel will be used to determine the length of the barrel, as measured from the tip of the barrel or muzzle attachment to the breech-face.
4. Fore end depth is limited to a maximum of 3 inches, measured from the center of the barrel to the lowest part of the gun forward of the trigger guard.
5. Attached cylinders at the rear of the Pistol are not allowed.
6. Overall length including any attachments must not exceed 25 inches.

8. No shooting sticks or mono/bi/tripods.
9. Kneepads may not exceed 1 inch in thickness. The intent is to allow comfort, and not an extra form of support.
