No, the stock on the ATI Alpha Maxx Pistol 5.56 - 7.5" Barrel is not adjustable. While it may appear similar to an adjustable stock, it is actually a fixed, blade-style brace designed for stability and control. The brace is manually adjusted by loosening screws, positioning it, and then tightening them. However, the buffer tube itself is not adjustable.

Good evening to you!! The brace is adjustable by loosing two set screw. Hope this helps, have a good rest of your day.

Hi Jorge and welcome. The brace is adjustable (with two set screws) which must be loosened whenever you need to change the length of pull. Details here: https://veriforcetactical.com/product/ar-15-arm-brace-blade-clamp-style-for-round-pistol-buffer-tube/ ---------------- cheers and stay safe!

Hi Jorge, the brace is not adjustable (except by loosening screws)
You can change the buffer tube to a slotted one and add adjustable brace.
