The TIA is right now being used for uppers and is not available separately. Usually with PSA once demand dies down we see more options available on the website.
Does anyone know what “TIA” Stands for? Yes I understand it’s a muzzle device on a AR-15. If someone at H&R is reading this, please shed some light on this subject. Things aren’t named without a meaning? Thank you for your attention to this matter. D.J.T.
