Helpful Negative Review
Damaged upper with wrong parts by Tyler Moody, Verified Owner, November 26, 2021
I just received the 18" stainless steel upper that was supposed to have a Tacstar carbon fiber handguard but it only has an aluminum handguard and the whole thing is covered in scratches and dings. Complete ripoff.
