Damaged and proprietary parts - Spikes Tactical .308 Barrel Kit for AR-10 w/Gas Block & Tube

Received the barrel with the two day shipping promo. Barrel was damaged in shipping. It did not have a thread protector on the end. The bag was still sealed so it didn’t fall out, just didn’t have one. Had to hand file the threads a bit to get my muzzle device to thread onto the barrel. The proprietary gas length did not seem like a big deal to me, but that may not be the case. I am having issues with cycling, as in not reliably cycling. I also wish to shoot suppressed, and would like to install an adjustable gas block. With the proprietary gas tube length this limits available options.
