The inserts are black on every kit, which gives the colored windows some nice contrast. Once it's put together, the barrel measures 14.5\" from end to end.\u003c\/p\u003e\n\u003ch2\u003eHex Windows With Something To Show Off\u003c\/h2\u003e\n\u003cp\u003eBoth the back and tip are machined from high-grade aluminum with HK Army's Hex windowing and fractal detailing. Those cutouts aren't just for looks. They give you a view of the spiral fluted insert inside, so the finished barrel has a lot more going on than a plain tube.\u003c\/p\u003e\n\u003ch2\u003eEight Inserts So You Can Match Your Paint\u003c\/h2\u003e\n\u003cp\u003eEvery Vector PWR insert is micro-honed for a smooth, consistent bore, and the size is laser-engraved so you always know which one is in. Check your paint with the included ball sizer, drop in the insert that fits, and you're ready to play. The breech end is chamfered to help cut down on ball clipping, and the alignment interface keeps the insert locked where it belongs.\u003c\/p\u003e\n\u003ch2\u003eQuieter Shots And Tighter Groups\u003c\/h2\u003e\n\u003cp\u003eThe control bore setup keeps velocities steady from shot to shot, and the tuned porting on the Hex PWR tip helps tighten up your groups while bringing the sound down. You'll notice it when you're trying to stay quiet on a bunker or just want every ball going where you aim it.\u003c\/p\u003e\n\u003ch2\u003eWill It Fit My Marker?\u003c\/h2\u003e\n\u003cp\u003eThe barrel back uses Autococker threads, which is the most common thread on paintball markers today. HK Army also lists it as compatible with Planet Eclipse PWR-equipped markers like the LV2, CS3, CS3 Pro, and GTEK 180R.
