Step 1: Buy Retaliator

Step 2: Ignore my previous plan to acquire Longstrike barrel, and maybe still get the Stampede bipod.

Step 3: STILL A SNIPA RIFO, since the Retaliator's barrel extension is rifled and the Longstrike's is not. It's less hassle than buying an extra barrel, and there's a chance it may actually help the dart's accuracy. Also replace Retaliator stock with Raider stock (I already have one) because while the Retaliator stock looks better, it's very short.

Step 4 (optional): Go back to the original plan, because even if it may not be as effective it still looks pretty boss.
