Barnett Quad 400 Crossbow

The Quad 400 is built around four parallel limbs instead of the usual two, paired with CNC-machined cams and an Anti-Vibration Isolation foot stirrup that Barnett marketed as cutting vibration and noise by roughly 30 percent at the shot. That build is rated at 345 FPS from a 150-lb draw and a 15.5-inch power stroke, for 112 ft-lbs of kinetic energy. The trigger is a Metal Injection Molding (MIM) build with a 3.5-lb pull and an Anti Dry Fire (ADF) safety that blocks the shot unless a bolt is loaded and seated correctly.

The stock pairs a high-density, gas-assist composite shell - unusual enough at launch that Barnett called it an industry first - with a thumbhole grip for a steadier hold at full draw. Period press coverage disagrees slightly on overall dimensions - length runs 37 to 37.75 inches and width 26.75 to 29 inches depending on the source - which is typical for specs assembled from early-2010s release material rather than a single current listing.

The original retail package included a side-mount quiver loaded with three carbon arrows and a choice of sight - either a 4x32 multi-reticle scope or Barnett's Premium Red Dot, depending on the bundle. Barnett named the factory string and cable set on this model CROSSWIRE, its own proprietary term for the strings and cables rather than a separate bolt standard - the bolt family that matters for buying arrows is still Headhunter, confirmed independently by the string length below.

There is no Hyper in the Quad 400's name, so it takes standard-diameter Headhunter bolts, not the narrow Hyperflite shaft. The 39.625-inch string length is the independent confirmation - aftermarket makers cut a dedicated Quad 400 string at that exact length, and a shorter, narrower-diameter string listing would mean a Hyper-series bow instead.

The Quad 400 ships with a rope-cocking device, but Barnett built the stock to also accept a crank cocking device installed under the contoured cheek pieces as an optional add-on - rated at only 16 lbs of cranking effort, well under the bow's 150-lb draw. That makes it one of the easier older Barnett models to retrofit with a crank if the rope cocker gets harder to manage over time.

The Quad 400 is not part of Barnett's current lineup, and there is no new crossbow listing for it - only the 39.625-inch string and cable set turns up as a live product today. Headhunter bolts in 5- and 12-packs fit it, and rail and string lube wax are still sold for any Barnett.

Before buying secondhand, check the limbs, cams and rail the same way you would on any older Barnett - those structural parts are not made aftermarket once stock runs out. If the bow checks out, budget for a rope cocker or crank and re-zero the scope at 20 yards before the first hunt - see the sighting-in guide.
