Tested: PSE RDX 400

PSE continues to forge ahead in the crossbow industry with models that cover a wide range of applications and hunter budgets. It brings to bear numerous years of hunting and manufacturing experience as it focuses on giving loyal consumers what they want in a crossbow. New for 2016 is the RDX 400, which spices up the Reverse Draw platform with smoking rapidly bolt speeds.


PSE’s RDX 400 crossbow generates superb speeds with its reverse-draw dual cams and X-Tech split limbs. The skeletonized stock and foregrip are injection molded and give functions such as the raised comb and the ribbed pistol grip to boost the shooter’s experience. The black anodized aluminum rail serves as the bridge amongst the bow and stock and is also home to the trigger housing. Sitting atop the trigger housing, a Picatinny Rail is ready for PSE’s 3×32 Illuminated scope.

The RDX 400 attributes a skeletonized stock and foregrip, a machined aluminum rail, a set of reverse-draw dual cams, a stout riser, PSE’s patented X-Tech split limbs which are produced from market-standard Gordon Composite and much far more.

The Organization Finish
The RDX 400’s aluminum riser is each compact to match the general footprint and stout to offer the strength and rigidity necessary to help the intense power utilised to create quick bolt speeds. A set of dual RDX Backstop string stops are attached to the inside of the riser and attain out to quit string oscillation at the shot. The interface in between limbs and riser is very vital.

PSE’s complete-manage limb pockets serve to align and position the limbs precisely, permitting the general machine to operate effectively. Established and patented X-Tech limbs are constructed with Gordon Composite material, measure 12.35 inches in length and are split in kind. Each and every of the 4 limbs is outfitted with two vibration-dampening accessories.

PSE makes use of a dual-cam technique to power its reverse-draw mechanism, which is advertised to hit speeds in between 390-400 fps shooting a 400-grain bolt. In a reverse-draw configuration, the string spans the cam’s riser side and when drawn rotates the cams inward rather than the common outward motion. This adds length to the power stroke, and in turn increases speed. A foot stirrup attached to the front finish of the riser aids in manually cocking the 400.

The Bridge
PSE’s independently machined aluminum RDX Barrel rail bridges the gap among the bow and the stock/foregrip. At the front end it involves an open channel that accepts the cables and cable slide, although at the back end it houses the trigger housing and bullpup-style trigger linkage. All along the black anodized barrel are several cutouts to lessen overall mass weight.

The trigger mechanism employs Metal Injection Molded (MIM) components and is advertised to create a pull of just three pounds. As the bow is cocked, the trigger safety is automatically engaged and works with the anti-dry fire feature, which will not permit the string to advance with no a bolt loaded, to avert accidents.

A spring steel bolt stabilizer and machined Picatinny scope mounting rail are attached to the best of the trigger housing.

Hunter Interface
The RDX 400’s 1-piece stock/foregrip unit serves as the interface among shooter and crossbow. With that in mind, PSE equipped it with a ribbed butt plate, a raised comb with soft plastic overlay for comfort and fast target acquisition, molded finger indents on the front of the pistol grip, an oversized trigger guard for gloved fingers and a pass-thru foregrip for added handle and security. Other than where it meets the rail, this integrated unit is notably skeletonized to maintain mass weight to a minimum. The stock, riser and limbs are accessible in either black or Mossy Oak Break-Up Nation.

Included accessories are: a PSE 3×32 Illuminated XO Crossbow Scope, PSE Speed Loader, 5-Bolt Quiver, three Charger carbon bolts, 3 85-grain Bullet points, sling, cocking rope and rail lube.

At the Range
The RDX 400 lived up to expectations, clocking in on our chronograph at 375 fps with a 420-grain bolt. If you’re able bodied, the integrated rope cocker is the quickest choice with a fairly simple draw. Nonetheless, if you’re injured or just want an less difficult cocking expertise, the PSE Speed Loader is easy to master.

The test bow needed a considerable quantity of force to seat the bolt deep enough to move the anti-dry fire mechanism out of the way. Target acquisition was rapid with the XO Scope, which was bright and clear.
