![]() As a result of the lengthened powerstroke, the bow’s speed is increased tremendously. This simple, yet ingenious way of mounting the cams on the bow elongates the powerstroke by about 4 inches-or the width of the cams-by merely flipping them over. Two giant “inverted” cams are oriented upside down so the string is further from the fire control system. This is a testament to the XXTreme’s overall solidness. The CenterFire XXTreme registered around a 93 on my informal sound meter while shooting outside, which is right up there with the best I’ve ever tested. All told, it’s as solid as risers come these days, and no doubt a big reason why the bow is so quiet. Behind the limbs, two sound dampeners accept the string’s excess energy and dissipate sound waves that would otherwise lead to excess noise. Its limb pockets are serious pieces of metal that anchor the limb ends and serve as a pivot point to provide a fulcrum for leverage. That’s because the XXTreme’s riser, which is about 13/16th inches wide at its thickest, provides an anchor-like platform for attaching the CenterFire’s laminated split limbs. The XXTreme is no exception, and you can see that in its performance-namely its quietness and accuracy. Parker is willing to add a few ounces to its overall weight in exchange for such a riser. Parker is known for its beefy, machined risers that provide a solid foundation for the entire bow, including its limbs and limb pockets, barrel and eccentrics. You’d be hard pressed to find a better crossbow for the money. Parker is committed to building no-gimmick, solid crossbows that shoot supremely accurately, and are extremely quiet, safe, powerful and inexpensive. It’s rather compact at 20.75-inches axle-to-axle un-cocked and 18.5-inches cocked with a 13½ inch length of pull. ![]() It’s a 170-pound draw weight crossbow that’s 34.25-inches long, 7.6 pounds in overall weight (with the scope) and fires an arrow at 350 fps thanks to aggressive cams and a 14.125-inch powerstroke.

Rare is the instance that a crossbow can withstand a dry-fire without some type of damage. If any problems are detected during the entire inspection process, take the crossbow to your local pro shop or contact the manufacturer immediately. If nothing has been detected again visually inspect the entire crossbow and perform the cotton ball test on the limbs one more time. If no damage has been found to this point, slowly cock the crossbow listening for any unusual sounds. If any limb flaws are encountered they will pull small fibers from the cotton ball and be revealed immediately. If none are noted, rub a cotton ball over the complete surface and edges of the limbs. Visually inspect the limbs for splinters, cracks or chips. Next a complete limb inspection should be performed. Gently run your fingers along each asserting a moderate amount of pressure to make certain that there is still tension on the string and that no strands have been damaged. If everything looks to be intact, the next step is to inspect the strings and cables. If it’s a compound model, visually inspect the cams thoroughly ensuring that no damage has occurred and that the string and cables are still slotted properly. If it is a recurve-type bow make sure that the string loops are still securely slotted on the limb tips. The first thing that you want to inspect is the limb tips or cams depending upon your model. ![]() ![]() You MUST assume that damage has occurred. If you have experienced a dry-fire, it’s imperative that the crossbow be immediately and thoroughly inspected before it is shot again. If you have a dry-fire, you must thoroughly inspect the crossbow before it is shot again. However, there are certain precautions one must take after a dry-fire regardless of the type of crossbow. This is due largely in part to their simplistic design and their lack of cams and cables. Recurve crossbows are much more prone to survive a dry-fire with little to no damage than their compound counterparts. Either way the resulting damage to the crossbow can range from catastrophic to minor. Most people think that they’ll never dry-fire a crossbow, but if you spend enough time shooting one it will probably happen.Ī dry-fire can be as blatantly obvious as having forgotten to load an arrow onto the bow, or as subtle as having a nock failure, which can cause the string to go over or under the arrow.
