CenterPoint Sniper G4D: Specs, String Length and Replacement Parts

The Sniper G4D is one of the two newest de-cocking crossbows in CenterPoint's current range, alongside the Amped G2D. It is unusually compact: 6.75 inches axle to axle cocked and 27.95 inches overall, narrower and shorter than almost anything else the brand has sold. That is the point of the design - it clears tight ground blinds and carries easily on a long walk in. CenterPoint rates it at up to 400 FPS and 142 ft-lbs of kinetic energy, with an 8 lb mass weight before accessories.

The package is complete out of the box: a 4x32 scope with red and green illumination, three 20-inch .003 carbon arrows, a detachable quiver, rail lube and a detachable silent crank with de-cocking. The limbs are compression fiberglass quad limbs on an aluminium riser, and the buttstock adjusts through four positions. An anti-dry-fire mechanism and auto safety are standard, as is the Whisper silencing system. CenterPoint does not publish a draw weight or power stroke for the G4D, so those are left out of the table rather than estimated.

This is the number people come looking for, and it is genuinely hard to find. CenterPoint does not list a string or cable length for the Sniper G4D anywhere, and because the bow is recent, the aftermarket catalogues that normally publish a measured length for older models do not show one for the G4D yet. Custom shops such as 60X and Catfish will build a Sniper G4D string and cable set to order, but they build it to the bow rather than to a published number, so the listing carries the model name, not a length.

That leaves two reliable routes. The first is to order a set listed specifically for the Sniper G4D - read the title carefully, because a search for Sniper strings will surface the Sniper 370 at 37.2 inches and the Sniper Elite 370, which are different bows and will not fit. The second, and the one to trust if your bow has already been restrung once, is to measure the string that is on it, loop to loop under light tension, and order to that figure. The same logic covers every discontinued model on the strings-by-model page: length is the specification that matters, not the badge.

Because the G4D is a compound, the string and the cables wear as a system. If you are restringing a bow that has seen several seasons, order the matching cables at the same time rather than coming back to them inside a year.

The Sniper G4D is set up around a 20-inch .003 carbon arrow - that is what the three bolts in the box are, and it is the length to stay with. Replacements do not have to be a CenterPoint-branded bolt; any quality 20-inch carbon bolt at roughly 400 grains total with a half-moon nock will chamber and fly correctly. The Carbon Express PileDriver 20-inch is the one most CenterPoint owners reach for, and it is the bolt referenced across this site's model pages.

What matters more than the brand is matching three things when you reorder: overall length, total grain weight and nock type. Change the weight and the bow prints somewhere else, so a heavier or lighter bolt means re-sighting. The bolts page covers nock fit and the broadhead-versus-field-point question in full.

The G4D ships with a detachable silent crank, and de-cocking is the feature its D suffix refers to: you can let the bow down at the end of the day without firing a bolt into the ground, which is both safer and cheaper than the old discharge-into-a-target routine. The crank comes off the bow once the string is cocked, so you are not carrying its weight on every shot - the same approach as the AT400, and different from the Sinister 430D, whose crank stays built into the stock.

Because the crank is included, there is no need to buy one separately for this model. If you ever lose or damage it, the cocking-device page explains which CenterPoint cranks fit and when a rope cocker is a reasonable stand-in.

Within the current range the G4D is the compact, carry-anywhere option rather than the fastest. The Sinister 430D is the top of the range at 430 FPS and a 225 lb draw, the Hellion 400 matches the G4D's 400 FPS on a wider, more conventional frame, and the AT400 is the entry-price package. The G4D earns its place on width: if your hunting is from a blind or involves a lot of walking, 6.75 inches cocked is a real advantage the faster bows do not offer.
