{"title":"Tube extensions for Winchester","description":"\u003cp\u003eThe Winchester SX4 and SXP accept tube extensions that increase magazine capacity. On a competition shotgun, capacity before the first reload directly affects how you plan and run stages: more rounds in the tube means more targets before an interruption, fewer moments where your load planning has to account for reloading mid-sequence. For 3-Gun and IPSC Shotgun use, this is one of the most direct modifications available.\u003c\/p\u003e\n\u003cp\u003eThe SX4 and SXP have different thread specifications and are not cross-compatible. The number of rounds added depends on extension length and shell length — always confirm on the individual product page before ordering.\u003c\/p\u003e","products":[{"product_id":"winchester-sxp-tube-extension-ga-12-2-rounds","title":"Winchester SXP tube extension [Ga.12] | +2 rounds","description":"\u003cp\u003eMagazine tube extension for Winchester SXP.
