\u0026amp; Precision\u003c\/b\u003e: CNC machined from 6061 aluminum, crafted from a solid aircraft-grade block with tight tolerances to maximize accuracy and durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHPA \u0026amp; M4\/M16 Compatibility\u003c\/b\u003e: Specifically engineered to perform with HPA PolarStar engines on standard M4\/M16 platforms and accepts M4 nozzle lengths, while remaining compatible with a wide range of buckings without FPS loss.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFine Hop-Up Control\u003c\/b\u003e: Precision rotary dial knob for micro-adjustments paired with a redesigned hop-up lever and 4mm bucking nubs (6mm bucking nubs optional) to optimize flight stability for both R-Hop and standard-hop configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCentred Inlet Adaptor\u003c\/b\u003e: Interchangeable inlet adaptor OD11mm guarantees exact centering at the 11mm nozzle outlet, with optional OD11.5mm and OD12mm adapters for different setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSturdy Mechanical Support\u003c\/b\u003e: Removable CNC brass side wings slide into outer barrel slots and a CNC Delrin locking C-clip secures the inner barrel without wobble or twist.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBB Latching System\u003c\/b\u003e: Built-in BB latching mechanism prevents BBs from dropping after magazine removal; the arm can be pressed to release remaining BBs for quick reloading.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eUV Tracer Add-On\u003c\/b\u003e: Dual UV LED Tracer Module option lights BBs in the dark for tracing and training (operating voltage 7–15V DC; sold separately).\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWhat’s Included\u003c\/b\u003e: 1 x CNC Aluminum Hopup Chamber M4P Pro (with BB Latching System), 2 x CNC Acrylic Side Covers, 2 x CNC Brass 2.5mm Side Wings, 1 x CNC Steel Pivot Pin, 1 x CNC Aluminum Hopup Lever, 1 x CNC Aluminum Soft Round Nub (4mm), 1 x CNC Aluminum Soft Flat Nub (4mm), 1 x CNC Aluminum Hard Concave Nub (4mm), 3 x Steel Nub Springs, 1 x CNC Steel Spring Guide, 1 x Steel Upper Compression Spring, 1 x Steel Center Compression Spring, 1 x CNC Delrin Locking C-Clip, 1 x CNC Brass Barrel Spacer, 1 x Brass Barrel Spacer Holder, 1 x Oring, 1 x CNC Aluminum Rotary Dial Knob, 1 x CNC Aluminum Inlet Adaptor (OD11mm).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe M4P Pro is designed to translate engine performance into repeatable accuracy. By centering the hop-up chamber with the M4 nozzle and locking the inner barrel, it minimizes wobble and BB misfeeds, delivering consistent shots across the magazine. The fine-tuned rotary dial provides precise hop-up control for different BB weights and environmental conditions, while the optional UV tracer module helps for night games or practice in low light. Built from aircraft-grade aluminum and finished with meticulous CNC craftsmanship, this chamber offers durable reliability for long-term field use. In controlled tests, FPS gains of roughly 10–30 FPS above stock configurations have been observed when tuned properly, depending on nozzle length, bucking type, and other setup variables.\u003c\/p\u003e \u003cbr\u003e \u003ctable border=\"0\" width=\"100%\" cellspacing=\"0\" cellpadding=\"1\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd valign=\"top\" bgcolor=\"#cccccc\"
