VFC OEM NPAS Nozzle V2 for VFC M4 V3 GBBR, Black

A worn nozzle is how a GBB rifle starts losing its edge. The seal degrades, gas efficiency drops, and your shot-to-shot consistency goes with it. This is the fix: the VFC OEM NPAS Nozzle V2, built to replace the original part in your VFC M4 or AR-15 V3 gas blowback rifle.

What the nozzle actually does. It's the part that seals against the bucking every cycle to compress the air column behind the BB. When that seal wears, velocity drops and shots get erratic. Swap it out, and you get the crisp, repeatable feel back. Think of it as the single most impactful maintenance item for any GBBR.

NPAS means you can tune it. The NPAS (Nozzle Position Adjustment System) lets you change the nozzle's position, which adjusts the seal pressure against the bucking. Tighter seal equals more pressure behind the shot, looser means less. That gives you a rough velocity dial without splitting the gun or swapping springs. Turn it down for indoor fields with tighter caps, turn it up when you're back outdoors. The exact range depends on your BB weight, gas type, and ambient temperature, so chrono your setup after any adjustment and before your first game.

OEM fit, no guesswork. This is VFC's factory nozzle for the M4 and AR-15 V3 gas line — polymer construction, 90mm length. It drops in with factory tolerances, so you're not chasing alignment or stretching the cycling stroke. Your blowback action, bolt lock, and recoil rhythm stay exactly like they were from the start.

When to grab one. If your rifle's cycling feels sluggish, gas consumption has crept up, or your chronograph readings are starting to wander, the nozzle is usually the first thing to check. For players who run their GBBR frequently, replacing the nozzle alongside a bucking swap is the standard refresh that brings the whole air system back to life.

Compatibility. Designed specifically for VFC M4 and AR-15 series V3 gas blowback rifles. It will not fit non-VFC platforms or AEG gearboxes. Check your model before ordering.

Ships as a single nozzle. A small hex key or adjustment tool may be needed for the NPAS tuning — your rifle's existing tools should work.
