AIR SEAL NOZZLE FOR M4 21,4MM [POINT]

Great quality air seal nozzle. It fits perfectly in my M4 and provided a noticeable boost in FPS consistency due to the excellent seal. Very durable material.

The AIR SEAL NOZZLE FOR M4 21.4 mm by POINT is a small but important internal upgrade part designed to improve the air efficiency of M4 AEG replicas. Made from CNC-machined aluminium, it is noticeably more durable than standard plastic nozzles and includes an O-ring that helps create a tighter seal between the cylinder head and the hop-up unit. This improved sealing can lead to better FPS consistency and slightly increased overall performance.

In practical use, the nozzle is lightweight (around 5 g) and precisely sized at 21.4 mm, which is a common specification for M4 platforms. Installation is relatively straightforward for users familiar with gearbox work, and once properly fitted, it generally operates smoothly without affecting feeding. However, compatibility can vary depending on the exact replica, and in some builds the O-ring may feel tight or require adjustment.

Overall, this POINT air seal nozzle is a budget-friendly yet effective upgrade for players looking to improve compression and consistency in their M4 AEG setup, especially when replacing worn stock parts.

The Point Air Seal Nozzle is a CNC-machined aluminum upgrade with an O-ring for better air seal and FPS consistency. Works perfectly with the CYMA CM.515, offering improved durability over stock plastic nozzles. Just check O-ring fit, as it can be tight on some cylinder heads. And pay attention not every replica using this type of nozzle. For example it not compatible with Specna Arms nozzle.

This air nozzle is ment for an M4 replica. It is nicely machined and polished. However, there is one problem. The O-ring is too thick. And therefor it does not fit on all of the cylinder heads. You can get it on most of them, but it's very hard to move and you'll get air seal problems (nozzle not moving fast enough to the hop-up rubber). So, you can replace the O-ring (not fun to do) or find a propper cylinder head.

Got as a replacement for vfc m27. Since I put together the gearbox from scratch I had a G&G cylinder head and this nozzle had a perfect seal and slid smoothly during cycling. Couldn't be more satisfying.

A good sealing nozzle for M4 type guns with 21.4mm nozzle lenght.

NOTE: the nozzle is a little bit to big toward the gearbox part. needa some work to properly fit inside most/all hop-up units i used them on.
