KWA KMP9 Gas Blow Back (NS2 System) (Tan) (Railed)
This KWA KMP9 is the railed version of KWA’s compact NS2 gas blowback SMG, finished in tan. The extra rail space means you can add a light, laser or grip without losing the slim, compact profile that makes the KMP9 such a good CQB gun.
KWA is known for strong, reliable gas systems, and the KMP9 family has become a popular compact SMG for players who want real blowback in a light package. The tan finish suits desert, coyote and multicam loadouts.
Build and handling
The KMP9 is built around a fibre-reinforced polymer frame with a steel inner barrel, according to a US retailer, which keeps the weight down while staying stiff and durable. A vertical foregrip is moulded into the front of the frame, so your support hand always has somewhere to go.
The R model adds extra accessory rail space beneath the handguard area, according to the same retailer, so you can fit a light, laser or extra grip alongside the top and side Picatinny rails. The folding stock, with its thumb groove, lets you shoulder the gun for accurate shots and fold it away for storage or very close quarters.
Performance
Every shot drives the bolt back for realistic gas blowback, and the retailer lists both semi-automatic and fully automatic fire with an active trigger safety and a working cocking handle. The hop-up is adjustable, so you can tune the gun to your chosen BB weight.
According to the same listing, the steel inner barrel is 140mm long with a 6.05mm bore, and the muzzle is threaded 14mm CCW. Green gas is listed as the power source, with a 48-round gas magazine.
Getting started
Before your first game, read the manual, fill a magazine with green gas and load it with good quality BBs. Test the gun at a safe backstop and adjust the hop-up gradually until shots run flat, then have it chronographed at your site.
In cold weather gas pressure drops, so carry spare magazines somewhere warm and shoot at a steady pace rather than emptying a magazine in one long burst.

Compatibility
Use magazines made for the KWA KMP9/KMP9R. A US retailer lists a 48-round standard magazine, and we also list a KWA KMP9/KMP9R NS2 series 20-round metal gas magazine separately; please check that spare magazines are NS2 compatible before ordering.
The Picatinny rails take standard 20mm optics, lights and lasers, and the 14mm CCW thread suits most mock silencers and tracer units. We also list KWA KMP9 parts such as NS2 disconnectors and a muzzle device separately.
Care and maintenance
Put a drop of silicone oil on the magazine’s fill valve and seals every few fills, and store magazines with a little gas in them so the seals stay seated. Do not overfill, and in cold weather let magazines warm up to room temperature rather than heating them.
Wipe the moving parts and outer barrel with a thin film of silicone oil now and then, clean the inner barrel with a rod and patch, and use good quality seamless BBs. Never use petroleum-based oils on the seals, and keep the pistol and magazines away from heat and direct sunlight.
Who is it for?
It is ideal for CQB specialists and anyone who wants a light, quick-handling gas SMG with real blowback and modern rail space, and it pairs well with a rifle as a compact secondary.
Please note: Gas and BBs are not listed as included; a US retailer lists the gun, one magazine and a manual in the box. Always wear suitable eye and face protection when using airsoft replicas, and check your site’s rules and power limits before play.
Please note: what's in the box can vary between batches. If a detail such as included magazines, battery, charger or connector type matters to you, contact us or call 01842 683567 and we'll confirm before you order.
