Our Promise:  KWA airsoft guns are renowned for their world-class performance and exceptional build quality.  With an exceptional 45-day factory warranty and LIFETIME tech support offered directly through KWA, we feel most qualified to be YOUR premier KWA dealer.  In addition, you are guaranteed to pay the absolute LOWEST price on the market for your new KWA rifle, backed in writing by our industry-leading 125% Lowest Price Guarantee.

Our take:  This NEW KWA Magpul PTS LM4 PTR combines KWA's industry leading gas blowback rifle with modern ergonomic Magpul PTS furniture and a licensed Magpul lower receiver, making this rifle one of the most realistic and tactical looking GBBRs on the market. KWA’s NEW LM4 PTR (Professional Training Rifle) brings the realism of gas blowback airsoft rifles to a new level.  From its authentic design and construction to its realistic operations, the LM4 PTR is in a league of its own.  Faithfully mimicking real steel M4 operations, the KWA LM4 is perfect for real world training.  Not only does this gas blowback rifle operate nearly identically to a real steel M4, it also field strips (disassembles) just like a standard M4 carbine.  This makes it easy to clean and repair the LM4 PTR without the use of tools, which is especially helpful out in the field.

KWA has redeveloped their renowned NS2 system and made it compatible for larger scale gas blowback rifles. The new system, aptly named the “Force Velocity System”, gives the KWA LM4 PTR vastly superior power, recoil, and gas efficiency compared to other gas blowback airsoft rifle on the market.  These truly amazing gas blowback rifles are available in limited quantities, so pick up yours today and join in the evolution of airsoft!

LICENSED MAGPUL PTS EXTERNALS
The KWA Magpul PTS LM4 PTR design is modeled after the Magpul M4 MOE Carbine, featuring a unique Magpul licensed lower receiver and complete Magpul PTS MOE furniture. Crafted from CNC aluminum and designed to withstand real world training situations, this GBBR is the ultimate platform for realistic training scenarios.  The MOE stock, pistol grip, and hand guard are constructed of high grade impact resistant nylon polymer, and are made to nearly the same standards as real steel Magpul furniture.  This gives the Magpul PTS LM4 PTR a modern and ergonomic look and feel.  Additionally, the LM4 PTR features a top optics rail for attaching a variety of red dot sights and magnified scopes, and also includes a Magpul PTS rear MBUS sight.  The six position retractable MOE stock allows you to adjust the stock to your preferred shooting stance and makes the gas blowback rifle comfortable to shoulder. 

What really sets the KWA Magpul PTS LM4 PTR apart from other gas blowback rifles on the market is its hyper realistic feel and functionality.  Slapping the bolt catch sends the bolt home with a snap, closely copying the feel of a real M4 carbine.  Just like a real M4 carbine, the LM4 PTR stops firing once the magazine is empty, and locks the bolt to the rear.  This is perfect for real world training simulations, allowing you to train accurately with a high power premium airsoft rifle.  Also similar to a real M4 carbine is the trigger assembly and selector group, which only allows you to switch to “safe” after the bolt has been charged.  These extremely realistic functions, combined with a flawless authentic exterior, truly make the KWA LM4 PTR the best choice for tactical training and MILSIM airsoft players.

NEW INNOVATIVE INTERNALS
The KWA LM4 PTR utilizes the new “Force Velocity System”, which adapts and improves KWA’s renowned NS2 gas blowback system for larger, more powerful gas blowback rifles and sub-machine guns, giving them greater reliability and hard kicking recoil!  KWA’s “Force Velocity System” also greatly enhances gas efficiency, allowing you to fire up to three magazines worth of rounds from a single gas charge!  Firing the KWA LM4 PTR gas blowback rifle for the first time can startle you with its hyper realistic recoil, providing more kick than a buffer tube equipped .22LR rifle!  This enhanced recoil feature is perfect for airsoft players and professionals who want to train with a system that closely mimics the kick of a real firearm.

Unlike many other airsoft gas blowback M4 carbines, the KWA LM4 PTR features a robust full metal bolt, with a reinforced piston, and a full metal feeding lip!  What does this mean for the user?  It means that this bolt is built to withstand intense real world training simulations, and is much less prone to chip or wear over time!  With a high flow KWA patented piston and jet nozzle, this gas blowback carbine fires at an incredible velocity (380-420 FPS w/ 0.20g BB’s), with a realistic rate of fire.  The hop up system is very similar to KWA’s NS2 system, which can easily hit targets out to 170 feet using 0.30g BB’s.  This is perfect for airsoft players who are tired of airsoft guns with shorter range, and want to knock down targets at close to realistic ranges.  With re-engineered, enhanced, and reinforced internals, the KWA LM4 PTR is truly designed for professional training, and can easily handle the most intense airsoft combat!

Whether you are a military/ law enforcement professional or a weekend warrior, the LM4 PTR is designed to closely replicate the feel and functionality of a real M4 carbine, helping you train accurately for a fraction of the price of real steel training equipment.  This KWA LM4 PTR truly is the next step in the evolution of airsoft.  Don’t miss out on your opportunity to own one of the most game changing airsoft guns on the market!

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
