Description

The EMG Strike Industries 15" Sentinel M4/AR-15 AEG w/GRIDLOK Handguard doesn’t just perform, it stands out. With its aggressive, officially licensed Strike Industries furniture, this M4 is built for players who want to make a statement on the field. Strike Industries is known for bold aesthetics and smart ergonomics, and this replica showcases both flawlessly.

Starting at the front of this platform, we can find an EMG replica of the Strike Industries Oppressor LITE Universal Blast Shield. This aluminium muzzle device gives the front end an extremely aggressive style and also creates a booming muzzle report every time you shoot it. If that doesn't impress you, underneath you will find 14mm CCW threading.

Behind that, we get to the main attraction, the GRIDLOK handguard. This Strike Industries masterpiece is built from CNC-machined aluminium, ensuring a rock-solid and reliable fit. When it comes to mounting options, you’re well covered. The handguard features a Picatinny rail along the top, M-LOK slots on the top, sides, and bottom, and an M-LOK/Picatinny hybrid section positioned at the front underside of the handguard for extra versatility.

The handguard includes QD sling points on both sides, along with officially licensed Strike Industries and GRIDLOK trademarks. These markings are laser-engraved, ensuring they won’t wear away through regular use and remain far more visible than standard printed trades.

At the top of the handguard is a recessed flip-up front iron sight. When not in use, it folds neatly into the handguard for a streamlined profile. Its elevation can be adjusted using the screw at the front. This works in tandem with the King Arms rear folding battle sight, which offers adjustable windage and two differently sized apertures to suit various engagement ranges.

The charging handle can be pulled to open the ejection port and lock back the mock bolt, granting you access to the HOP-up unit. Once you have adjusted your HOP, you can press the Enhanced Bolt Catch Release to send the mock bolt back with a satisfying "ring"!

Moving on to the receiver now, it follows the standard M4 layout with all the controls being exactly where you'd expect. However, it does replace the standard pieces with enhanced Strike Industries furniture. This makes all the controls easier to use, as they all have a gripping texture as well as an enlarged design.

The trigger of this rifle boasts a flat design with a lip at the bottom of it. This makes rapid double-taps easy, perfect for some semi-auto gameplay, whether that's in CQB or as a DMR. Underneath the trigger, there is the Strike Industries Cobra Billet Aluminium Trigger Guard. This helps you guide your magazine in and provides a comfortable place to rest your finger off the trigger.

The pistol grip is known as the Strike Industries "MilSim" Enhanced Slim Grip. Its slim and low-profile design accurately mimics the look and feel of a real pistol grip. It has a textured crackle design on both flanks with a horizontal line design on the front and rear. The 25-degree angled design makes it extremely comfortable to use whilst on the battlefield.

Moving rearwards, we come to the EMG ALPHA Combat Ready Stock. It is made from nylon-reinforced polymer with a rubber butt plate and a low-profile cheek rest for a solid cheek weld. It features sling loop cutouts and a spacious battery compartment that fits most nunchuck, crane-style batteries.

Internally, the EMG Strike Industries 15" Sentinel M4/AR-15 AEG w/GRIDLOK Handguard is packing quite a punch. Its version 2 gearbox comes with CNC high-strength gears, a high torque neodymium motor and a preinstalled GATE ASTER SE MOSFET. This MOSFET allows you to program binary or burst modes as well as adjust your trigger sensitivity between 250 settings for ultimate control over your replica.

If you're looking for a sleek, modern assault rifle with just enough aggression in its design, the EMG Strike Industries 15" Sentinel M4/AR-15 AEG w/GRIDLOK Handguard should be at the top of your list! Its licensed Strike Industries furniture provides both form and function, plus its internals make it a great skirmish contender straight out of the box!

Joule Charts

Special Instructions

These table can be used as a reference to see if the BB weight you are using will be over acceptable Joulage limits at some Airsoft Sites in the UK. To check if the weight can be used chrono your weapon using the BB you intend to use, and then compare it to the chart.

FPS, Power and Joule Limits can vary from site to site, so please get in touch with where you're going to play with in advance to avoid disappointment.

Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, with a 350fps limit for Automatic Replicas, 400fps for Semi-Automatic Replicas, and 500fps for Bolt Action Replicas.

Tap the tabs below to open the relevant chart for your replica.

This table should be used for reference, and cannot be used to check one weight against another, as the weight of the BB affects the power.

In order to check if the BB can be used with your replica chronograph using the weight you wish to use and then compare it against the table.

Every time you change weights you will need to re-chrono and check against the table. This is not a conversion chart between weights.

Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, and is the equivalent of 350fps, using 0.20g BB resulting in an upper limit of 1.14j.
