  • High-density polymer build
  • 6.03mm Tightbore inner barrel
  • Vortex programmable ETU inside
This AEG is available in Pre Two-Tone Blue. If you order this colour option, you don't need to wait for our Two-tone service, and you don't need UKARA or a VCRA Defence to order.

If you're new to the sport seeking a competitive primary with a military-style look, the NUPROL Delta Vanguard M4/AR-15 Pathfinder AEG should be in your sights!

Made almost entirely from rock-solid high-density polymer, this M4/AR-15 AEG boasts proven internals with wide compatibility, an advanced electronic trigger unit and an incredibly light, agile build well suited to younger players and fast-moving playstyles.

On the outside, this budget-friendly build boasts an M4A1-style Triangular Front Sight, giving it the iconic front end we all recognise. The handguard is equipped with 20mm Picatinny rails for accessories, and the receiver includes a 20mm rail for a red dot sight or scope. The barrel is also threaded for a tracer unit or suppressor if you want a truly tactical look.

Inside, the Pathfinder is based around the proven Version 2 gearbox design, with an alloy shell, 18:1 ratio steel gears and a quick-change spring guide for easy maintenance. The cutting-edge Vortex ETU provides programmable fire modes like burst modes and binary trigger, and a tightbore inner barrel enhances accuracy with high-quality BBs.

Whether you have a military-style loadout planned or you want to get started with a platform more advanced than the usual beginner build, the NUPROL Delta Vanguard M4/AR-15 Pathfinder AEG is a great shout!

Quick Start Guide

  • Charge your Battery: We recommend a 7.4V 1450mAh LiPo battery for this AEG. Please note: a battery and charger are NOT included with this product. Plug your charger into a 3-Plug UK wall socket and connect the balance connector on your battery to the balance port on your LiPo charger. Your charger will cut off when your battery reaches capacity, but you should never leave it on charge unattended. We recommend using a Battery Safe Charging Bag for charging and storing your battery.
  • Fill your speed loader: Open the hatch on the top and pour BBs in. Press the button on the side to deploy the thumb plunger. A speed loader is required to load the included medium-capacity magazine. If you don't have one, find them here: Airsoft Speedloaders
  • Load your magazine: Position your speedloader to align with the port on the top of your magazine. Holding the speedloader firmly against the magazine, push the thumb plunger repeatedly until it becomes firm.
  • Put on your Eye Protection: Safety when using Airsoft guns should be your number 1 priority. Always wear eye protection before loading your AEG and ensure any spectators are also protected.
  • Connect your battery: Remove the butt plate from your stock by extending the stock, pressing the tabs on either side, then lifting it free. Inside the buffer tube, you'll find the Deans connector. Position each of the cell groups of your battery inside the tubes on either side of the stock, then connect the Deans connectors. With your wiring neatly tucked in, replace the butt plate.
  • Insert your magazine: With the fire selector switch set to "SAFE" and the barrel pointed in a safe direction with your finger off the trigger, insert your magazine by pushing it up into the magazine well.
  • You're now ready to shoot! - Never shoot at animals or humans who aren't in an Airsoft skirmish
  • If you want to program the Vortex ETU for different fire modes, check out the included programming instructions card.

About the Delta Vanguard M4/AR-15 Pathfinder AEG

Starting at the tip of the alloy outer barrel, we are met with an alloy birdcage flash hider with 14mm CCW male threading beneath. The common 14mm CCW male threading allows alternative flash hiders, tracers or suppressors to be mounted, a key feature for customisation.

Next up, we have the M4A1 triangle front sight, made from alloy with a sling loop built in. This means you can use standard strap slings, pairing the front sling loop with the rear loops on the stock or the sling plate at the rear of the receiver.

After the front sight, we come to the handguard, equipped with 20mm Picatinny rails on the top, bottom and sides. The side rails are equipped with rail covers, but these can be removed by pressing the tab at the end and sliding them off the rail. The 20mm rails allow you to add 20mm Picatinny accessories to the top, bottom and sides, should the mission require.

The receiver also features a 20mm Picatinny rail, allowing red dot sights or scopes to be mounted with ease. The Pathfinder features a fully adjustable polymer flip-up aperture rear iron sight pre-installed on this rail. To flip it up, press the tab at the rear of the sight, and it will spring into place instantly. If you use an optic, the rear sight can be left flipped down as a backup sight or removed entirely to save weight.

Next up, we reach the receiver, matching the popular M4/AR-15 rifle in terms of the controls and shape. The magazine release is on the right side of the magazine well and is accessible for a right-handed user with their trigger finger or by a lefty using their off-hand thumb.

The fire selector lever can be found just above the pistol grip, on the left side of the AEG, providing 3 modes of fire: SAFE, SEMI, and AUTO, with a 90-degree throw between each.

Pulling back the extended charging handle at the rear of the receiver provides access to the rotary HOP-up adjuster. The HOP-up allows you to adjust the amount of backspin applied to your BBs and extend range with heavier ammo, seeking the flattest possible trajectory.

The pistol grip is an M16A2/M4A1 style pistol grip, featuring diamond checkering on either side and linear texture on the back to provide excellent gripping qualities, whether you wear gloves or not. The finger ridge helps you keep hold of the rifle when held in a single hand.

At the rear, the Pathfinder is equipped with a unique A-frame stock with a quick-access battery compartment. The stock also features a pair of QD sling sockets, one on each side, allowing QD sling swivels to be fitted. Conventional sling slots are also present for those who prefer the old-fashioned way.

The adjustment lever is in the centre of the A-frame shape. To adjust the stock to any of the 6 adjustment positions, hold the lever down and slide the stock into your position of choice. This means you can adjust to suit your body type and any tactical gear you're wearing.

The butt plate is made from grippy rubber with a serrated design, ensuring your Pathfinder doesn't slip off your shoulder at a critical moment. If you decide you want a change or prefer another stock design, you'll be pleased to learn you can swap this stock for any M4/AR-15 AEG sliding stock to customise your build.

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.

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.
