Description
If you like sneaky styling but prefer a longer platform, the Lancer Tactical LT-15CB Gen.2 M4 SD 14.5" NSR AEG fits the bill. Styled similarly to other M4 SD AEGs but with a longer handguard and barrel, the LT-15CB features a 360mm tightbore inner barrel and 10-inch RIS handguard to provide extra rail space for accessories and a slight edge in accuracy, velocity and range over shorter variants.
A revamped version of the original LT-15CB M4 SD 14.5", the "NSR" version features a new receiver design patterned after real steel "billet" receivers, ambidextrous fire controls and an updated grip and stock design inspired by the latest and greatest real steel ergonomic furniture.
Inside, the version 2 gearbox features a reinforced alloy shell, 18:1 ratio steel gears running on 8mm bushings, a quick-change spring system for easy power tuning and a polymer piston with a full steel tooth rack. The inner barrel is a 6.03mm tightbore paired with a rotary-style HOP-up unit, providing competitive range and excellent accuracy potential when used with high-quality BBs. For skirmishers who value the stealthy look, this makes a fantastic beginner platform with wide compatibility with internal upgrades if you want more down the line!
Starting at the front end, we can find a pre-installed suppressor which covers the 380mm 6.03mm tightbore inner barrel, mounting to the 8.5-inch alloy outer barrel. This gives the LT-15CB integrally suppressed AR styling, ideal for sneaky skirmishers. The suppressor mounts to 14mm CCW male threading, but due to the extended inner barrel length, a barrel extension will be required to mount a tracer unit.
Surrounding the suppressor, we have a polymer 20mm Picatinny quad-railed handguard with 20mm rails at the 3, 6, 9 and 12 o'clock positions, ready for any 20mm accessories you choose to add to complete your mission. Styled after the real steel KAC RIS, the handguard has a realistic look and unlike similar integrally suppressed platforms with KeyMod or M-LOK handguards, you will never have trouble mounting mission essentials to this quad rail, as it doesn't require clearance between the handguard and suppressor.
The receiver of the LT-15CB is significantly styled up to match real steel "Billet" receivers, providing modern looks to pair with its ambidextrous fire controls. The fire selector is positioned just above the pistol grip on either side and offers 3 modes of fire: SAFE, SEMI and AUTO, with a 90-degree throw between each mode. This makes the selector easy to switch, but not so easy that it can be knocked out of position accidentally. The fire selector is also an enhanced design, and this, paired with its ambidextrous functionality, makes it fantastic for use in all weather, with or without gloves, left or right-handed!
The magazine release is on the right side of the magazine well and is also an extended design with a secondary mag release on the opposite side, accessible for either left or right-handed users with the tip of the trigger finger. The charging handle, located at the top rear of the receiver, is also ambidextrous, allowing it to be pulled from either side with a single finger, in line with modern AR-15 shooting doctrine. Ambidextrous controls are the primary improvement in Lancer's Gen.2 NSR line, providing a more advanced look and ensuring left-handed shooters are at no disadvantage.
Pulling back the charging handle will open the dust cover and retract the mock bolt carrier to allow access to the rotary HOP-up adjuster. This is the latest HOP-up unit design for the M4/AR15 and provides finer increments of adjustment and holds its setting more effectively when compared to the older gear-style HOP-up unit.
The trigger is a flat-style trigger, pairing well with the modernised "billet" style receiver. The trigger guard is an enlarged and built into the receiver, which allows easy access to the trigger when wearing gloves and improves the overall strength of the receiver. The pistol grip is a modern ergonomic design with a filled backstrap and a reduced grip angle, allowing for more comfortable shooting in CQB when you are running the stock fully collapsed.
The LT-15CB also includes a dummy forward assist button to keep the rifle looking faithful to the real M4/AR-15 platform. Present on the right side of the upper receiver, the forward assist is a separate moving part which can be pressed in but does not affect the function of the AEG.
At the rear of the receiver, we are treated to an ambidextrous sling plate, which is constructed from steel, providing ample strength to support the M4 SD on a single-point sling. This sling point can also be paired with a front sling point (available separately) if you prefer a two-point sling setup for better stability when moving with the rifle stowed. The high-density polymer AR buffer tube mounts directly following the sling point, offering 6 positions of adjustment for the Lancer Tactical "NSR" stock, making it suitable for any body type.
The NSR stock can be adjusted by holding the adjustment lever on the bottom of the stock and pulling the stock out to the desired length. A modern, low profile design with a rolled toe for ease of use with body armour, the NSR is a fantastic stock, taking inspiration from some of the latest and greatest real steel designs. The butt plate is rubber, offering plenty of grip for wet-weather skirmishes, and the adjustment lever has texture on it to ensure you can make effective stock adjustments in the field.
The battery compartment of the LT-15CB is inside either the buffer tube or the crane stock, and the choice of which you use depends on your battery. If you are using the buffer tube, a 7.4V 1200mAh LiPo stick battery is ideal, though you may need to leave the stock extended in order to fit it comfortably. To get into the buffer tube, simply pull the stock adjustment lever out and with it held in place, the stock can be slid off entirely to the rear.
The other option is to make use of the battery compartment inside the stock itself, which can be accessed by pressing the two protruding tabs at the toe of the stock and then pushing them through. With this done, the butt plate can be lifted free, revealing a mini-Tamiya battery connector to which you mount your battery. If you are stowing your battery inside the NSR stock, you can fit a 7.4V 1300mAh LiPo in nunchuck configuration. Included in the set, we are also treated to a 9.6V 1600mAh NiMh battery to get you going, though you will need a NiMh charger to charge it.
If you're seeking a lightweight build which is easy to carry and accessory-ready, the Lancer Tactical LT-15CB Gen.2 M4 SD 14.5" NSR AEG should be in your sights. With an ergonomic edge thanks to its superb "NSR" furniture set, proven internals which are fully upgradable and a stylish new receiver design with enhanced ambidextrous controls, Lancer has really upped its game!

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.
