Lightweight AEG Race Rifle


Airsoft is much more than just MilSim and one of the fastest rising branches of the sport is competitive timed shooting events.

Using specialized pistols, rifles and shotguns, shooters take on a predetermined course of targets, racing against the clock to try to score the fastest time. When building a race gun, light weight, accuracy and rapid trigger response take priority over velocity and extended range. We decided to put together an M4 AEG race rifle using some of the newest parts available from companies like Airsplat, G&G, ASG and PTS. To top it all off, we had the gun Cerakoted in a decidedly un-MilSim pure bright white color, to give it a distinctive flashy appearance sure to turn heads on the course. Let’s dive into this build and turn a normal M4 into something decidedly more awesome!

The plan for this build was to make a lightweight, yet still full metal and visually realistic M4 with snappy trigger response, excellent short-mid range accuracy and an ergonomic design using a tubular handguard, steeply angled pistol grip and other lightweight parts. We had a dream list of parts and were able to get most of those that we were looking for! Unfortunately, we did have one more part that we’d have liked to include in the build, a Deep Fire PTW type outer barrel and hop-up unit, but it just wouldn’t cooperate with the LCT receiver and gearbox.

AEG-p11When picking the base gun for this build, we wanted to go with something that hadn’t seen much attention from the industry yet and the LCT M4 series was a perfect option. We got ours from Airsplat, along with a few other parts. This AEG was priced on sale under $180 when we picked it up from Airsplat and in my testing before putting it together, it appears to be worth much more than that price. Normal retail price looks to be between $250 and $300 and honestly, I’d absolutely pay that for this rifle.

AEG-p2 2Lightweight parts such as the Trinity Force 10” Hanguard, MFT Minimalist stock, Element refl ex sight and PTS EPM help make the gun easy to handle as well as point and shoot. Also pictured is the Deep Fire outer barrel which unfortunately, we just couldn’t make work for this build.

AEG-p33The first steps on the build were to strip the gun down to the bare receivers to get it ready for Cerakoting. After separating the upper and lower receivers, we needed to remove the pistol grip. LCT has a nicely ventilated motor adjustment base and metal reinforced inner pistol grip brace.

AEG-p4 4Using a punch, the cosmetic faux bolt catch easily came free. Be sure not to scratch your receiver’s finish when doing this operation.

AEG-p5 5The LCT uses a captive pin design, so you have to push the spring pressurized retaining pin into the receiver to allow you to rotate and then remove the front pin. Make sure you bag and label your parts as you remove them!

AEG-p7 6The rear pin is retained using a cotter pin that can be easily removed by pulling it up with a punch or other tool. Once removed, the pin can slide free of the receiver.


7Removing the stock trigger guard is also a simple operation. Just use a punch to press out the rear pin and to push in the spring-retained pin at the front.
