Our take: This factory original spare KWA LM4 PTR Gas Blowback Rifle spare magazine is designed specifically for the KWA LM4 Gas Blowback Rifle. KWA has designed the LM4 magazine to replicate the real weight of a fully loaded thirty round STANAG magazine, giving your LM4 a realistic weight and feel. The magazine has a large gas reservoir capable of holding more than enough gas to empty your entire magazine. The magazine also has a 38 round capacity, which is perfect for most MilSim airsoft games. This magazine is constructed entirely of high grade metal and has a reinforced nozzle and magazine feeding lip. This is a must have if you are using the KWA LM4 PTR Gas Blowback Rifle!
Note: Filling the magazine OVER 40 rounds can damage the magazine. DO NOT USE PROPANE OR RED GAS with this KWA LM4 GBB Airsoft Rifle Magazine. Using propane or red gas with this rifle will void the manufacturer's warranty, and can cause irreparable damage to the rifle.
