Also just added to the site’s project section now is a simple solution to creating your own milsim style mags written by WMH entitled ‘RealCap‘. The project shows you how to convert a standard Tokyo Marui M16/4 low capacity magazine so that it will only store a maximum number of rounds so that it corresponds to the number in weapon’s real-world counterpart.
The Tokyo Marui Standard M16 Series Magazine (popularly known as the TM Low-Cap) holds 68 BBs. It is however, a replica of a 30 round M16 Magazine. This guide will show you how to correct this error in realism.
This modification is based on an age-old concept. Here in the USA shotgun capacity is limited in certain types of hunting, and I’ve seen hunting shotguns come with magazine limiters — in the form of a wooden dowel, which inserts into the magazine follower and physically blocks capacity. This is what we will be doing here, using a small screw to physically block the magazine spring.
