The KWA LM4 Series semi-tightbore 258mm 6.05mm brass inner barrel is made of the highest quality material and is meticulously crafted to precise specifications. With this inner barrel, you can customize your LM4 Series rifle for close-quarters play, or you can shorten your LM4 or LM4 RIS inner barrel in preparation for a mock suppressor/barrel extension. The possibilities are endless!
Although this barrel is the stock inner barrel for the LM4C PTR, it can be used in any LM4 Series rifle!
