For: (Discontinued) SRC Crane Stock for M4/M16Product Information:
There is no review yet, so I guess I will just write one.
My M4 does not use crane stock battery, so I don't know how big of a battery it can hold. However, the sturdiness of this stock is amazing. I replaced this with the wobbly LE stock of my Combat Machine M4, and the result is completely satisfying. First off, this stock comes with 2 butt plates, one standard, one with rubber padding, and as mentioned earlier, it has zero wobble. Not to mention, it is comfortable as well.
2 butt plates
No wobble on my M4
Two nobs on the battery compartment can fall off easy - just a caution
Color isn't too convincing - dark earthish? grayish? - but I don't think it is eye-searingly noticable.
