You must not have known that many Soviet citizens did have guns, and military service offered access to even more. It was immaterial.
What you are also missing about state sponsored religion is that by using public funds (your money) the government is sponsoring a particular faith on your behalf, and in so doing negatively affecting the influence of the religions they do not sponsor.
Don't confuse "state" with "government". We are the state and the government is the administration that runs the state for us. The government is not empowered to advocate for any religion because the state is granted no power to hurt or help specific faiths. Since there is no factor that is universal to all belief systems (including atheism), there can be no equitable way for the state to sponsor all faiths equally.
