Nothing I said was useless or sarcastic. It is good advice that I have given to countless other new shooters, both in person and on the forum, and never had any complaints that I was being mean. In fact, I gave the same advice in your thread looking for a WML for your pistol and when it was all said and done, you thanked me for it.
What I said was 100% said to help, not discourage.
Also - point of order: After the answer of “yes”, it was you that continued the conversation trying to justify your assumption. If you didn’t respond, the thread would have ended there.
Anyway, good luck with the optic.
