You can comment, just don't write as if you genuinely know what you're talking about. Feel free to discuss something you don't understand, but I don't see much point in it myself.
I wouldn't even be so generous as to say half are ill-informed (By the sounds of it you're going to have had one of, if not the most experience with assault rifles). You're more likely to find it's the heavy majority who have NO experience with automatic weapons what-so-ever (Unless this is the one thread that happened to attract every member of the Armed forces on OCUK

). Let alone enough experience to make an informed judgement call (As you're all making it sound like you're doing) as to the suitability of sentry guard weaponry.
Honestly it's halrious. Thread should be subtitled "Armchair experts only". I may have to give it 5 stars.
What's the point indeed.
You can discuss anything, just please for the love of sanity do it from a position of realism. Sounding like you're informed on a subject you're obviously not is just sad. It reeks of Internetz.
