There are four models and in each model it has two gas blocks attached to the gas tubes. How do we know what’s what? Why are there different prices? — 3 Answers

No! Ethan the Gear Expert answer is wrong. Per manufacturer SKU:11.03.06 is Carbine length NOT Mid-length! I didn't check the rest but probably wrong too.

I'm placing this answer here to hopefully gain a little attention to a possible issue. the Answer given here seems to be ether incorrect, or more likely there's a typo/error on checkout. When placing Model (11.03.08) in cart it states its rifle length?(11.03.07)Mid, (11.03.06)Carbine and (11.03.05)Pistol. So If the website has it incorrectly labeled then please correct and remove my Answer here. If the Previous Answer is incorrect then simply remove that response and leave mine.
