I don't want to remove it, I just want to know how. Just like no one ever wants to change a tire in the rain, but you need to know how.

does removing that guard require loosening or removing the barrel then? does the barrel just pop out or is it screwed in like an M1?

Hi. I’m new to the whole AR platform, though I’m very familiar and own many M1 Garand’s, M1A’s, M700, R742, and R750 rifles. I’ve never been a fan of the AR because they just look cheap and chintzy and sort of like a star wars Stormtrooper blaster. I’m also not a fan of the 5.56 round, I prefer the 30-06. Now that being said I ran into an AR last week, it’s a DPMS LR-G2 in 7.62x51 (which I see is the same as .308) and it looked and felt nice. It had heft but wasn’t heavy, it had nice metal parts, and it didn’t have that overly tactical military look. Well it was either that or another Springfield M1A … so I left. Then I went back an hour later and bought the DPMS. Now being to new the AR platform I have some questions … and to be honest even though there are 10 billion webpages that use the term “AR” … I haven’t found much helpful. Additionally the dealer that sold me the firearm didn’t know too much about it … (which is typical) … and Panther Arms really sucks ass when asking questions and more or less don’t respond to customer questions. Well here I am to ask some questions. Just to tell you a little more about myself, I do restore old WW2 firearms American for sure but I know my way around German arms and some Japanese/Russian stuff. I also consider myself an amateur gunsmith and can do most anything on a lot of pistols and other firearm types. So first here are the pics of the rifle as you folks probably want to see it. I have optics on the way. My first question is in regards to the label “Caliber – Multi” on the lower stamped on the mag well. Now I have learned as much as this means I can use a different upper and change the caliber of round discharged … what I haven’t found out exactly would be what caliber of round I can use … what uppers are available, and do I need to use the same magazine and such. Does this only apply to the Winchester .308 family of cases? I thought I read somewhere that you can get use 9mm or a .50 BMG (which I can’t understand as it is a far longer round then the mag well). Anyway, if you guys can explain this to me or point me to a place that could that would be a big help. Pics below. My second question is in regards to removing things. I assume you push out the two pins at the front and rear of the lower on the side of the bolt catch and it comes apart to separate the upper from the lower. What I don’t know is how do you remove the hand guard? I want to know how to remove it just so I know how to remove it. I looks to me like you need to remove the gas block and gas tub (which I read was a pain in the dick) before you can do that. That gas tube seems to pass through some cylindrical thing with tiny holes drilled in it and it passes through one of the holes (sorry I don’t know what that is called). I’ve read that you need custom DPMS tools to do this (and they don’t respond to customers) and that you need to heat the poop out of it with a torch. Any thoughts. Pics below. Thanks in advance guys.
