I was wondering what was the purpose of the t- markings on the upper receiver.
Is it a marking system so you can put a buis or scope back on in the same place?
I claim ignorance.hinking.gif Thanks for your help.

Pretty much.

T means..........................................................................wait for it ......................................................................................here it comes .........................................................................TOP

I bet you can guess what "R" "L" and "B" stand for on some rail systems now

You are correct that they are used for the replacement of rail-mounted accessories (mainly takling about optics) in the same spot so they will be as close to return-to-zero as possible.

Yes. The markings are so you can place the BUIS, mount, etc... back in the same place for repeat accuracy/placement. Same as for the L,R, & B markings on a quad rail. It takes the guessing out when you remove your BUIS, mount, etc... for celaning/maintainance.

Thanks for the info. I was kind of hoping it would be some really neat reason why they were there, but this answers my question.[

Off topic, but WTF is that above. It looks like a smiley on the phone. I've seen more than one person post this. Is it a random typo that catches more than a few people, or some secret society symbol. I gotta know, dammit!!!!

LOL!!! fricken Mongo, dude, you're so funny... I started laughing when I read that post and looked at the smiley. Funny shit, man.[

ETA: To stay OT... I told a friend that the white RAS markings were there so soldiers can see them at night incase they need to mount equip. in the dark..................and he believed me. (I better call him on it before he starts rumors) LOL
