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.

same placement of gear when removed and re-installed.

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.[
