Noveske NSR and SWS anti-rotation pin; Same Location?

[LoneStarM1A]

Hi,

I have a Noveske 14.5" midlength "lo pro" upper with the SWS quad rail and a pinned AAC blackout flash suppressor.

I recently received my SBR stamp from the ATF and an NSR rail from brownells.

I am going to send the upper to a company called adco to remove the pinned flash suppressor, remove the SWS rail, and install the NSR rail.

My question is, do the NSR and SWS rails have their anti rotation pins in the same location, or would a new hole need to be drilled into my upper receiver for the NSR?

Thanks in advance.

Both SWS and NSR have the anti-rotation pin right above the gas tube so I'm pretty sure they are the same since they both interface to the same uppers. I've never taken my SWS rail off of my upper so I am not positive though.

and if you decide to sell that SWS rail please let me know. I'm trying to put together an upper.

Thanks
