V1 EMR Rail from ALG, imported from the states.  Mounted, then removed/replaced before ever seeing use. Pair of small nicks on the inside of one of the 6 o/clock M-LOK slots where I was a tad over zealous with attaching an accessory, no effect to function and will never be seen, especially once mounted.

I've retained the old barrel nut, washers and screw set with my newer rail, so this one comes with brand new parts (and appropriate imperial spec allen key). The proprietary barrel nut wrench is not included, but if you have a decent tool box you'll manage fine. If necessary for your personal usage, Brownells UK have the ALG wrench for less than a tenner.

This will fit *some* airsoft guns like PTWs and WE GBBRs but most AEGs require the upper receiver thread to be changed to Real Steel spec.  That is a service I offer as well separately since I have the right die, but the tool is also available online for anyone to buy.

Price is all-in.  Everything else I have for sale is pictured here - https://flic.kr/s/aHsjPXJkHw
