Fitting a 12.5” EMG fsp rail to a TM NGRS

[Ben_TA455]

Hi everyone I’m hoping someone can help! I want to fit a 12.5” Daniel Defense FSP style rail to my Tokyo marui m4 Sopmod NGRS. Has anyone done this before and if so what do I need to buy to do it? I’ve read a few different things online of varying parts required so want to get some clarity before I go ordering stuff!

Can't speak for that specific rail, but i've fitted various rails to NGRSs and usually it's pretty direct except needing a large "washer" to go inside the new barrel nut as NGRS barrels typically slip through AEG barrel nuts.
