Picatinny rails and the M-Lok system

[DLParis]

I'm awaiting my new 2nd gen 15-22 Sport, and have ordered a laser sight, forearm grip, bipod and flashlight. I've already received a picatinny rail pack, but are not specified as M-Lok.
My question is does the original picatinny rail need to be M-Lok specific? Or will I be ok with the original mounting hardware?
Thanks in advance,
D

I'm not sure what a "rail pack" might be.

Read up on the M-Lock setup on Magpul's website. You should then be able to tell what you need.
