Good evening guys ! hope this is in the right section as this falls into all of them really , I'm looking at getting a scar l always wanted one and it will go nicely with my load out this year , now iv seen a lot of hype over these SMP drop in kits to convert AEG's to hpa set up this interests me a lot however when then going to hpa id like the blowback , recoil , cock back , release etc etc the only one off the top of my head i can think of is the TM scar - L which has a unique blowback system as far as i know its something to do with a weight on top of the gear box my question is would this still work with a SMP kit installed ? can't seem to find any detailed videos or threads on how that system works on the TM. TIA
