Sure you can. However the title and question you asked about was removing the hand guard. If all you want to do is thread the suppressor on, just take the flash can off and thread the suppressor on. Be sure you have a fixed barrel spacer on the suppressor...wouldn't want any baffle strikes on the new can.
Thanks, yeah I see what you mean now, after looking at it last night, I just assumed you can take off the threaded fake can ,and just thread on my adapter and the suppressor. Now you have me googling for this spacer. which I came up with this ? >
https://www.store.silencerco.com/products/fixed-barrel-spacer?variant=221756540 I was sorta wondering if anything needed to go inside the can, per at the gun shop and reading the paperwork that came with the suppressor, it just shows to remove the cap, and the spring, and then thread on the adapter for the barrel and thread on the suppressor , which leaves this pocket inside the can where nothing is except bullet travel. But, the store, and the paperwork both state you dont need the piston adapter because thats for a pistol, not a threaded barrel, hence why i thought you could just thread on the suppressor and be good to go. So I actually need this spacer to sit inside the can? because it seems it will just float in there freely, possibly causing more of an issue then if its not.
Forgive my ignorance here, I haven't looked into this as much as I thought I have it turns out.. I was under the impression with emailing silencer-co and looking at a few things online to suggest its just as easy as taking off the fake can, and threading on the real can with the adapter. Which is another issue of spending almost $800 on a can ,and not getting all the parts needed to make it work.
