M4 to spr barrel nut?

[Pewpewpetie]

Hi all. I have a specna arms SA b03 V2 and wanted to do a lone survivor build. Internally I'm competent but when it comes to externals I'm not so. My current handguard is mounted via 2 Allen key bolts and wondered would guard with barrel nut be compatible. If so where could I pick one up. Thanks
