help with parts selection requested
I'm wanting to put together a 300 whisper upper on an ar 15. It would include a 10.5 inch barrel, and preferably an adjustable gas block in the pistol location. Is there a quad rail handguard/free float tube with a big enough inside diameter so that I may use a rifle length handguard and my suppressor would partially fit inside the handguard? Thanks in advance. Bill
