The kit includes: 1 two part blank barrel, 1 set of 8-12 various aperture set screw blank adapters, 1 Allen wrench, and 1 muzzle cone replacement block.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe two piece barrel set up is one of the best ways to blank adapt your full auto or semi-auto MG42. For the gun to cycle, the barrel normally floats within the shroud traveling with the bolt for a short distance before unlocking from the bolt and returning to the forward firing position. \u003cstrong\u003eThe advantage of the 2 piece design is that, rather than moving the entire weight of the full barrel, only the much lighter rear section must travel back with the bolt.\u003c\/strong\u003e This is significantly easier for a blank cartridge to do allowing for better blank adapting. More flash, more bang going out of the front of the gun rather than being used up just to operate it. Our muzzle cone replacement block is designed to vent gas forward rather than channeling it back towards the barrel, allowing the 2 pieces of the barrel to work together rather than fight each other. To adjust the back pressure for blanks you simple change out the set screws in the end on the barrel allowing for easy and relatively quick adjustments for various powder loads.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWe also offer the booster cone replacement piece separately as well as the set of 8 set screws.\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSo if you already use a 2 piece barrel replacing this part should make your MG fire blanks much better. It makes the 2 piece barrel more efficient. Please note that when you are using a 2 piece barrel you should NEVER have any kind of restriction in the booster cone. This only makes the 2 piece barrel fight itself!\u003cspan\u003e The restriction should be in the forward part of the 2 piece barrel so that all the gas pressure is used to operate\u003c\/span\u003e\u003cspan\u003e the smaller rear chamber piece.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis item can NOT be shipped internationally - all non-US orders will be canceled! \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003eINSTALLATION NOTES:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOnce your barrel and muzzle cone are removed and the booster cone is off; install the two piece blank barrel basically the same way your regular barrel is installed.\u003cspan\u003e \u003c\/span\u003eThen, slide the muzzle cone replacement block over the barrel bushing.
