Barrel Bushing compensator?

It is sold by Cdnninvestments but I cant find it on there page, the ad says, built in extended compensator. For $20 it might be a fun thing to try out. Would it be a drop in part for a 70 series government model?
 
The barrel bushing is rarely a "drop-in" part, at least if you want maximum accuracy. For accuracy, the bushing is normally undersized, and it's sized to fit the barrel.
 
If it is a barrel bushing compensator, yoy will not gain much by using it. Perhaps a little more muzzle weight but that would be it. For a comp to work correctly the bore of the comp has to be just a tiny bit larger than the bullet diameter. The bullet would block the gasses from escaping out the front of the comp and they would be forced out the vents/ports. With a compensator that has its bore larger than the barrel outer diameter, the gasses would be allowed to flow/blow past the bullet and not be deflected out the ports.

BTDT, sold the paperweight.
 
I tried a barrel bushing compensator years ago. It was one of those that looked like a regular bushing but with a tubular extension with three slots cut into the top. It definitely decreased the accuracy of the 1911 that I used. I could not get a tight barrel to bushing fit and still have the gun function smoothly. It also did not significantly decrease felt recoil or muzzle rise. In the end, it was relegated to the pile of failed parts and experiments. If you want a compensator that works get one that is attached to the barrel and has a muzzle opening that is just a few thousandths of an inch larger than the diameter of the bullet. A lot of manufacturers make drop in style barrel kits that do represent a decent value.
