KIDD Match Bull Barrel, 20″, Stainless Steel

Barrel installation: 

Depending on your receiver, if there is paint build up in the receiver mortise be sure to scrape that out. It is recommended to use an anti-seize compound to assist in installation. Anti-seize is readily available at automotive stores.  It is best if you can get the barrel tenon started into the receiver mortise, then turn it over and tap the back of the receiver with a rubber mallet. Be sure to line the extractor slot up as you are installing the barrel. Your barrel is ready to shoot, just run two magazines through it before you really start looking at group size. Do this each time you change brands of ammunition as well. Keep the chamber clean, but don’t clean the bore too much you will decrease accuracy. Depending on the ammo, clean the bore around every 500 rounds.

Avoiding “barrel droop”:

First and foremost barrel droop is eliminated with a solid fit between the barrel and the receiver.  If the barrel slips in too easily then the shooter should already be aware that there is not a secure fit and gravity will start doing her work immediately.  Or if the barrn motion.  For instance if the breach end of the tenon is smaller than the shoulder end the weight of the barrel will “pull” the barrel down and barrel droop is created.  Or if the breach end of the tenon is larger than the shoulder end then as the tenon is installed in the mortise the breach carves a larger hole and again a teeter totter effect is created as the smaller shoulder end of the tenon sits is a hole that is too large.  This same effect would happen if the middle of the barrel tenon was enlarged.
