Hi, All -
I am changing a barrel on one of my uppers. The new barrel will have a low profile gas block. My question is, should the barrel be "dimpled" where the set screws turn in? Can you purchase a barrel that is already dimpled? Is this something that should be handled by a gunsmith, or is it DIY? |
| Some barrels have dimples, but it's easy to do yourself. Put it on and tighten the screws, shoot a hundred rounds through it to make sure it works. Then just remove one screw, drill until you have a little dimple, put some loctite on the screw, tighten it up. Repeat with the other screw(s). Hope this helps |

Can you purchase a barrel that is already dimpled? Is this something that should be handled by a gunsmith, or is it DIY? Many barrels come dimpled. Some manufacturers/dealers will give you the option (like Rainier). If you get a barrel that isn't dimpled it is very easy to do yourself. I've used THIS GAS BLOCK DIMPLING JIG with great results multiple times. Just follow the instructions. There is also a DECENT VIDEO DEMONSTRATION. It is kind of pricey but worth it –– even if you do one barrel. I'd use a little ROCKSETT on the set screws. |

Great answers and suggestions, Guys. Can you reccomend a good 18" barrel? BCM 410SS barrels with rifle length gas sytem. Rugged tack driver. I prefer the coated barrel to the 'shiny' one. I had mine coated by CLUB Custom Guns who preps the barrel by media blasting it first. This gives the coat a nice satin finish. |

Looking back I wish I would have gotten an 18". I sent it off to springer precision to get ion bonded. it seems like BCM never has the coated 410SS barrels in stock. |

They have –– I've seen them in person. I think others can do a better job coating them. I have a couple of them and my 18" 410SS barrel did well for me in a Magpul SPR class. |
