I'm in the market for another 16" carbine gas system barrel (either 16" or 14.5" + pinned FH and 1:7 or 1:8 twist). I want to get something pretty awesome, so I've seen that AIM has the DD CHF barrels for sale. The price on these is not as kind to my budget-minded side, but it seems like there aren't many other mfgs who produce CHF barrels. But this makes me think, besides theoretical extended reliability due to the way the bore is created, is cold hammer forging something to actively look for when buying a barrel? Or, it is just something that is nice to have in the event the barrel fits my needs in terms of general specifications and the reputation of the manufacturer? Does the CHF process make a barrel that is technically more accurate than say one that is cut rifled? |

On my phone so I can't give the complete answer, but the short answer is a button rifled or cut rifled barrel has more potential to be more accurate than a CHF barrel, due in most part to the extra stress relieving needed to finish a CHF barrel. There are very many variables involved, and it isnt going to be a cut and dry answer across the board (exact accuracy comparisons would have to be compared on an individual basis) but as a rule it is easier, and more likely to have a more accurate barrel that is NOT CHFed
As was said earlier, google it. It's a complicated process what determines the finished product and it's not an easy answer to say which is has more accuracy potential |

Quoted: CHF = inherently more concentric bore and free of defects = ACCURATE M4QUADRAIL  google CHF Barrel process  It also means more stress hammered into the steel that cannot easily be released. Also Hammer Forging is not inherently more concentric, it is consistently more concentric. Inherently is not the same thing as consistency... Both manufacturing processes have their advantages and weaknesses... |
