Is it necessary to dimple a barrel?
Is it necessary to dimple a barrel?
Since most customers do not use a dimple, adding an unprotected path for corrosion is not advisable. The dimple pattern is not standard across the industry. If we added it in production for all barrels, it would add a full operation for itself, increasing lead times, cost, and price to the customer.
What is the purpose of fluting a barrel?
The main purpose of fluting is to reduce weight, and to a lesser extent increase rigidity for a given total weight or increase surface area to make the barrels less susceptible for overheating for a given total weight.
Does Aero Precision dimple their barrels?
I ordered my Aero Precision barrel today and found out they don’t dimple their barrels for the gas block.
How much weight does a fluted barrel save?
Fluting: Bolts get you an ounce at most. More looks than weight savings. Barrels can save you anywhere from 4-10oz depending on contour, flute depth/count/design.
Are fluted barrels lighter?
Conclusion: the fluted barrel is much lighter, much less rigid, and has much more surface area than a solid barrel of the same diameter.
Does fluting make a barrel stronger?
All About Fluting & Dimpling. Fluted barrels are simple in concept, but seem to be the source of a lot of misunderstanding and controversy. Some people will tell you that fluting makes a barrel stronger or more rigid. Some will tell you it improves barrel cooling.
How does barrel weight affect point of Impact?
If a barrel contains unresolved stresses from manufacturing it can expand unevenly or warp, which also affects point of impact (POI) as well as group size. A heavier barrel contains a lot more thermal mass, which means the heat can be spread into more steel, heating the barrel less overall.
What are the different barrel profiles for the AR-15?
Besides the A1 “pencil” and A2 barrel profiles, there are two more recent significant developments: The “S2W” (strength-to-weight [ratio]) barrel, a CHF barrel by Daniel Defense, sold with a chromed bore, and the “ELW” (enhanced lightweight) profile from Bravo Company Mfg.
Why was the M16A2 given a heavier barrel profile?
At the request of the Marines the M16A2 was given a chromed bore and a heavier barrel profile forward of the gas block, mainly to minimize the chance of bending (one of the A1’s most common failures in close combat). This profile is now commonly called “A2”.
