What size barrel do I need for a 3 gun?
In a three-gun competition, a 16-inch barrel provides good maneuverability. It’s also easy to buy and build, as this legal size isn’t highly regulated like other barrel lengths.
IS 16 in barrel too long?
The 16” barrel is perfect because it’s not too long where you’re losing accuracy, but it’s not too short where you’re losing velocity effectiveness. Now, when it comes to range, this isn’t necessarily the case. For long-range targets, the longer the barrel the better.
Are longer gun barrels more accurate?
As long as you know your velocity—and your bullet’s ballistic coefficient—you can know your trajectory. Longer barrels are not more accurate. If anything, it’s quite the opposite. Shorter, stiffer barrels tend to vibrate more consistently and are probably more accurate on average.
Are shorter barrels more accurate?
Overall, as demonstrated in the accuracy charts, the shortest barrel length provided the most consistent accuracy across the board and the longest length proved to be the least accurate with the same loads. The data also shows that the so called “MOA” a rifle can shoot changes with distance.
Does the military use 16 inch barrels?
The newer M4 was shortened to make handling easier, with a 14.5″ barrel standard in the military version, though civilian rifle barrels are generally required to be 16″ or longer.
What are the benefits of a longer barrel?
-Longer barrel means the sight is further and thus one can make more precise shots because the two aligning marks are further, and thus in order to seem aligned to the eye they have to be in “more aligned” than with a shorter barrel.
What is the optimal barrel length for 223?
223 Rem do best with a 16″ barrel and 1:8 twist rate. For . 308 and 7.62 NATO, a 20″ barrel and 1:12 twist rate works best for all loads. For all 300 BLK loads, a barrel measuring 9″ to 11.5″ provides optimal velocity.
What size barrels do special forces use?
Barrel lengths vary from 9 to 20 in. Firing the standard NATO M855 5.56mm bullet, muzzle velocities vary from 2400 fps (9-in.

Is a 16 inch barrel good enough?
A 16″ mid-length barrel is one of the best compromises out there for AR barrels, but it is still a compromise like most choices in barrels. My two 16″ builds are handy as hell, but I shoot both 18″ builds better. A brake on a 16″ puts a good bit of concussion towards the shooter as well; learned that with the build I did for my lady.
Can you run gas systems on an 18 inch barrel?
You can run longer gas systems on 18″ barrels to lengthen the recoil pulse while getting a modest velocity increase, but comes at a cost of weight (taper dependent) and size. I have two 18″ – One MK12 from Centurion and one Noveske 18″ LW self build.
What’s the difference between a 16 inch and an 18 inch M16?
Between 16″ and 18″ trajectory difference won’t be meaningful until 400 yards. Your second gun, try someone’s 18″ and see if you like it. They are much more noticeably front heavy. Note that the 20″ bbl original M16’s had pencil barrels and light handguards.
