What is an H bar barrel?

HBAR stands for heavy barrel, or heavy barrel automatic rifle. This type of barrel has a consistent heavier barrel wall thickness than standard issue, and is a common upgrade for AR15 type rifles.

Can you use a rifle length gas system on a 16-inch barrel?

The longer rifle length gas system on a 16″ barrel will generally run most 5.56 ammuntion, as the 5.56 is a higher pressure as compared to . 223 which has less pressure.

What is the optimal barrel length for an AR-15?

If you’re looking to make accurate shots in excess of 400 meters, a barrel length of 20 inches or longer is a good way to ensure that velocity is maintained and that the bullet remains stabilized and supersonic for as long as possible. The other benefit that a barrel of this length offers is an increased sight radius.

What does H Bar mean on AR-15?

heavy barrel
The term “HBAR” means that the rifle is equipped with a heavy barrel. A heavy barrel adds a lot of weight to the rifle but a rifle thus equipped is more accurate than a rifle with a normal barrel because a heavy barrel heats up much more slowly than a normal barrel. Heat is the number one enemy of accuracy.

Why are AR barrels heavy?

Heavy barrel rifles are easier to shoot offhand. The heavier the rifle the easier it is to get it to settle down offhand. Lead weight is even addded to AR15s for target shooting to aid in this. A thicker barrel heats up slower and you can fire more rounds before the point of impact changes.

Which is better mid length or carbine?

Since carbine- and mid-length gas systems measure similarly, bear in mind that you’ll get better operation when the barrel length is closer to the middle of the functional range — a mid-length setup will better serve an 18-inch barrel than the carbine variety.

How long should a 5.56 barrel be?

Most AR-15s use a 16” Barrel. Basically, going any longer than 16” gives a negligible increase in bullet velocity, and a longer barrel is only needed if you’re trying to max out the potential distance of the 5.56 or . 223 cartridge.

What does Socom barrel mean?

SOCOM Barrel. Credit: bravocompanyusa.com. The SOCOM barrel is basically an M4/A2 in reverse. The barrel is thinner past the gas block and thicker from the chamber to the gas block, and with a cutout for mounting an M203 grenade launcher.
