Something Badass

Barrel was made by the guy who makes JP barrels and the gun was assembled by Custom order arms of Dalton Georgia.

The red thing under the hand guards is a heat sink.

Mr. High roller. Looks good. Range report!!

I know what a heat sink is...but what purpose does it serve on a gun?

Beats me but it looks cool.

The guy who built it took it out to test fire it and with cheap 147 grain ammo it shot one hole at 100 yards. I will take it out monday or some time next week and test it with 168 BTHP match ammo.

One shot, one hole? Seems legit.

Let's see your skill with both cheap and good stuff. Say, 300 yds

Lol....perfect answer

I haven't got a place to shoot at 300 nowadays. I shot 40 out of 40 in the military though so my skill isn't bad at 300 with iron sights.

Misleading thread title is misleading.





Haha, just kidding bro. Sweet setup.

Sweet.

I was curious so I Google it....

"Thermal Dissipator™

When it comes to transferring heat from your barrel, the JP Thermal Dissipator™ far exceeds traditional fluting and is intended for applications where sustained fire with excessive heat buildup is a problem, such as varmint rifles under hours of constant use.

Tests show that most heat resulting from sustained fire is developed in a 2- to 3-inch area in front of the chamber causing throat erosion and reduced accuracy over time, not to mention the problem of heat buildup in the hand guard itself that makes handling of the rifle difficult or impossible. Attaching this heat sink between the gas block and receiver will yield unparalleled heat dissipation by increasing the surface area under the hand guard by over 700% and providing more uniform barrel temperature under sustained fire.

The JP Thermal Dissipator™ is an anodized, deep-finned 6061 extruded 2-piece sleeve available in black, silver, red or blue, giving a dynamic appearance when installed under a JP high-grade hand guard.

A great upgrade for any JP rifle, upper assembly or barrel kit, this part fits any of our current production JP Supermatch barrels and can also be used on any barrel recontoured to .650" or .750" under the hand guard. Click below to see the dimensions of the individual models to determine if they will fit your barrel."

So for most intents and purposes...it looks cool

Basically, lol

Beats me but it looks cool.

Also...it sheds heat from the barrel into your hand, which is what you want.

It does look cool though.

Dude, this is how I want to build a 308 AR. Do PM me if you ever decide to sell this thing.

 

[Wallace]

Do you have any other build specs? Trigger, BCG, etc...?

 

[NWS]

5 bucks says it doesn't work.
