AR 10 Type .243 & .308 Win Barrels

We are offering an AR10 type barrel chambered for the .243 & .308 Winchester cartridge. These are available in three styles and all are completely finished drop-in type barrels. They are finish-chambered and have the barrel extension installed and gas port hole drilled for a rifle-length gas system. They also are threaded 5/8" - 24 at the muzzle.

The shorter barrel in the image is our AR10740 contour, very similar to our AR740 contour in our .223 barrels. The overall length including the extension is 20". Gas block size is .750". The diameter in front of the barrel extension is 1.200" and then the profile drops down to .750" and then up to a shoulder for the .750" diameter gas block section and then down to .740" to the muzzle. Muzzle threads are 5/8 - 24. The weight is 2.70 pounds in .243 caliber and 2.58 pounds in .308 Winchester.

The other two barrels shown are our AR1024 contour, also very similar to our .223 AR24 contour. The overall length is 24". Gas block size is .936". The diameter in front of the barrel extension is 1.200, then .975" diameter to the gas block and then .875" diameter from the gas block to the muzzle. The unfluted barrel is 4.25 pounds and the fluted version is 3.90 pounds. Muzzle threads are 5/8" - 24.

All versions of this stainless steel AR10 barrel are chambered with a PTG semi-auto match reamer. They are rifled with an 11" twist 3-groove configuration in .308 Winchester and an 8" twist 3-groove in .243 Winchester. These barrels are also hand-lapped to our internal finish standards. The section forward of the gas block section is engraved: "Lilja AR .308 Win. 11T or Lilja AR .243 Win. 8T"
