This COMPLETE PARTS KIT (everything except stripped lower receiver) includes the following features as standard:

M4 Feed Ramp barrel extension
1-9" twist, 6 grooves, right hand
5.56mm chamber (shoot either 5.56mm or .223)
11595E (SAE 4150) Barrel steel
Manganese Phosphate finish barrel

This 5.56mm caliber barrel is 10.25" long, threaded the standard 1/2 x 28 tpi with an A2 flash hider and the correct crush washer. The barrel is machined from chrome-moly, high vanadium steel and hardened to a U.S. government Mil-spec of Rc 26-32. The barrel, and all external steel parts, are manganese phosphate finished IAW 5.3.1.2 of Mil-STD-171, the U. S. government's recommended protective finish for steel. This finish not only looks great, it affords complete corrosion protection. The barrel is a mid-weight contour (tapered under the handguards, .750 under the front sight base) which alleviates barrel whip and enhances accuracy in semi auto fire and helps dissipate heat. The barrel is button rifled with 6 grooves, right hand, 1 / 9 twist. The 1/9 twist is best because it handles the widest variety of ammunition and bullet weights.

The barrel is mounted on a FORGED 7073T6 Aluminum upper receiver with the proper "T" position markings, hardcoat anodized IAW Mil Spec A8625, Type III, Class II, black per No. 37038, Table IX with nickel acetate seal, as per the Mil-spec. The upper features a forward assist and hinged ejection port cover. 

This kit features an ultra slim (1.360" ID) KEYMOD handguard for a comfortable grip and easy and SECURE mounting of accessories.  It has an integral full length M1913 Picatinny top rail and rows of KEYMOD mounting slots around the handguard. This handguard is machined from aircraft aluminum and hardcoat anodized IAW Mil Spec A8625, Type III, Class II, black per No. 37038, Table IX with nickel acetate seal, as per the Mil-spec and is massively machined with KEYMOD slots for efficient cooling and maximum adaptibilty. This handguard completely free floats the barrel. 

The buffer tube contains a standard carbine buffer and spring for reliable function and is covered in a closed cell foam for shooting comfort.  This system utilizes a 4-40 set screw to retain the rear takedown spring and lock plate is not needed.  You can remoe the foam cover to easily mount a "Forearm Stabilizer" (not included) on the buffer tube if you wish.

All semi auto lower receiver parts are INCLUDED as well as semi auto bolt, carrier, and charging handle. The upper is COMPLETELY ASSEMBLED, and HEADSPACED. Each and every part to the gun is included EXCEPT the stripped lower receiver! (A complete firearm is pictured, the lower receiver and magazine, even though shown in the picture, are NOT included).

Don't forget the Mil Spec Aluminum, 30 round magazines:

PLEASE NOTE:  For CHROMED barrel interior and chamber, You must ACTUALLY Order part # AR-CHROME on your web order form, if you do not see it and it does not charge you $50 on your form, you have not ordered it and will not receive a chromed barrel. Do NOT just put it in the special instructions. Here is the link: http://blackthorneproducts.com/cart/index.php?main_page=product_info&cPath=0&products_id=300

Since this parts kit does not include the receiver, no FFL is required. Like all of our AR parts kits, this is MADE IN USA!
