Pencil Journal by Wasted Youth, Verified Owner, March 26, 2025
Ordered a 14.5 inch pencil barrel - weight 21 oz. Please note that the gas journal is 0.625 inch. The barrel is perfectly gassed - very flat shooting with H1 Buffer and standard carbine spring - 3 o'clock ejection with M193.

Great Truck Gun Option by DangerDOM, September 4, 2024
When it comes to gov profile barrels, can't beat these for the price. Have them on 2 builds and they work great, look good too. Solid choice for a truck gun.

High Quality Barrel by The Truman, September 5, 2024
I like the nitride finish, gas block dimples are a nice touch at this price point. Not that common from my experience at < $100. Barrel held surprisingly tight groups and fit in super well.

wrong description by gstock, Verified Owner, March 18, 2025
Ordered the 11.5 lead and steel barrel. Description Said it was dimpled and a 1/8 twist. The barrel did not come dimpled like it was advertised to be and it was a 1/7 twist. However quality of the actual barrel seems nice, gas port is .080 if anyone...

Product Info for Lead & Steel AR-15 5.56mm Threaded AR Barrel

Machined from a GM 4150 CMV blank, this Lead & Steel 4150 Nitride 5.56mm barrel, dimpled, is fully stress-relieved and 11 target crowned, with a gas nitride finish. The barrels are ported conservatively. Paired with a heavy buffer, you may experience stoppages with underpowered steel-cased ammo. To guarantee reliability with all ammo types, use a standard carbine buffer + spring and run the system with a magazine of full power M193/M855, if new, before shooting steel. After an initial 30rd break in, steel-cased ammo can be used without issue.image
