- 12.5" Rosco Lightweight - $75
3 - Location (Henderson)
In Henderson. Meet at GVR, RC Willey/WinCo, The M, , Sam's Town, Costco St. Rose, Bass Pro, RC Willey Summerlin, Best Buy lot @Charleston/215. Not really looking for trades at the moment but would consider partial trade for one or more of the 223/556 ammo types listed in my other thread.
"I'll take it" rules apply and override PMs in process. My usual disclaimer: Weekday availability M-Th is terrible (~530P-730P, or 'lunch' meets near me). Fri/Sat/Sun 'most' daylight hours (events creep in so availability changes).
All of the below barrels were purchased for evaluation / testing purposes and are very lightly used (tested through a battery of ammo batches then pulled). If you've been around for a bit, you've likely seen some of my barrel (and ammo) evals posted. I've got a small pile of 12.5" eval'd barrels in my workshop and with the $200 NFA tax gone the way of the dodo, anyone looking to make their own 12.5" SBR now is good time.
Accurate round count is posted with each barrel listed.
Centurion Arms 12.5" 'Lightweight' Hammer Forged 5.56 barrel - Very lightly used - $195
From the manufacturer:
Some of the most accurate, well gassed, and durable barrels out of the box for your AR Platform Rifle. The Centurion Hammer Forged Series of barrels are designed to withstand very high round count shooting whilst maintaining excellent accuracy. Centurion barrels also feature a very intuitive notch behind the gas block, which mates with their notched gas block ensuring proper alignment during installation and use. (Any standard un-notched gas block will also work)

Rainier Arms Mountain MOD2 12.5" barrel - Very lightly used - $195
From the manufacturer:
Allow us to reintroduce ourselves. We have brought back our Mountain Series of barrels for those of you who want the accuracy you expect from Rainier Arms in a nearly indestructible package. These barrels are made out of 4150 CMV and nitrided as well. That means these barrels will take anything you can throw at them. They are meant to be shot, and shot a lot. The half-fluted profile maximizes heat dissipation and helps reduce weight.
Rainier barrels are meticulously designed and machined by precision gunsmiths. Our barrels are turned the same way true artisans have made premium rifle barrels for over a century. Each barrel has hand-cut chambers and crowns with the attention to detail that can only come from highly trained human intervention. While most companies strive for faster production time to cut costs, we strive for perfection. There are no shortcuts with our barrels, period. We will go toe to toe with anyone and win.

Rosco (Brownells) Lightweight .223 Wylde 12.5" barrel - Very lightly used - $75
From the manufacturer:
Rosco/Brownells Lightweight Carbine Barrels come in a variety of popular lengths, ready to suite any new carbine build. Manufactured to Brownells specifications by Rosco Manufacturing, the button rifled barrels, profiled from 4150 Chrome Moly Vanadium steel, feature a 223 Wylde chamber, that allows them to accommodate 223 Remington and 5.56x45mm NATO ammunition equally well. The 1-8 twist will handle commonly available Full Metal Jacket 55gr loads, all the way up to heavier, premium 77gr bullets. All of these Lightweight Barrels have a .625 gas block journal to correspond with the overall slim profile, preventing your Carbine from becoming front heavy.½-28 muzzle threads accept common muzzle devices and the M4 feed ramps at the opposite end interface perfectly with M4 feed ramps in your upper receiver. The durable Nitride finish prevents corrosion, eases cleaning and has an extra hard surface to prevent dings and nicks.
