Re: new HOT Topic LWRC or POF in .223??
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: kimberseries1</div><div class="ubbcode-body">I'd go with LWRC for their coatings. Bore coating extends barrel life to 20,000 rds. says them. Their Ceracote finish on the gun is nice too (FDE, OD, BLK). BCG coated with their Nicoat or whatever, drylube, plus all lower components are coated with Nicoat or whatever.
Haven't hefted or shot a POF, so I'm not dissin' 'em, but LWRC is where I'd go for a piston. </div></div>
POF uses coating on their stuff too and makes the extended life claims also.

<div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body"> We are the first gas piston operated weapon system on the AR-style rifle platform to sell to the market. All of our weapon systems come standard using C.R.O.S.™ (Corrosion Resistant Operating System), which allows our weapon system to operate without the need of lubricant.
Our fluted barrels using NATO chambers are polygonal rifled, using 4150 Mil-B-11595 chrome-moly vanadium alloy (machine gun rated), to reduce heat and weight. All of our barrels are 70 rockwell case hardened heat treated which are corrosion resistant, and 2X harder then Mil-Spec and hammer forged barrels.
Our heat sink barrel nuts, fluted barrels, and free floating rail design help to reduce heat of the barrel around the chamber throat area of the barrel and the overall operating temperature of the weapon system.
Nitrate heat treated barrel:
20” heavy contour, hand-lapped button twisted rifled, fluted to reduce
weight and heat
4150 Mil-B-11595 chrome-moly-vanadium alloy (machine gun rated)
70 Rockwell case hardened (Nitrate ) heat treated “5R” polygonal
barrels are 2 times harder than Mil-Spec & hammer forged barrels
Corrosion resistant and 10 times thicker and harder than Mil-Spec chrome lining

Roller cam pin NP3™ coated
Chrome plated bolt, heat treated to Mil-Spec

I've seen the 20,000 round barrel life claims I just can't remember where.
I only have experience with my 20" P308 so I can't tell you which is better. I do really like my rifle though.
