How about a 10.5" Noveske NM Chrome lined 1/7 with Syrac adjustable gas block and a 9" UTG Super Slim handguard, forged upper and a SMI Ceramic BCG?
Less than 200 rounds down the barrel, mostly range time, never over heated or abused.
As shown, minus MagPul sights.
Over 800.00 invested in barrel/BCG/gas block/gas tube.
Quite accurate for a short barrel and runs well with a PWS pistol buffer assembly.
