Or we'd fit our barrels to a competitor's upper receiver, and groups would open up. By making our own parts we feel confident there aren't any weak links. All The Right Stuff Let's talk about those components. The upper and lower receivers are matched during production to ensure a precise fit. On the Super Varmint rifle, there was virtually no discernible play between the two parts.
Uppers are available with or without the forward assist.
All uppers come with a Picatinney rail top for flexibility in attaching iron or optical sights. The bolt carrier, bolt carrier key, bolt and extractor are LBC precision parts, hard chromed for maximum durability. Standard equipment on Super Varmint rifles is an LBC round, free-floated handguard machined from aluminum, knurled for sure gripping and hard anodized. An optional feature is a new LBC four-position handguard. Like the original, this is a free-floating design that places no stress on the barrel.
