We were going to do an article on the LF-15C from Legion Firearms in case any of our readers wanted to buy one, but...they're all gone. They sold out the entire first production run. So never mind, unless you just want a lower…there won’t be any more complete LF-15Cs until the end of August.
The LF-15C is imported to the US from the great state of Texas. It’s a completely monolithic upper with 1/8 twist and an ambi lower, constructed of 7075-T6 aircraft grade billet aluminum alloy that’s as strong as many steels. It has a 16” ball-milled 416 stainless steel arc-rifled barrel and will, Legion assures us, spike sub-MOA groups with MK262 ammunition.
Other features of the weapon are an SSA trigger, adjustable gas block and an enhanced bolt carrier group (the latter includes a chrome-silicon cryo-treated extractor spring, viton plunger and fluorosilicone O-ring). The action spring is actually a hard chrome silicon spring rather than MILSPEC. All LF-15Cs rock a BattleComp 2.0 compensator and Noveske switchblock. (More on BattleComp in a future article, FYI.)
“Our barrels are 1 in 8 [twist], but we use a non-standard bore in a match grade three groove polygonal twist,” said Legion's Jamie Wehmeyer. “So for instance we can shoot 77 grain without loss of accuracy. We actually exceed mil-spec standards…and though it may seem like a small distinction, [the LF-15C] is chambered in 5.56mm NATO, not .223.
The entire weapon has a proprietary WMD NiBx nickel-boron coating that is “plenty smooth but more flexible…super hard coating, very lubricious…we only use lube on the gas rings and action spring…we’ve run 3,000 rounds through our prototypes without cleaning, not problem…the first prototype went over 8,000 rounds with 3 ½ cleanings—the half was just an exterior wipe-down for photo ops…” There are two coatings on the upper and lower receivers and one on the bolt carrier group. The outer coating on both receivers is a proprietary WMD ceramic hard-coat. All LF-15Cs come with a Phase 5 Tactical “Revo” sling mount (they helped with the T&E process) and an invitation to a free LCC1 Course instructed by Legion trainers.
“We ran one of our prototypes on a super hot day, 110 degrees out plus the suppressor and ran seventeen mags of XM193 as fast as we could shoot,” Legion’s Jamie Wehmeyer told us. “It ran flawlessly…" That prototype now has 11,500 rounds through it and still produces sub-MOA groups.
