7.5″ LO-PRO SLOPE NOSE QUAD RAIL (LPSN™)
The Phase 5™ LPSN™ was developed as an improvement to our previous quad rail. The new LPSN™ was inspired by lots of beneficial features that shooters have requested and demanded from us and other manufacturers. The slender design, longer nose, ease of installation and superior construction are some of the features that we designed into this system. Another development feature is the finish quality. The LPSN™ undergoes a rigorous extra de-burring process in order to ensure a smoother snag free finish.
PHASE 5™ 7.5″ BARREL
Phase 5 introduces the AR-type pistol barrel in 7.5”. This precision air-gauged barrel is heat-treated fully then thermo stress-relieved for optimum durability and performance. These barrels are assembled with precision ground Electroless Nickel (EN) coated extensions with Mil- Spec M4 feedramps for best performance. The 41V50 chromoly barrel provides superior corrosion resistance and durability, while the manganese phosphate finish helps prevent rust and provides visual appeal with a wide range of weapon systems.
PHASE 5™ AMBIDEXTROUS BATTLE LATCH CHARGING HANDLE ASSEMBLY (ABL/CHA™)
The Phase 5 ABL/CHA™ features a fully ambidextrous design, ideal for left or right handed operators. Broad contact points provide a sure grip and the ability to manipulate the weapon on a piece of gear or by foot. An upgraded stainless steel coiled spring and increased wall thickness make it the ideal choice for extreme situations.
