The LIMA SIX WILL NOT FUNCTION with a standard AR15 buffer setup. For more information about buffers, click here: https://limasix.com/product/buffer-upgrade-kit-for-lima-six/
The LIMA SIX features a patent-pending stretched upper receiver, which provides an additional ~3/4″ of bolt carrier group travel compared to a standard AR15. This is a critical improvement for a belt fed firearm, as this additional travel assists in delinking rounds from the belt, which results in more reliable feeding. It also lowers the perceived recoil and delivers a more controllable rate of fire. No other belt fed AR15 on the market has this upgrade!
Additionally, the LIMA SIX features a top cover unlike any other belt fed available. With user-adjustable tension on the hinge, two-point latch engagement, and an adjustable set-screw to take up any slack that may develop over time, The LIMA SIX has an extremely reliable ability to hold zero even after repeated opening and closing. Initial testing shows that sub 2-MOA accuracy is achievable, which is unheard of for a belt fed firearm.
The LIMA SIX is compatible with standard AR15 barrels (with simple modification), although certain factors like barrel length, profile and gas system length need to be considered before swapping barrels. Please refer to the Tech Info section of our website for complete information regarding acceptable barrels.
