LIMA SIX BELT FED UPPER RECEIVER

We aren’t just about being the cheapest on the block. Here is what sets the LIMA SIX apart from the competition:

• Made in the USA
• 23% more bolt carrier travel than an AR15 (Patent Pending)
• Available as either a complete upper receiver 
• Fully customizable
• Lower perceived recoil and increased controllability
• Increased reliability stripping rounds from links
• Dual ejectors for increased reliability and parts life
• Parts compatibility with many AR15 parts:
  • Barrel
  • Extractor, Ejector, and associated springs
  • Cam Pin
  • Gas Block, Gas Tube, and Gas Key
  • Handguard (compatible with many designs)

ALL ORDERS ARE BACKORDERED 2 TO 4 WEEK LEAD TIME.

The Lima Six belt fed upper receiver WILL NOT FUNCTION with a standard AR15 buffer setup. This is because the Lima Six has a stretched upper receiver, which requires more room in the buffer tube to cycle. There are two options for buffer configurations that work:

1. A shorter buffer (AR10 length, 2.5″ long) in a standard 7″ carbine length tube (SEMI AUTO ONLY)
2. A standard buffer (AR15 length, 3.125″ long) in a longer A5 7.75″ length tube (required for full auto)

This upgrade kit contains what you need for OPTION 2. It includes an A5 buffer tube, H3 buffer, and Sprinco Orange spring.

These are commercially available parts that can either be purchased from us, or sourced anywhere else. We are simply offering these items for convenience.
