SBI Lynx 180 Match Review

SBI Lynx 180 Match Review

The Spectre Ballistics International (SBI) Lynx 180 Match is an AR180 compliant lower you can use to build out a competition AR180.

Lynx 180 Match Specs:

  • Very lightweight
  • Uses AR triggers, trigger pins, safeties, mag release
  • Uses non-beavertail AR grips
  • Flared mag well
  • Stock attach options:
    • Buffer tube
    • 1913 rear rail
    • Magpul Zhukov Stock (Yugo variant)
    • other mounts are about $30

What you’ll still need from your WK or WS-MCR for the lower build:

  • Bolt hold open, spring, etc

Build peculiarities:

The lower went together really easily but I found 2 things that you should watch for when doing your build:

  1. The magazine well wall is pretty thin so you should screw your mag catch in all the way. If you leave it a turn or two out, it’s possible to press the mag release too far and have the catch rotate outside of the magazine well.
  2. You may have to stretch your AR safety detent spring or use a plug to get correct engagement. Play with it until you’re happy with the force required to use the safety.
  3. The buffer tube adapter won’t fit standard end plates so you won’t be able to use your fancy QD cup end plate.
