Will's Review of A3 Industries Hda3 Hybrid Polymer Sig Mcx/Rattler, Folding Rifle Stock

This is a great improvement over the minimalist stock that came with my Spear LT. Highly recommend. Only reason I am not giving 5 stars is because the incorrect adapter was provided requiring me to directly reach out to A3 Industries to get what I needed.
Pros:
  • Solid well built
  • Great Adjustment features
  • storage ability
  • Better than a standard AR stock
Cons:
  • premium pricing
Would Recommend: Yes
