Excellent nail driver

by Dan, Verified Owner from FL, United States Written on February 4, 2022
Swapped out the 4.5" on my MPX K. This is a quality upgrade giving your hand a little more room to spread out on a longer handguard. I don't plan to suppress and this thing is is a naildriver.

If you can find one, get it

Outstanding

by Kmh, from AZ, United States Written on October 9, 2019
Quality Sig part, easy swap with 16” PCC barrel. Bought it, along with a Midwest industries handguard, to convert a PCC to an SBR, works flawlessly. No appreciable loss in accuracy due to the shorter barrel and still runs smooth
Pros:
  • accuracy
  • Easy swap
Cons:
  • price
Best Used for:
  • SBR
