Most Helpful Positive Review Sig 556 break
What can i say that hasnt been said before about optics planet, they beat anyone’s price, think i got it from them for $45 bucks everyone else sells it for �$80 lol, it was here in 3 days, great short sig suppressor ready. this isn’t the only time they’ve hooked me up, they gave me a bfs trigger for $320, customer service is awesome, they always hook me up, I love these guys! Never had a bad experience with these guys for the last 8 years I’ve been ordering from them!

Good Quality

by Joe, from TX, United States Written on May 26, 2020
I am pleased with the product so far. Functions flawlessly and makes switching between guns much easier. Will likely be buying another one soon. Not terribly pleased with optics planet though, was notified it was on backorder after purchase and was then told a timeframe that was excessively exceeded. Tried to contact multiple times with no response. Even tried to cancel only to get a notification weeks later that it was being shipped. Oh and this was all prior to Covid. Have had great experience with them in the past, was really disappointed in this experience.

QD Adaptor

by Dog Faced Pony Soldier, from FL, United States Written on April 5, 2020
I’ve owned the 556 QD Suppressor for 2+ years. Obviously every 5.56 rifle needs a muzzle brake to use the suppressor. Easy installation, and is preferred over the adaptor that Sig sent with the suppressor. It’s an open faced adaptor with zero brake - without the suppressor, it’s like shooting with no muzzle device at all. Highly recommend this over the shipped with adaptor.
Pros:
  • easy to install
  • well constructed and light weight
Cons:
  • Could always cost less.
