Sylvan Arms

by James, Verified Owner from AZ, United States Written on July 2, 2024
I have been using this on my AR in 6.5 creedmoor for about a month. Really helps hold the muzzle down.

Sylvan Arms Competition Rifle Weights

by James, Verified Owner from AZ, United States Written on June 2, 2024
Works great . On my AR in 223 it reduced the muzzle jump at 600 yards from a little over 2 mil to 1/2 mil . The screws do need a little loc-tight or at min tighten down as one of the screws fell out.
Pros:
  • Works great
Cons:
  • tighten the screws no big deal
Would recommend: Yes

Great solution for rifles serving double duty in competition

by WeighedDown, Verified Owner from AZ, United States Written on December 16, 2023
I use 4 sets of these on my precision AR, and Sig Cross PRS/NRL rifles, for competition.

While they increase the barrel shroud/rail diameter, they seem to provide better grip points when clamping to a bag or barricade. In 1 month of use, 3 competitions, and lots of practice sessions, I haven't had one come off. The coating has held up to my abuse really well, and doesn't mar the rifles.

You can easily swap from rifle and they are the heaviest solution on the market. They also improved the balance point to just forward of the magazine well or right at an ARCA mount depending on where I place them.

One set did arrive missing some screws, then in the month I've had them, 2 screws and buttons fell off (The Sylvan team mailed some replacements right away, no charge). Use a non-permanent thread locker on the button screws to avoid the same issue.
Pros:
  • durable coating
  • Easy install/removal
  • Heaviest market weight available
  • Balance point tuning
Cons:
  • Bolts need thread locker
Best Used for:
  • Competition weight
  • Balance point tuning
Would recommend: Yes
