The Spartan 3 sound suppressor is a lightweight, durable, compact, direct thread 5.56mm silencer.

The Spartan 3 was designed to provide the end user with a durable, compact, lightweight suppressor at an affordable price. The Spartan 3 is unique in that it is 6.25" long and comes pre-drilled for pinning and welding to barrels as short as 10.5" to achieve a suppressed SBR with only 1 tax stamp required (total length of 10.5" barrel with Spartan 3 pinned is 16.1" and NFA compliant) With this objective in mind, an optimized silencer was built. The Spartan 3 is CNC machined and TIG fusion welded for maximum thermal transfer, strength and durability. Every component in the Spartan 3 is manufactured from high strength, high temperature, corrosion resistant alloys.


For an affordable, lightweight, and durable silencer, the Spartan 3 is a perfect fit.

    excellent can for a one stamp AR

    Published by thomas russell on 6th Jul 2016

    this is my first can. pinned this onto an 11.5 midlength gas w/adj GB , very impressed with no earpro it was hearing safe, no port pop either. muzzle blast/sonic crack sounded like it was 4-5 feet in front of the can , not immediate. with earpro the shot was quite enough it allowed me to hear the operation noise of the rifle. only have 20 rounds so far through it but I am definitely pleased with this investment

    Fantastic peace of kit!

    Published by Matt Jones on 24th Jan 2016

    Had mine pinned to a spikes 10.5 upper and everything came out exactly as it was advertised. Put it on about 2 months ago and have 1,000 or 1,500 rounds threw it and it's working perfectly. Put four mags "consecutivly" threw it on full auto with no issues. Its great being able to train without ear pro. I did pick this model so I didn't have to get a tax stamp for the SBR. If you pin this to an SBR upper you save
    $200 on SBR tax stamp
    $90 on lower engraving
    $50 or$100 on paperwork from your FFL
    And it's $250 cheaper than the next model.
    Griffin armament has built a fantastic peace of kit that is at a great price point.
    Thank you griffin armament!
