Introducing the Precision Rifle Suppressor Shield (PRSS)
The PRSS is the ultimate suppressor cover for bolt action precision rifles where the length of the forend or chassis does not allow an M-RAC or U-RAC to be used. Similar to our RAC series of shields, the PRSS clamps to the barrel and free floats over the suppressor mitigating the chance of incidental burns and eliminating mirage. The PRSS will use an M-RAC style coupler, and will be cross-compatible with all M-RAC & U-RAC 3.0 / 3.1 shields.
Length Measurement
The PRSS is only compatible with suppressors 1.7″ and smaller for now. XL Diameter (suppressors up to 1.9″) will be available in March 2024
To select the correct length, measure the length of your suppressor including the locking ring, and add 0.6″ (5/8″) excluding any brakes, or vented end caps, This allows your suppressor to be completely covered by carbon fiber, to completely eliminate mirage.
Example:
For a TBAC Ultra 7, your measurement will be 7″ + .6″ = 7.6″
You may choose a 7.5″ with end cap, or 8″ for full coverage of the suppressor.
*End Caps add 1.25″ (1/8″) to the nominal length of the shield. So, a 7.5″ shield will be 7.625″ with an end cap.
*As long as your barrel diameter does not exceed the diameter where you measure (below) you may slide your PRSS clamp forward and rearward to get a flush fit with the end of the suppressor.
Barrel Diameter Measurement
The PRSS is designed to accommodate a range of barrel diameters in .050″ ranges.
In order to select the proper measurement, you will need a set of calipers, or micrometer.
With a tape measure, Mark a line 1.5″ behind the muzzle shoulder or the rearward most point of your muzzle brake/suppressor.
At this mark, measure the diameter of your barrel.
PRSS Hardware is marked with the Top number of the range it will fit.
1. .700″- .750″ = .750”
2. .751″ – .800″ = .800”
3. .801″-.850″ = .850”
4. .851″-.900″ = .900”
5. .901″ – .950″ = .950”
6. .951″ – 1.000″ = 1.000”
At this time, MODTAC does not offer mounting hardware for barrels larger than 1.00″ in diameter.

Will this Affect Harmonics or give me a POI shift?
NO, after thorough testing the PRSS has proven not to change your zero or point of impact at all.
While eliminating mirage, over 90% of our test groups were smaller with the shield installed on the gun, then with just the suppressor and no shield.
Just as you would zero with a suppressor, and keep it on your gun, once your gun is zeroed with the PRSS, it will not have any negative affect on your accuracy.
As with all muzzle attachments, we recommend confirming zero after your PRSS is installed.
Why should I get the PRSS?
The PRSS is MODTAC’s newest shield, and offers a significant upgrade to using Direct Attach Shields on bolt action rifles. with the addition of the PRSS, you’ll be able to mount the shield directly to your barrel, and maintain the free-floating shield, to reduce the exposed temperature and eliminating mirage for good!
What Makes modtac shields unique
All MODTAC Suppressor Shields are designed to be free floating over the suppressor, with an air gap between the source of heat (your hot suppressor) and the inside of the shield. This lets your suppressor breathe and cool down quicker.
Are suppressor shields different than suppressor wraps?
Yes, Suppressor Shields are a rail/barrel mounted, rigid, and free floating design which does not retain heat inside of the suppressor, unlike a suppressor wrap. Additionally, there is no fabric in the our products that can come loose under pressure or melt to your rifle or suppressor.
