Ship us your upper and we will cut your barrel down, square and polish the new muzzle crown, and thread on a P90 flash hider. Your receiver will be unobtrusively stamped with “Champlin Customs Sedona AZ".
We do not recommend using a suppressor on your PS90. The increased bolt velocity damages the trigger pack and decreases reliability. The gas blow back is extreme; it fouls the mags, chamber, trigger, and bolt, and can even blow the magazine off the weapon. For this reason, we do not offer a threaded muzzle SBR. The P90 flash hider is a good unit and is the way to go.
Please understand and follow these steps:
- Prior to purchasing this service get ahold of you local FFL SOT. The SBR will be shipped to them. Do not purchase this service if there is anything prohibiting you from owning an SBR.
- After purchasing this service ship us your upper and wait patiently. Turn around time is up to 1 month. We then ship your SBR to your local FFL SOT.
- After they receive the SBR, they will help you fill out your form 4 paperwork, this is the paperwork you send to the ATF along with your $200 tax.
- Wait patiently, again. Your local FFL SOT will keep your SBR until the paperwork comes back from the ATF. Then you'll make your second trip to your FFL SOT, this time to pick up your SBR and paperwork. At some point you will have paid your FFL SOT their NFA transfer fee.
