Saiga Euro Grip - FAQ

Is it safe to run my Saiga on HPA?

So long as you run around 100-120psi, it should be fine. Green gas typically runs around 130psi at room temperature, and lower PSI (<80psi) is likely to cause issues if the Saiga has weak cycling. You should still expect HPA to cause more wear and tear on the replica, especially since you’ll be running more rounds through it. Inspect and maintain all moving parts and seals at regular intervals.

Most issues with the Saiga on HPA revolve around having poor feeding, which is usually caused by either weak magazine springs or using poor-quality BBs. It’s highly recommended to use PTS EPMs (150rd) or magazines fitted with Maple Superfeed springs.

What Joules can I expect with HPA?

  • Tokyo Marui Saiga 12K: .6-.8J [100-120psi (CAT5)]

  • Tokyo Marui Saiga SBS: 1-1.2J [100-120psi (CAT5)]

Joules and cycling are very dependent on the refresh rate of the regulator you use. You may find yourself using higher PSI with regulators like the Polarstar MR2 or lower PSI with regulators like the Redline Mini SFR.

Do clone MR2 regulators work?

We’ve found that most of them work. It’s important to inspect all components and verify that all seals are good and the components are machined to tolerance. It’s highly recommended to disassemble, remove the factory oil, and regrease them with TechT. There are a few that have been more reliable than actual Polarstar MR2’s due to the more robust Body ID o-ring, but we would still recommend using the real thing. 

Why is my regulator spinning?

Although this happens most commonly with the Polarstar MR2, the CAT5 is also prone to this. Usually, the setscrews haven’t dug into the body of the regulator enough, or they have backed out. 

For the CAT5, tightening the set screws should be sufficient. 

For the Polarstar MR2, it’s recommended to swap the cone-type #4-40 x 3/32” setscrew for cup-type or, even better, knurled cup-type. 

For clone MR2s, it’s recommended to swap the flat-type M3x4 setscrew for cup-type or, even better, knurled cup-type.

If you purchase a clone MR2 from us, we’ve already QC checked, relubed, drilled divots into the regulator body, replaced setscrews, and installed stainless steel thread inserts to mitigate any issues. It is recommended to avoid bottoming out your tank to prevent the regulators from locking together and to lubricate your tank O-rings with PTFE grease.
