Rokin Precision parts for the Grand Power Stribog, designed and tested in small batches by an engineer who shoots. First up: a 35 degree locking block for suppressed shooting.
35 Degree Locking Block for the SP9A3 and A3S
The standard US-spec Stribog uses a 45 degree locking block. Our 35 degree block changes how the bolt unlocks, to cut down the recoil and the gas you feel when you shoot with a suppressor on. We dialed it in on our own SP9A3 with an Exigent Rico 309, testing with 147 gr and 165 gr loads.
- Fits: Stribog SP9A3 and A3S
- Material: 4140 steel, matched to the hardness of the US-spec 45 degree block
- Finish: black oxide (some areas polish off with use, and that’s normal)
- Install: no tools. See the step-by-step photo install guide.
