1. What you need:
✅ Torque wrench
✅ Blue thread stop
✅ Level
✅ Degreaser
2. Preparation:
Find out the maximum tightening torque for the optics and monoblock in Nm or in/lbs (see the description of the optics and monoblock)
Find the bolt tightening diagram for this monoblock (see the description of the monoblock).
Our recommendation:

⚡ Degrease ALL bolts and threaded holes of the monoblock.
⚡ Degrease all contact surfaces – optics and monoblock, monoblock and picatinny.
3. Installation:
👉 Set the rifle to the level: level on the picatinny.
👉 Place the monoblock with the upper half rings removed on the picatinny.
👉 Apply blue threadlocker to the bolts securing the monoblock to the picatinny rail.
👉 Grab the bolts securing the monoblock to the picatinny rail by hand (so that it does not dangle).
👉 Check the level on the rings.
👉 Place the optics CENTRALLY between the half rings (symmetrically between the rings).
👉 Place the upper half rings.
👉 Insert the bolts into the threaded holes of the half rings, having previously dropped a SMALL drop of blue threadlocker on them.
👉 Screw in all the bolts by hand to the FIRST stop and MANDATORYLY controlling the SYMMETRICITY OF THE GAPS on both sides.
👉 Since the bolts are not yet tightened, the optics should still rotate – set the optics level relative to the rings: Place a level on the optics drum and a level on the ring.
👉 Checking the gaps on both sides, tighten the bolts ACCORDING TO THE DIAGRAM and TAKING INTO ACCOUNT the maximum TIGHTENING TORQUE for OPTICS with a torque wrench!!!
⚡ Do not overtighten the optics!!!! ⚡
👉 Loosen the bolts securing the monoblock to the picatinny rail.
👉 Pressing the monoblock FORWARD, tighten the bolts securing the monoblock to the picatinny rail ACCORDING TO THE DIAGRAM and TAKING INTO ACCOUNT the maximum TIGHTENING TORQUE with a torque wrench.
⛔ In no case CAN YOU use any SEALANTS, GLUE and other hu@tu in installing optics: Shoot such masters in the knee!
4. Check:
⚡ Symmetry of the optics installation between the rings.
⚡ Symmetry of the gaps on both sides of the half rings.
⚡ The level of the optics relative to the barrel (since the optics during shooting should ALWAYS be level with the surrounding world, and not with the barrel, this is not so critical).
📢 If you have optics installed somewhere “in the workshop” and the first two symmetry criteria are not met – feel free to beat your face!!!
Happy hunting, Gentlemen!
