Size: 30mm Tube


Style: ‎Cantilever Mount, Picatinny Mount


Features

  • DISCOVERYOPT heavy-duty 30mm scope mount features Inner Bore Grinding, achieving smaller radial and coaxial errors than other models on the market. This ensures higher durability, recoil resistance, and stability, always holding zero even after repeated high-recoil firing, well-suited for powerful riflescope.
  • The 20 MOA built-in cant allows for a more available elevation adjustment range for the scope, enabling precise targeting at longer distances. Weight: 6.3ounces; Height: 1.5inch; Suitable Tube Size: 30mm.
  • The offset design offers a 2-inch forward extension for the scope positioning, ensuring optimal eye relief position. Designed for all-day comfort with minimal fatigue.
  • Crafted from 6061 aerospace aluminum, this cantilever mount offers a lightweight design while maintaining exceptional strength and durability. Secured by 12 T-20 screws, it ensures superior stability.
  • This one-piece scope mount features picatinny locking bolts and TORX screws, ensuring a solid fit on any standard picatinny rail. The base is secured with 3 TORX screws for enhanced stability and accuracy.For higher precision, the scope rings inner bore is pre-polished. As a result, slight aluminum traces may remain on the riflescope tube surface, and be impossible to wipe off, which is normal and does not affect performance.

  • No lapping necessary.
Size: 30mm Tube Style: ‎Cantilever Mount, Picatinny Mount
IMHO, all of the DISCOVERYOP scope mounts excel in quality machining, finish and appearance. The rings are factory bored in pairs for concentric alignment. No lapping necessary. Ring saddle is left bare and coated with grease to prevent corrosion. It should be noted that the 1913 attachment screw heads are on the starboard side of the weapon and require the (included) TORX wrench for installation and removal. This allows even torque pressure, but prevents quick field removal. On might consider offset back up sights or dedicate this mount to competition matches and recreational target practice. ... show more

  • Better than Monstrum!
Size: 34mm Tube Style: ‎Cantilever Mount, Picatinny Mount
bought this set as the montrum rings I bought would just not tighten up on my scope.. Perfect fit, perfect finish and super smooth contact with my scope. this is now my second set and these punch way out of their price range ... now only if these were QD. Frankly I have not looked to see if they offer a qd version ... maybe they do ... regardless these are awesome for the price and they come well packaged too! ... show more

  • Good mount
Size: 34mm Tube Style: ‎Cantilever Mount, Picatinny Mount
Mount is good quality and built well keeps scope in place with no shifting to mount. Go by scope recommendations for tightness of scope caps.

  • Quality better than expected for the price
Size: 30mm Tube Style: ‎Cantilever Mount, Picatinny Mount
Really nice quality. I was having problems with my scope sliding in the scope mount on my .308. This mount solved that problem. It is far more secure. Very impressed for the price point.

  • Seems to be a solid mount for the price.
Size: 30mm Tube Style: ‎Cantilever Mount, Picatinny Mount
The build quality seems to be good for a cheap mount and it seems very study. The rings fit perfect around the 30mm tube on the scope. I haven't had the chance to go zero the scope yet so not sure how well it'll hold the scope but I don't foresee any problems. I torqued everything to specs. Vortex recommends 18in lbs on the rings and the mount 30in lbs. ... show more
