Monstrum Rifle Scope Level Bubble

For the price, the Monstrum Rifle Scope Level Bubble is an excellent, practical accessory rugged enough for regular use, simple to mount, and accurate enough for most real-world long-range and hunting needs. If you want boutique machining or rock-solid lifetime zero performance on very high-end builds, consider premium light weight alternatives but for 90% of shooters this is a very smart buy. good for use has great stability

I have put these levels on the scopes of most of my rifles. I love their function, and they are easy to see while I'm shooting. They have been accurate so far, and they really are a must if you want to do long range shooting. When I started I didn't realize how much a very slight amount of cant can completely change your point of impact. This has helped me hit steel at 1,000 yards. I wouldn't shoot long range without one.

I usually don't write reviews when I haven't had a product longer then a year, but I was kind of surprised on the packaging I was half suspecting it to come in a cardboard package which it did technically, but it has its own little plastic box. For the price point it seems like it well made installation was easy enough.

Have purchased several of these recently in both 1” & 30mm. Great visibility & low profile. Easy to install & fits tight. As some have noted, the bottom arrow is slightly off center on my 1” levels (not a deal breaker for me) but my 30mm level is dead on. Some have also suggested loc-tite on the screw to keep it from loosening with recoil. Time will tell on that one. Otherwise a great product.

Does the job, good fit and finish. A level is important for long range shooting. This design works better than I expected, mounted in front of the turrets the level is out of the way yet can be easily seen above the parallax adjustment. Great buy for the price.

Great item definitely helps keep gun level at the range or while shooting in general

This anticant device reacts quickly, is easy to install, and is priced right. You can verify the level by viewing it from above. The bubble placement is elevated, making it easy to see, especially when you position the level in front of the turrets. I own several; they compare favorably to those of the name brands.

They are light weight but work well on my 22lr.
