It does what its supposed to. I like the small footprint. The first one arrived with a cracked vial, both KAC and BTO offered to replace it very quickly.

these are good bubble levels and i’ve used them quite a bit. it doesn’t matter til it matters when it comes to keeping your gun level and shooting at distance

Ordered january 2022. July of 2022 looks like the bubble level lost pressure and no longer give you a reading. Customer service had me contact KAC to see if they can help. Super low profile and fit under a razor 1-6 with a 1.5 mount. Hopefully they can replace because when it worked it was nice to have.
