Extremely well made, perfect fit, works well, comes with long 2mm hex wrench to adjust at the front. You will want to buy a $30 dimpling jig that has .400" hole spacing, like the Kak or SLR.

A Must Have
Great product. Fit, finish, and function is excellent. I don't build anything without the ability to adjust the gas for optimum performance and this has become my go to gas block. RTB offers SLR gas blocks for the best prices around and with the addition of either a gas tube or extra discount, this is a no brainer.

Works great on my Lothar walther barrel
So far so good. Nice and snug fit, adjustments are easy to find and firm. Works extremely well with my Surefire SOCOM, and it really cuts down on overgassing. Rifle shoots much smoother now

A+
I have used this exact model of gas block on my last three builds. I haven't played around with many others, and I don't feel the need to. These work perfectly for me all the time, whether on my 7.5" pistol, my 16" mid-length, or my 18" rifle-length. I placed my order with RTB, gas block shipped within 24 hrs, and the post office got it to me in two days. I don't know what else to say, if you are looking for a gas block like this one you've come to the right place. The price is right, service from RTB was excellent, and this piece of gear is top-notch.

A must have for any AR build
This SLR adjustable gas block is worth every penny. Made dialing in my new 9" 300 BLK BA barrel a snap. Setting six works best for 123gr Magtech and setting 12 works for the 220gr sub sonic rounds. Setting 12 also works for the 123gr Magtech, albeit with a little more pep. Easy to install. Get the long 2mm adjustment driver from Amazon to reach into the handguard with ease.

Great as Always
I have 3 now and all work perfectly. One Pro tip, go to full open, to full close, then back to your exact setting every 200-500 rounds so it doesn't lock up. Physically impossible for a adjustable gas block to not lock up if you fire enough rounds through it. Oh and the best place to buy is Right to Bear. They had my parts to me in 2 days and they were back logged from the presidents day sale. Mind you I did not pay for fast shipping. I always check them first when shopping.

Savings
Since I didn't need a gas tube and with additional savings at checkout my Odin key-mod rail was practically free. You guys are great! Never pay list price.
