SLR Sentry 7 Adjustable Gas Block

[Klem]

Has anyone had any experience/advice with this adjustable block, or any view about adjustable blocks in general?

The Sentry 7 looks like a more recent Gen 2 version of their orignal DA-7.

Klem,
I recently put one on my 16" upper. Here is my post with some info

I just put one on my Lilja. Easy install, adjustments are very simple, 5 clicks from closed allows me to run factory A-max's or SST's. The blue finish in the picture is the titanium. It isn't blue to the naked eye, it only appears that way in the photo.
I'm Happy with it.

I used the DA-7 on last couple of builds. If they hadn't just come out with that Sentry 7 I'd say I'd never use another gas block. The next gas block I buy will be the Sentry.

Thanks guys, and I had a read of your thread PA...all good.

I have a DA7 yet to be fitted and am looking at the new Sentry's now worrying (as an AR snob does) about the older one.

When you tune your adjustable blocks to being 'just reliable' are you using a standard weight buffer or heavier?

5 clicks on my 16.88" Lilja barrel. Standard Rifle buffer. 4 clicks will short cycle about half a mag's worth. 5 is just about right. 6 clicks gives severe case head swipes.

I have used standard and heavy buffer on 2 separate rifles...it doesn't make too much of a difference...your gonna tune for that setup anyway when u adjust the block. You'll be fine with a standard buffer...or even an he if u choose..u may use a click less on the block
