Syrac's a good choice. I like Glen, but I won't do his adjustable again until he changes the design. Having the adjustment on the rear of the block is a pain in the ass.

I think you shoot it as is.

The thing with cans... is they become collections in themselves.

Yeah, I am leaning towards the MicroMOA but they are out of stock :-(

Any better ideas?

Have to wait for this weekend :-( but I know the Daniel Defense barrel is over gassed. (Port of .082) so I'd like to tone it down a bit. Even before tossing the suppressor in the mix.

I hear great things about syrac but have never used them personally. I like and have used seekins precisions adj block. It works well.

My wife gets royally pissed if I even think about having any other cans around. :D

I have an SLR DA7 on my 5.56 10" upper, and a SLR Sentry on my 300BLK 8.2" upper - I like his design, a single adjustment on the front. No button to depress, and strong clicks when adjusting. Altho I hear Syrac now has a Gen2 that has a single tool adjustment.
plus I've been super happy with the service at SLR... due to user error I goofed up a DA7 and he sent me a free replacement, upgraded to the Sentry model.


Nice can BTW ;)

Congratulations! That's a nice gun! BTE has adjustable gas blocks at a very reasonable price. I just checked. You can get one of their low profile gas blocks for $35 on e-bay.

Got a free moment to hit the range and test the can... IM HOOKED! 😀

As suspected it's ejecting at 1 o'clock so I'm going to get an adjustable gas block to dial it in.

Took me a second on that last picture lol. With your build, a WAR upper is probably not an option and unfortunately I don't have experience with other gas adjustment systems to make a recommendation there.

Is it 100% necessary with that SF can? They are stronger than others when it comes to back pressure reduction etc....I Know its not feasible but seeing a different can on the same rifle (M42K, Saker etc) would be interesting. What volume of blowback were you experiencing?


I have the suppressor bug again. I want #5 so bad

Honestly I didn't notice much of any gas in the face. But the recoil impulse is definitely more. (It's 5.56, so I'm not saying it was uncomfortable, just noticeably more) and ejection pattern went from being thrown far to my 3 o'clock to barely making it off the table at the 1 o'clock position with the can on.

The rifle will pretty much live with the suppressor on, and I know I can dial it in better so I ordered the Syrac last night as the MicroMOA still has a 2+ lead time on coming in stock.

Here's hoping lol I'll keep this updated with my findings after it comes in from Rainier

Something to add for clarity...

The CQBR upper issued to the military to be used with the Surefire 556RC has a gas port size of .070 to be reliable with and without the can.

Daniel Defense enlarged theirs to .082 so it'll work with Tula ammo and such. But for me shooting 855 or 193 it's overkill and even more so when the can is added

So that's basically why I want to fiddle around with trying to dial it back some
