Syrac gas block installation

[Smithcollector]

I have a White Oak barrel on which I would like to install a Syrac adjustable block. However, the barrel diameter is taken down to 0.75" only 0.25" from the gas port. Is this enough room to install the Syrac block? In other words, how far from the back of the block is the gas hole?

The hole in the SYRAC II series starts at 7/32".

You will need a straight gas tube or you will be bending
a mil-spec tube and feeling interference when the gas key tries to mate.

The screws supplied with the SYRAC II are pot metal.

Order a box of 6-32 x 3/8 TORX PLUS SHCS and a TORX PLUS bit
from McMaster-Carr and be done with it.

Don't know where the McM-C screws come from but they can handle
the required 55-70in/lbs.

The TORX PLUS bit... mine is marked:

TORX PLUS

on one flat and 180 degrees opposite flat has

WIHA 7016
GERMANY

I own three (3) SYRAC clamp-ons 0.936".

Growth pains has caused their website to be full of shit and sometimes QC allows
a unit out that has no mating hole to the barrel's gas port... among other things. I have pics and emails.

Best to you.

I like Wilson Combat straight gas tubes. I couldn't find them on their website so I just called and received them UPS Ground in 48 hours.

EDIT: Just notice that you are in Georgia. Close enough for Dallas to get two free High Torque Screws and use my WIHA TP bit and Torque Driver?

Out of six (6) screws, I had one SYRAC supplied screw that sheered before 36in/lbs.

Thank you sir - Syrac should include a copy of your response in their literature.

I've been in Electronics Engineering/Design Grab & Fetch It for 28 years with half a dozen companies.

All of them young and hitting that growth spurt @ 18 months after I showed up as employee # 7 - 24.

I still have my three SYRACS and have no desire to go SLR or any other.

Don't get me started on what I did to my '70 Triumph GT6 MkIII or '69 Camaro...

as long as the SYRAC II has a hole to mate with the gas port, changing out two screws of higher quality and a bit made of German steel ain't all bad.

That's fucking ridiculous!! is that what the instruction state?? There is absolutely no need for that much torque..

It's the perfect da-da-damn spec with good metal when using a clamp-on gas block. Mark Westrom proved it...

just like he did with so very much of the .308/762 mechanics that ZEROX designers failed to notice: i.e. firing pin hole diameter, mid-length, yada yada

EDIT: inch/pounds are in the spec, not foot/pounds

I know you were talking in/lbs, and i still think that's crazy...IMO but anyway moving on...lol
