We just spoke with ATF, we are actually using their table to write this.... This is an easy fix to the problem according to Rick Vasquez from Tech Branch. If you have a saiga of any kind, from any importer, you need to measure the barrel and fix it.
Measure the barrel from the bolt face closed to the end of the barrel with the choke off.
IF you have a gun that is out of spec, call your local plumber and have him silver solder it on, or weld it in place. Do not call the ATF and freak out about it. Do not call your local PD and freak out about it. Just fix it. The ATF is not as concerned about the violations on the holders end, they just want them fixed. We are dealing with the import and sales violations now. That is what they are concerned about.
IF you have a gun that is out of spec, regardless of who you got it from or when you got it, please email it to us ( firstname.lastname@example.org) or call it in to us so we can compile it for the Russian plant and address the quality control issue. Please do not waste your time or ours by posting the number here
IF you have a gun that is out of spec and got it from us we will make it right. We do not yet know how, we are working with RAAC on that. If you have a gun in question and want the removeable choke, we will exchange the gun for you. Please contact us directly for this.
We all have seen how the ATF operates, and how things can change in the agency. This is what they are saying today, so take advantage of it and do what you need to do and we can address things on our end once everyone is clear of any issues. The ATF will be addressing this in writing very shortly, so again, do what you have to do RIGHT NOW. If you choose to wait for any other kind of resolution, more than likely it will become YOUR problem. Again, if you fix it now we will do what we can to fix your problem once everyone is clear.
