Is anyone familiar with the SI Defense (now falkor) AR10 lower? I've had it for years and just saw there's a tension screw slot for the upper/lower. Im currently deployed, so trying different different sizes is not going to happen and couldn't find anything online about it. Does anyone happen to know the size of the tensioning screw?

They do the same Bullshit with their Falkor receiver sets, you have to call and request the tensioning screw.
 
Classic, thanks
So I know I’m a few months late to the party, but I also have an SI Defense 308 set that I picked up in 2013. It’s been sitting since. Decided to assemble it and am down to the tensioning screw issue myself. I emailed Falkor about getting a screw, no dice. He didn’t know the size, thread pitch and didn’t have any to give/sell Response was that(SID) was a different company. Recommended for me to take the lower down to a hardware store and figure it out. So, that’s what I’ll do, I guess.
Runnineh, were you able to find out the size of the screw? Source something that works?
Thanks

I called Falkor and had to talk to a higher up, they jerked me around as well. This is the main reason why they lost my business and support.
