I just picked this up last week. The Sig 556xi Russian pistol with brace. So far 300 rounds fired with no issues. I saw some bad reviews on the xi Russian but this one is great…
Congratulations, nice looking pistol. If you wanted to SBR it, is it possible to install one of the Swiss style side folding stocks?
I have used a 16" version with a folding stock. I think you can get either an AR receiver extension adapter for AR stocks, a picatinny rail back, or a side-folding stock. With the 10.5" barrel and the stock folded, it’s a fairly compact package.
That is a pretty intriguing concept. AK mags, 7.62x39, with an integral pic rail for optics. On paper it sounds great. Keep us posted on how she runs.
