On a SWAT 556 with the Sig aluminum quad rail. I would like to convert it to a Classic. Are there instructions on how to remove the rails from the upper receiver/barrel? Does the gas block stay the same? I will need to get a set of classic handguards and an upper receiver top rail, right?

I've had numerous Sig's over the years and just bought my first 556. It's a swat pistol, got it used for a little over $700. So far I've swapped the forward takedown screw for a KNS push pin, Griffin angled charging handle and MI front and rear folding sight. Is there anything else that I should...

I'm selling an unused genuine Swiss adjustable black folding stock. The stock has Swiss button hardware installed. I'm also including a DDLES button designed for US-made aluminum lowers as well. Sorry, no pin with this one. Asking $375 shipped.

Up for sale is my spare SIG 556 lower. Low miles. Has all parts. I kept it as a backup as spare parts are hard to find nowadays. Asking $500. Make me an offer if you think that's too high. This is a non FFL lower. Ships in a USPS medium flat rate box. You cover shipping. Thanks, Mike Sent...

$240 shipped USPS Priority. Last one I have, thanks…P Sent from my iPhone using Tapatalk
