quadrail

Hi everyone. I am new to the forum and have just ordered my second Sig. Have owned a p238 for CC going on several years and have loved it. I have been in the market for a new AR and decided on the M400 Enhanced with ODG furniture. Pretty excited...should be here in a couple weeks. I do want to...

Sorry if this has been discussed before. This is my first post. I've decided to convert my P516 into an SBR. (don't worry. I'll complete the Form 1) After adding a stock, I'd like to add a Sig silencer, when they finally ship. I guess the issue that I'm having is finding a new quad rail...

must be lnib please. I also have a lnib 556 classic Sig Factory quad rail...taken off a new 556 classic swat when I put on swiss handguards....perfect condition...pics on request. can trade for plastic guards plus cash or sell outright. thanks
