Does anyone have a Burris 332 or 536 on their Sig M400 and do you have any feedback on your experience? Thanks, Brian

Hello Fam. I'm wondering if anyone out there has ever installed the JP Free Float JPHG-4M on a Sig M400 w/ Classic handguard. This handguard - JP Rifles I am just getting situated buying my AR tools and vise block... I want to know what's involved with that removal and install. Thanks in...

Just wanted to introduce myself to the forum. Proud owner of a brand new Sig M400 (the Classic model) I have a Rem 870 12, but this is my first AR/Sport rifle. I had the opportunity to shoot my friends M&P before making a decision and I must say very happy w/ the Sig M400. Can't wait to break...
