What owners report

  • An owner of a SIG Rattler, a short PDW with a suppressor and a telescoping stock, also fits his after some adjusting. He measured the stock support's slot at 2¼ in, so check a wide stock against that.

Snug fit for my pdw

For context i have an sig rattler with a can and a telescoping stock , it was a snug fit and took a bit of adjusting to get it to fit but was able to do it. It would have been a bit easier of a fit if the but stock portion was more adjustable for stocks that my be wider or have thicker sections. In mine with the telescoping stock the top where the rails attach is wider and stick out and was not able to fit within the given space of the slot. Do advise if u have a thicker stock or padding to measure and make sure urs will fit. For those wondering the stock slot it 2 1/4 inches. Over all I love it and it’s made well .

Questions

Which RACT version fits the SIG Sauer MPX?
The AR / Tactical Shotgun kit: the standard hinge and the AR-style trigger cover, which leaves room for the pistol grip. RACT Biometric ships with it; on RACT Keypad, choose the AR / Tactical Shotgun version.
What if my SIG Sauer MPX is set up differently?
Every part of RACT slides along the rail, so the barrel lock, trigger cover and stock support move to suit your gun's length, scope, light and sling. If your build differs from the owners' here, email support@varasafety.com with the make, model and what is mounted, and we will confirm before you order.
