Product Questions

Is this item new or used? Will you be intrested in selling just the receiver without the stock, buffer tube and grip at a reduced price?

Referenced product: RM400-16B-ECP-LWR

This is new. We can't sell just part of it but we do have a stripped Sig M400 lower, part number LWR-M400-516-STRIPPED, typically available (currently on back order as of this response) and we've just received Sig Sauer OEM M400 parts kits which include all of the small parts for the lower (including trigger). Those will be posted on our site very soon under part number PARTSKIT-M400-SEMI.
