needmoneyforgunsSig MCX Virtus (gen 2) bolt carrier group and recoil spring assembly. Brand new (opened) but never used. I bought a bunch of parts for my MCX but will never need them since I ended up buying tons of guns so I barely use it :) Comes assembled as is from sig. bolt, bcg, firing pin, recoil assembly, etc all included. Sig website selling them for $650, but they are often out of stock. Will work in a spear LT if you use an MCX trigger.
