WTS WA Sig MCX Parts - Virtus and Legacy

RainMan_PNW · Jun 14, 2019

I've got some Sig MCX parts up for sale...all perfect parts for someone out there with an SBR'd or pistol Legacy MCX who wants to have more flexibility!

Sig Telescoping Pistol Brace (BRACE-X-COLLAPSIBLE-BLK) - $140

Came off my Sig MPX TacOps pistol before I switched that over to a side-folding brace
Fits MPX and both Legacy and Virtus MCX, but will not fit a standard AR lower with an MCX adapter (I tested it)
"Three" position brace (fully collapsed, mid-way, and fully extended)
Sig branded, with sling loop on the bottom and round button for extending

Sig SBX brace with tube and folding knuckle (KIT-SBX-X-FOLD-BLK) - $120

Came off of a used (400 rounds) MCX pistol
Looks brand new
Also works with the MPX, or any other firearm that has a 1913 rail interface for mounting a brace
I might consider separating the knuckle from the SBX/tube if someone really wanted one or the other

Sig MCX "stripped" upper receiver (Legacy) - $300

Has 400 rounds total through the upper
Includes the newer ambidextrous "gas buster" style charging handle
Does NOT include a bolt carrier or bolt (hence being called "stripped") - this is the same way Sig sells the Virtus uppers except they want $100 for the charging handle (and $200 more for the stripped upper!)

Sig MCX Bolt (Legacy) - $80 SOLD

Fits Legacy barrels (non-tapered lug)
Does NOT fit Virtus barrels
400 rounds fired
Bolt only (with extractor) - no carrier or recoil assembl
Get yourself a spare, or use this to run a legacy barrel in a Virtus upper

Sig MCX 9" 300 Blackout barrel (Legacy) (CALX-MCX-9B-300B ) - $300 SOLD

This is the non-tapered bolt version (works with any upper, but requires an older Legacy bolt)
1:5 Twist
Does not have a taper-adapter for non-Sig muzzle devices (you can pick one up from Midwest Industries for under $10)
Has 50 rounds through it

Sig MCX 8" PDW Handguard (Legacy) (HGRD-MCX-PDW-BLK) - $80 SOLD

Keymod, fits Legacy uppers only, slim profile
Handguard works with the 9" barrel, allows a suppressor to mount past the handguard
Will combine with the 300 BLK barrel for $350 total

Sig MCX 11.5" 5.56 NATO barrel (Legacy) (CALX-MCX-11B-556) - $300 SOLD

This is the non-tapered bolt version (works with any upper, but requires an older Legacy bolt)
1:7 Twist
Does not have a taper-adapter for non-Sig muzzle devices (you can pick one up from Midwest Industries for under $10)
Has 350 rounds through it

Sig MCX 10" Carbine Handguard (Legacy) (HGRD-MCX-CARBINE-BLK) - $80 SOLD

Keymod, fits Legacy uppers only, slim profile
Handguard works with the 11.5" barrel, allows a suppressor to mount past the handguard
Will combine with the 5.56 barrel for $350 total

Prices are cash, FTF. Insured shipping is included in the prices above if you are an NWFA supporting member (otherwise at cost). I live north-east of La Center, and I work near downtown Vancouver. I'm pretty flexible to meet up most week-days with enough notice. Or PayPal (Gift, or you cover any fees).

PM me if you are interested. Don't be afraid to make me an offer...I'm a reasonable guy. But don't waste either of our time with lowball stuff - I'm willing to entertain fair requests.

If you want to package things up, let me know what you're looking for. I do have the Legacy bolt as well, but I'm holding onto it unless/until the barrels sell. The bolt carrier (minus bolt) isn't for sale though....
