I have a few mostly new MPX parts here since I sent mine to be SD converted.
ILWT 4.5” barrel with tri lug and threaded 1/2x38 with adjustable gas - has 50 rounds through it, shoots very well both supressed and unsupressed. $485
Midwest 8” handguard like new - $125
Lancer 14” carbon handguard like new - $225
OEM 16” handguard - $180
Not pictured - 16” factory barrel with TTI brake, shoots very well. Just the barrel no gas block assembly -$300
