What tools and additional parts are required?

For parts – most setups will require a low profile gas block to sit under the handguard – most barrels will work with the handguard.

For tools – we recommend:

  • A vise and non-marring vise block for holding the upper
  • Roll pin punch and non-marring hammer for driving in the forward assist pin
  • A torque wrench and breaker bar to assure you stay in the AR-15 barrel nut torque range while timing the barrel nut (30-60 ft lbs)
  • Blue Loctite for the mounting screws

Awesome Combo!

Ordered the FDE combo for my 300BLK rig, been wanting to for a while, and saw this combo come up, so I jumped on it. First off, the color was spot on, matched my magpul grip and buttstock perfectly! Everything went together easily and seemlessly, perfect fit, snug,nothing loose. Love the way the handguard and upper have the piece that "interlocks"to make lining up the rails a breeze! Oiled everything up, and Cycled the charging handle about 30-40 times...give it that quick "break in" and was smooth. Took it out to the range and ran my last 200rds thru with zero issues.
Very happy with this purchase, well worth it! Thanks guys!

Thanks for the great review! We're glad you're happy with your purchase!

Forged handguard/lower

Over all quality is good. My only complaint is the the aluminum barrel nut. It feels weak and cheap. Other than that the product is quality
