Do the barrel threads on the FCR m-lok upper stick out far enough to mount a YHM QD flash suppressor and suppressor? Looks pretty close? Any input? — 1 Answer

The Radical Firearms 10.5 in. 5.56 M4 Upper Assembly FCR handguard model has a 10.5" barrel and a 10" handguard. It may prevent the YHM QD Flash hider and suppressor from being mounted without contacting the handguard. Please email us at techsales@opticsplanet.com so we can get more information regarding your specific suppressor to see if it will be compatible.
