Yhm handguard - Yankee Hill Machine Rifle Length Diamond Forearm AR-15 YHM-9635-DX

Fits flawlessly. I would definitely recommend it. The handguard does need the the end cover. I believe it is another 20 bucks but it is well worth it. I plan on gettin another one for my other build I am working on. You can’t go wrong with Yankee hill. They have been doing this from the get go. My whole at build is YHM.
