❓ Frequently Asked Questions (FAQ)

Q: What’s the difference between free-float and drop-in AR-15 handguards?
A: Drop-in handguards are easier to install and clamp into the standard delta ring and cap. Free-float handguards mount directly to the upper receiver, reducing barrel contact and improving accuracy.

Q: What length AR-15 handguard do I need?
A: It depends on your gas system length (carbine, mid-length, rifle) and barrel size. Common sizes range from 7” to 15”.

Q: Is M-LOK or KeyMod better for handguards?
A: M-LOK is now the industry standard—more durable and widely supported than KeyMod.

Q: Can I install a handguard myself?
A: Yes. Drop-in models require minimal tools. Free-float rails need a barrel nut wrench and vise block, but are doable with basic tools.

Q: Will these handguards work with all AR-15 uppers?
A: Most are MIL-SPEC compatible. Always check the product details for fitment with billet uppers or specialty barrels.
