Why This Wins
After testing handstops from BCM to Strike Industries, this F1 Firearms model hits the sweet spot between the cheap airsoft-grade junk and overpriced “gucci” gear. The angled design gives better purchase than vertical stops when shooting from barricades – something I learned running carbine courses at our Spring TX range.

FAQ
What is M-LOK on an AR-15?
M-LOK is a mounting system developed by Magpul that allows direct attachment of accessories to handguards without needing rail sections. It’s lighter and slimmer than Picatinny.
Are foregrips legal on rifles?
Vertical foregrips on pistols may create an AOW under ATF rules. Handstops like this are generally unregulated, but check local laws.
Will M-LOK work on KeyMod?
No – they’re incompatible systems. We carry KeyMod-specific handstops if needed.
Where can I buy M-LOK handstops online?
F1Firearms (f1firearms.net) stocks this and other M-LOK accessories with same-day shipping from Flagstaff, AZ.
Does this require gunsmithing to install?
No – it installs in seconds with the included hardware. Just align and tighten.
Will this fit my AR pistol?
Yes, as long as you have M-LOK slots. No NFA concerns with handstops.
