The satisfying weight of a .50 BMG or .338 Lapua round in your hand signals serious firepower, but only if it’s within immediate reach. This quick-install spare round holder puts two of your most important backups right at your fingertips, so you’re always prepared when the stakes are high.
Let’s walk through the simple setup.
Step 1: Find the Right Mounting Spot
Identify a free M-LOK slot along your firearm’s handguard. Placement depends on personal preference:
-
Left/Right side rail – for easy thumb or weak‑hand access
-
Bottom rail – for balance and accessibility in prone position
Step 2: Attach the Holder
Start by aligning the base plate of the holder with your chosen M-LOK slot. Next, insert the supplied M-LOK screws or fasteners through the holder and into the slot. Finally, use a hex or Allen key to tighten the screws until the holder feels securely snug against your handguard, ensuring a firm, stable fit without over-tightening.
⚠️ Tip: Tighten firmly, but do not overtighten to avoid damaging your handguard or screws.
Step 3: Secure Your Rounds
To load the holder, slide each spare round securely into the elastic retention strap, making sure the rounds sit flush against the carbon fiber polyamide frame. Once positioned, check that the rounds are snug enough to stay in place but can still be pulled free quickly when needed. This balance of secure fit and ease of access is vital for reliable performance in the field.
Step 4: Field Use
During shooting sessions, you can easily reach for the spare rounds directly from the holder, getting quick reloads without fumbling. Thanks to the elastic strap, the bullets stay securely in place even during vigorous movement or recoil. This quick-access design not only reduces your reload time but also gives you the confidence of knowing your spares are always within reach when you need them most.
Step 5: Maintenance & Customization
If the elastic strap shows wear, replace it with the included spare strap. Wipe down the holder after exposure to dirt, dust, or moisture to maintain durability. Because of its carbon fiber polyamide build, the holder is rugged yet lightweight—no extra bulk on your setup.

Final Thoughts

Mounted in minutes, it keeps your ammunition close and your focus sharp. When every moment counts, this small but essential upgrade ensures you have what you need exactly when you need it.
