Description
Bolt BA037 Scale Panel (Black)
This is the black version of Bolt Airsoft’s BA037 Scale Panel, a handguard rail panel with a scale-textured surface. Black blends in with most M4 handguards for a clean, uniform look, while the texture gives a positive hold for your support hand.
Rail panels are a small but practical addition to a rifle. They cover unused rail sections, protect your hands from sharp edges and make the rifle more comfortable to hold during long games.
Practical benefits
The scale texture helps your hand stay put in wet or muddy conditions, and covering the rail stops it snagging on gloves, slings and kit. Panels also protect the rail itself from scuffs.
Because they can be placed only where you need them, you can keep space free for lights, foregrips and other accessories.
Setting up the handguard
Work out where your accessories will sit first, then fill the remaining space with panels. Black panels keep a low-key, uniform appearance, which many players prefer for a classic M4 look.
If you want to add contrast or match a tan loadout, the BA037 is also offered in tan.
Before you order
Rail systems vary, so check your handguard’s rail type and look at the product photos to confirm this panel suits it. Fit and remove the panel with the replica unloaded and the battery out.
