The gun addon (TACZ) from MCPEDL I introduced before

Whoa! So you actually installed the add-on I told you about before. Its intricate gun design is as beautiful as any Silvarka craft. Master the minigun too and make your cave explorations more advantageous, whoa!

I don't have a minigun, but for addons, I recommend uplokguns 1.7 (1.8 has an item that opens the settings menu fixed to the hotbar). While tacz is superior in terms of realism and item count, I think this one fits the Minecraft atmosphere better. Also, for those looking for something simple, there's guns+. It lacks custom elements and has fewer guns, though. It's not that there aren't other gun addons for the Bedrock Edition that work properly, but I don't use the ones with flimsy item icons or the sci-fi types because they're not to my taste. ...In short, personally, I think the three gun addons, uplok (matches Minecraft), takz (focuses on realism), and guns+ (the simple one), are safe bets.
