The LBE Unlimited AR-15 A2 Pencil Sight Tool (part no. ARPSTL) is the four-prong tool built to turn the detent on a standard A2 front sight post, letting you adjust elevation without improvising with a cartridge rim or a bent paperclip. LBE Unlimited machines it from steel so it holds up to repeated use at the range or in an armorer’s kit. It’s a small, purpose-built tool worth keeping in a range bag for anyone still running iron sights on an A2-profile upper.
