Makita Genuine 345839-7 Stopper Base for Makita BFR550 Screwgun

The Makita 345839-7 Stopper Base is a genuine OEM replacement part for the nose assembly on Makita magazine-fed screwguns, restoring accurate screw strip guidance and consistent driving depth.

Moulded from a durable, impact-resistant polymer, this component is built to withstand the demands of regular site use. When the original stopper base becomes cracked, worn, or distorted through heavy use, misfeeds and alignment issues quickly follow — fitting this genuine replacement brings the nose assembly back to proper working order and helps protect surrounding components from accelerated wear.

Designed for Makita screwguns in the BFR and DFR family — including the BFR550 and 6843 — this part offers an assured fit straight from the manufacturer. Precision-engineered interfaces maintain stable alignment within the nose assembly, supporting smooth screw strip feeding, reduced jamming, and consistent driver bit engagement across extended use.

Installation is straightforward using basic hand tools, making this a practical maintenance choice for professional contractors and tradespeople looking to keep their screwguns running reliably on site.
