I used this nailer to install 700 sq ft of oak T&G flooring. The nailer worked great with no issues. Per the manufacturer:
The NuMax SFL618 Pneumatic 3-in-1 15.5-Gauge and 16-Gauge 2" Flooring Nailer / Stapler with Flooring Mallet and Interchangeable Base Plates is ideal for the installation of tongue and groove hardwood flooring. A 3-in-1 multi-purpose magazine allows both nailing and stapling with just one tool, saving time and money. This durable and lightweight air powered flooring nailer / stapler features a semi-quick jam release and an ergonomic handle. Two interchangeable no mar base plates protect even finished flooring surfaces from damage, ensuring professional results for DIYers tackling home improvement and repair projects as well as construction contractors at the jobsite. The Pneumatic 3-in-1 15.5-Gauge and 16-Gauge 2" Flooring Nailer / Stapler includes a long reach fiberglass mallet with padded grip.
