About Four Uncles
Four Uncles is an Amazon-native hand pump brand that was previously misidentified in this database as 'Four Cousins.' Its FU-PP02 is a 3-stage hand pump built around stainless steel construction and an 8mm copper quick connector, and it has accumulated a large, strongly positive review base for a budget accessory. An independent firearms review blog ranked it the top pick among the PCP hand pumps it tested by hand.
