Lee Sporting Aluminum MP5 / SP5 K Push-Pin Lower Housing

Billet Aluminum trigger group for MP5 variants. Excellent ergonomic upgrade to semi-auto MP5's. Firing hand is shifted forward .6" and up closer to the bore axis .4". Ability to use match AR triggers reduces split times and makes precise shots more accurate. Ejector lever is CNC machined from 4140 alloy steel and nitride coated. File-To-Fit may be required as each MP5 is individually welded. HK brand guns are more likely to require File-To-Fit. Weight (empty): 6.2 oz.
