This is a cool gun! Was purchased after light training use from the Cãnon City, CO police department. Full metal upper and lower. Here’s a review from Airsoft GI: https://www.airsoftgi.com/information/font-color-blue-Armalite-M15A4-Review-1 So whether you’re doing a Heat reenactment kit or just want a solid HPA donor body, or a reliable AEG, this one’s for you. I’ve got 4 of these so hit me up for bulk pricing when you buy more than one. Check my profile and buy with confidence! Shooting video available upon request. NO TRADES
