Equivalent spring power of a “fresh” AR15/M4 carbine action spring, this spring is for users who do not want to dabble with improving performance with extra power springs, but do not want to frequently replace their action springs as well

The option with the most spring tension, this spring is suited for rifles and carbines with excessive bolt speeds.

    Hello, the reason I did a 4 instead of a five is because I specifically ordered the 3 position fire/safety option lower with safe semi and auto but I received just the everyday boring regular semi and safe 2 position. The reciever I received is fine and great no issues some things were very loose and seemed quickly put together but those were no big deal at all since I’m stripping the lower and replace all parts but ya I wouldn’t have ordered it had I known I was getting the regular 2 position version. That said, it’s a great lower everything seems perfect I like the company logo I like that it’s on the right side instead of the left. It’s comfortable and quality and will work perfectly well for the latest build im doing.i plan on making many more purchases here in future days
