What Reviewers Say
Quoted verbatim from YouTube reviews. Each link opens the video at the moment quoted.
This is probably the best single stage trigger I've ever felt in any rifle platform that is stock configurated.
This I love The Recoil impulse because it allows me to be predictable with the gun.
This rifle is not very balanced what I mean by that is it tends to be front heavy.
For people who have a bunch of AR-15s essentially people who don't own an AR-15 won't really be able to appreciate the uniqueness of the spear LT.
Relatively light but the moment you put anything on the front whether it be a light laser or hell even iron sights the spear LT start showing its BBW real quick.
