Perfect kit. This is the second one I have purchased from PSA. Never had a problem with either one and never had a malfunction either. PSA is the best, high quality for good price.

Great bang for the buck!!!!
Everything I have bought from PSA has always been great quality. Including the freedom rifle kit. From unboxing to putting the rifle together... The rifle shoots and feels very solid for an “entry level” rifle. I put about 500rds through it with no issues. I highly recommended PSA products.
