Excellent build quality and great price
Review by
Do not buy the GSG version, it is very low quality compared to this official licensed HK MP5 by Walther. Excellent authenticity in every detail and this site had the best price by far of anyone I checked with... even lower than my own local gun shop's dealer cost! So obviously I went with GrabAGun. Outstanding. (Posted on 9/5/14)

Great Rifle
Review by
The HK MP5 A5 felt and looked like the auto MP5 A3 I shot at a range in Las Vegas. I cleaned the rifle before shooting, field stripping as instructed by the owners manual. At the range I shot a mixture of high velocity Winchester and Federal I had in he loading bench. Then rifle has an adjustible bolt speed, which I didn't bother to adjust. i fired 200 rounds with the one 25rnd magazine tha comes with rifle without a glitch, a nice surprise.

The front sight is adjustable for elevation by exchanging a replacement that comes with the rifle. Te rear peep sight is adjustable for windage and elevation and peep diameter is adjusted by rotation. The point of sight and point of impact were right on for me at 25yds. I was impressed with the accuracy with about 3 inch group unsupported standing. Trigger pull was good, smooth and crisp break.

This is a fun rifle and as of this date I have fired 600 rnds with only two malfunctions due to need for cleaning.. I have since purchased five more magazines, a picatenny rail and installed red dot sight. The accuracy is excellent considering this is a semiauto.
