for you AR-15 fans out there

Years ago, Crosman had an AR-15 upper. I guess it went out of production, and wasn't even on the web site for a long time. It's back!

It's Expensive considering it's only an upper and you still need to have a lower (which is regulated because that's where the serial number is).

Has anyone ever used one of these and are they any good? The Lothar Walthar barrel says it should be able to hit something, but is it worth the $650?
 
Never saw this before, kinda cool but not at the cost of $650 for a .177 cal. More power might be interesting though. As far as legality is concerned, the upper appears as having a barrel that is over 16", which means you can attach it to any lower with no issues. True the lower is the serialized part however unless the lower is registered with the NFA, it is illegal to attach an "upper" onto it that has a barrel under 16" in length.
 
You can always get one of the 80% lowers and finish it. Then you have a lower with no SN#. Not vary expensive price wise and easy to finish with just a drill press. The upper on the other hand at 650.00 is about twice what you can get a 5.56 upper for. Would be a fun project. Would also be nice to have all the information and pictures of the upper. They are just a little short on information. Sylvan
 
Unfortunately the code states:The term “firearm” means (A) any weapon (including a starter gun) which will or is designed to or may readily be converted to expel a projectile by the action of an explosive; (B) the frame or receiver of any such weapon; (C) any firearm muffler or firearm silencer; or (D) any destructive device. Such term does not include an antique firearm. So yes, because of the receiver it is by definition a firearm. I had one and shot in the basement but was not able to use it in a FT event.

The upper air rifle conversion was intended for an affordable indoor off season practice for NRA high power service rifle competitors. You can practice 10m indoor shooting standing, kneeling or sitting and prone with your AR15 lower and aperture rear sight and front post. Use slings for prone and kneeling or sitting. Single shot only.
