Wikipedia Weapon Info:
The Heckler & Koch SL8 is a sporting rifle manufactured by Heckler & Koch. It is the civilian version of the Heckler & Koch G36.
To adapt the SL8 for the civilian market, the pistol grip and folding stock of the G36 have been replaced by a fixed stock with a thumbhole, and the receiver has been modified to prevent attachment of the G36 folding stock. In addition, to comply with the Gun Control Act of 1968 SL8 rifles exported to the United States have been modified so that they will not accept staggered, normal-capacity 20 and 30 round G36 magazines. U.S. SL8 rifles accept only a single-column, 10-round magazine. Other modifications have been made to the SL8 including a lightened trigger pull, adjustable cheekpiece and buttplate to customize the fit to the user, and a heavier, more accurate barrel. The SL8 does not come with the carry handle and built in optics of the G36, although these can be purchased aftermarket and fitted to the weapon.
As of July 28, 2010 the SL8-6 has been discontinued within the USA, with a MSRP last listed as $2499.00 USD.
