Our Assessment: The Heckler & Koch SL630 is a rarely encountered sporting rifle built on the same roller-delayed blowback system that made HK’s military rifles world-famous. Produced in limited numbers during the early 1970s, it was HK’s attempt to enter the commercial hunting and sporting market with a semi-automatic chambered in .223 Remington. The SL series rifles carried over HK’s engineering pedigree while being refined for civilian use, with features such as checkered walnut stocks and sporting-style sights. Built in 1972, this rifle is C&R eligible and represents a fascinating chapter in HK’s history, showing how the company adapted its proven military design for hunters and target shooters in Western Europe and the United States. This particular example remains in very fine condition, retaining about 97 percent of its blued finish with only minor wear from handling and operation. The barrel extension shows the typical plum coloration often seen on HK finishes, while the rest of the rifle remains clean and well-kept. The chrome-lined bore is in outstanding shape, bright with sharp polygonal rifling and rating a perfect 10 out of 10, making this rifle not only collectible but also a superb shooter. The original checkered walnut stock shows shallow splitting on the left side, which brings the overall furniture condition down, though the stock remains serviceable and complete with sling loops and its original plastic buttplate. The included 10-round magazine is in excellent condition, adding to the rifle’s desirability.
For collectors of HK firearms and European sporting arms, the SL630 is an uncommon and highly desirable piece. With its roller-delayed action, it carries the DNA of the G3 battle rifle and the precision of HK’s engineering, while standing apart as a purpose-built sporting arm. Its rarity in the United States, combined with its excellent bore, original finish, and intact magazine, makes it a strong candidate for any advanced collection. Whether displayed as part of HK’s civilian sporting legacy or enjoyed on the range with proper care, this rifle offers both historical significance and practical performance in equal measure. -R.E.
