The SMLE 303 bolt action is the best ever battle rifle of all time, the SLR is perhaps the best semi-auto battle rifle.

“We had a major issue with stopping power with the SA80” said Lt Gen Ian Wallace, Deputy Director of Defense Armaments, “The weapons system was simply not powerful enough to put down the enemy. With the new SLR-A2, you can guarantee that it will not fail with that task.”

Well who would have thought. There were plenty of warnings given back then when the 5.56 was adopted that it would fail, it did and it's been a failure ever since.
