Today I am out at the range to do some side-by-side shooting with the CETME-L and the CETME-LC. These are both MarColMar examples, in the original Spanish military configuration (ie, iron sights only). The LC model has a bit snappier recoil and more muzzle climb, which I suspect is due to the different recoil spring assembly it uses in order to accommodate a collapsing stock. The difference is small enough that it is not noticeable unless shooting both model side by side.
Still, the LC is my choice of the two. While is really doesn’t weigh significantly less than the full-size L model, I like the compactness and the better handling it gets as a result. Unfortunately, this comes at the cost of NFA registration.
