Morphology

retard + blowback

The constituents 'retard' (to slow) and 'blowback' (gases pushed back to cycle a firearm) combine to give the straightforward sense of 'slowed blowback', so a learner who knows both words can infer the general idea. However, the precise mechanical nuance (the bolt must overcome initial resistance yet is not fully locked) is specialized technical information not predictable from the words alone, so the expression is only partially transparent to a B1 learner.

Etymology

The noun retarded blowback comes from a simple image: retarded means 'slowed' and blowback is the 'back push' of gas on the moving part of a gun. Imagine a heavy door a strong wind tries to push but a chain holds for a moment, and that short delay is why the term means a gun system where the moving part must overcome a first resistance before it moves.
