Words having meaning and you're missing a crucial one..."delayed".Does the action lock at all? Even for a milli second or is the action constantly moving? I have been calling it a "ROOLER LOCK", but have been told I'm wrong; there is no actual "locking". Am I wrong?
No. It's Halbstarrverriegelt. Half-locked. Semi-rigid.Does the action lock at all?

Correct. But Mauser tried to come up with a 'more cost effective' design to compete with and hopefully replace the already adopted Haenel MP43/MP44/StG44. To convince the german authorities to do so, the new design had to prove substantial improvements performance- or cost-wise. So simplification of design and production process was paramount. The first design, the Geraet 06, featured a roller locked design, similar to the MG 42, but with the stationary barrel and the locking piece actuated by a gas system. Though easier and cheaper to produce, production was still not sufficiently cheaper than that of the StG 44 to justify the adoption of a new rifle, especially in the last months of WW II.The STG-44 is a tilt locking bolt. Similar to a FAL.
It doesn't lock. The rollers only delay the opening of the blow back action.Um, now I'm confused; does it lock or not? I was SURE it did even if only , temporarily because the charging handle has to "UNLOCK" the rollers before charging takes place. And the way Marine0303 described it sorta made sense. Even reading the FULL CIRCLE book gets kinda technical, too.

No. Rifle caliber HK roller guns have a Rücksprallsperre bolt rebound lock which latches the bolt carrier to the bolt head on closing (and therefore rollers into the recesses because the locking piece is forwards) to avoid bolt bounce problems during full-auto firing, although it's also semi-rigid not locking - pull hard enough and the bolt head extends forwards from the carrier. Unfolding the charging handle provides mechanical leverage against the the bolt carrier so it takes less force to overcome that resistance.even if only , temporarily because the charging handle has to "UNLOCK" the rollers before charging takes place.
This is all in _Full Circle - A Treatise on Roller Locking_ by R Blake Stevens who also wrote _The Black Rifle: M16 Retrospective_. If you were an annoying kid like me that always wanted to know "Why?" that has answers, along with names and dates I always forgot after history tests. If you studied German like I did because engineering schools required a foreign language and those guys are really technical you'll wish you remembered more.Even reading the FULL CIRCLE book gets kinda technical, too.
