Suggesting merge into Action (firearms)

 * Strong oppose, as for all these (and they should have been noted at Action (firearms) too). Andy Dingley (talk) 12:18, 3 March 2017 (UTC)
 * Oppose. Blowback can have a very detailed discussion that would be inappropriate at Action. Glrx (talk) 23:30, 9 March 2017 (UTC)

Screw Delay is distinct from Radial Delay
The revert of the radially-delayed section was uncalled for. Reversion description stated that it was 'screw delay'. In fact, it is not and it is quite distinct from that. The radial-delay is most akin to a lever delay. The rotation of the bolt acts on a cam on the bolt carrier. For 1x of rearward movement of the bolt itself there is a 4x movement of the bolt carrier. Screw-delay is a simple friction delay with no mechanical disadvantage as in the radial delay. Listen, if you don't understand this stuff, don't revert other people's posts who DO understand it. --Winged Brick (talk) 08:19, 11 June 2017 (UTC)


 * Please supply a reliable secondary source for the action. An encyclopedia is not the place for every new little thing. WP needs an RS to tell it that radial delay is significant. Per WP:BRD, consensus on this page is needed to reinsert the material. Glrx (talk) 14:44, 11 June 2017 (UTC)
 * Uh, the NRA is not a reliable secondary source? New, yes.  Little?  The gun is in production.  The operating system is novel.  In fact, it is one of the first NEW operating systems in the last 100 years.  Give it a rest and find your own resources that contradict what I've written.  Don't be a jerk. You don't understand the material.  I understand it might be beyond your comprehension.  That doesn't mean that it is inaccurate. --Winged Brick (talk) 03:02, 12 June 2017 (UTC)

Colour illustration for roller-delayed blowback incorrect?
Given my limited knowledge about various blowback mechanisms, it still seems as if the colour illustration for roller-delayed blowback is incorrect. Currently, the locking rollers (purple) will push onto a parallel section of the locking piece (light sand), as the cartridge tries to move rearwards. Consequently, the rollers will not be able to move inwards, the bolt head (pink) will stay where it is, and the weapon will not reload. Instead -- as indicated by the subsequent b/w drawing -- the sloped shoulders at the left-hand end of the locking piece must reach far enough to the right, so that the locking rollers will rest on them. Now, when the firearm is fired, the bolt head is pushed to the right by the cartridge. This causes the locking rollers to be pushed inwards, which squeezes the locking piece to the right. As a consequence, the bolt will be accelerated more than the bolt head, and (blah, blah, blah, further consequences). — Preceding unsigned comment added by 87.56.129.70 (talk) 15:21, 24 September 2018 (UTC)
