One detail tipped me off: the sharp-cornered internal machining inside the receiver. This type of machining can only be achieved using specialized manufacturing methods, yet I doubt those would be applied to a low-cost shotgun from this brand. On the rear face of the receiver, rectangular weld marks are visible. I would say it is silver brazing or a similar process.<!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAIIRAA\" data-complete=\"true\" data-processed=\"true\">Rear face of a Squire Bingham pump-action shotgun receiver.<!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAIIhAA\" data-complete=\"true\" data-processed=\"true\">Below you will find photos of the rear of the receiver with and without the attached piece.

The receiver is made from a single piece. It would be interesting to create a synthesis (physical or digital) between the Squire Bingham and the 870\u2014namely, a pump-action shotgun featuring a one-piece steel receiver and a fixed barrel. There would likely be pros and cons. To be seen\u2026 that is another topic.<!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAIJBAA\" data-complete=\"true\" data-processed=\"true\">Rear face of the Squire Bingham pump-action shotgun receiver.<!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAIJRAA\" data-complete=\"true\" data-processed=\"true\">Rear plug of the Squire Bingham pump-action shotgun receiver.<!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAIJhAA\" data-complete=\"true\" data-processed=\"true\">Rear face of the Squire Bingham pump-action shotgun receiver.<!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAIJxAA\" data-complete=\"true\" data-processed=\"true\">Rear face of the Squire Bingham pump-action shotgun receiver.<!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAIKBAA\" data-complete=\"true\" data-processed=\"true\">The bolt locking recess is machined directly into the receiver. This could be an issue if the barrel were removable by the user. One would then have to ensure the part was properly fitted so that headspace remained within tolerances. Here, the problem is solved by having the barrel permanently secured to the receiver.<!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAIKRAA\" data-complete=\"true\" data-processed=\"true\"><strong class=\"rQesXe MPyX\" data-sfc-cp=\"\" data-sfc-root=\"c\" data-complete=\"true\" data-processed=\"true\">The bolt<!--TgQPHd|||[]--><\/strong><!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAIKhAA\" data-complete=\"true\" data-processed=\"true\">The bolt and the locking block are a single piece. The locking block is the small angled projection located at the rear, on top of the bolt. At the end of its forward travel, the rear of the bolt tilts upward and engages its recess (in the receiver).<!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAIKxAA\" data-complete=\"true\" data-processed=\"true\">The bolt of the Squire Bingham pump-action shotgun.<!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAILBAA\" data-complete=\"true\" data-processed=\"true\">Right side of the bolt.<!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAILRAA\" data-complete=\"true\" data-processed=\"true\"><strong class=\"rQesXe MPyX\" data-sfc-cp=\"\" data-sfc-root=\"c\" data-complete=\"true\" data-processed=\"true\">The barrel<!--TgQPHd|||[]--><\/strong><!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAILhAA\" data-complete=\"true\" data-processed=\"true\">The steel barrel is cylindrical.

To remove the forend, the magazine tube must be unscrewed from the receiver. This is due to the presence of a retaining collar and a spring on the exterior body of the magazine tube. These prevent the forend from being removed from the front. It must slide off the rear of the magazine tube, so if you want to clean your firearm properly from time to time, you have to remove the magazine tube.<!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAIPBAA\" data-complete=\"true\" data-processed=\"true\">View of the magazine tube parts that prevent front removal of the forend on the Squire Bingham pump-action shotgun.<!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAIPRAA\" data-complete=\"true\" data-processed=\"true\">The magazine tube, its collar, and its spring.<!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAIPhAA\" data-complete=\"true\" data-processed=\"true\">Four holes at the front of the magazine tube (two of which are used for the magazine cap screws) can be used for this purpose.

This is a deliberate choice by the manufacturer. Why should we go beyond the manufacturer&rsquo;s intent? If the firearm is new, very well maintained, or still under warranty, I believe it is inadvisable to separate the two parts. On the other hand, if the firearm requires a deep overhaul\u2014such as re-bluing, heavy rust removal, bore polishing, sandblasting, or reaming the chamber to magnum\u2014then removing it becomes

Otherwise, headspace would have to be checked to stay within the tolerances defined by CIP standards, or the locking recess would have to be integrated into the barrel, as is the case on many pump-action or semi-automatic shotguns.<!--TgQPHd|||[]--><\/p>\n<p class=\"n6owBd awi2gc\" data-sfc-root=\"c\" data-hveid=\"CAAIVhAA\" data-complete=\"true\" data-processed=\"true\">The trigger group is conventional.
