HOUSONAR Folding Stock Adapter, Aluminum Side Gussets Buttstock Adapter for AR15 M4 A2 AK

The "official" purpose of this device is to allow owners of certain rifles to add a folding stock to their firearm. For example when playing airsoft, or leaping heroically from helicopters. But, as a cosplay and prop maker that's not quite my plan for this handy little object.Yes, I will still be used to create folding stocks for rifles etc. But this won't be used for real world rifles.Instead I'll be using this for sci-fi blasters and and similar kinds of things.A job this will do nicely because it's made from solid aluminium. Which is incredibly durable, lightweight and above all prop-maker proof.I also know it will be easy to attach to a variety of materials. From plastics to metals to wood. Then, because it's so solid, I know this will last me a long time. So I can easily reuse it for other projects.

Bad Thread so no use

Edit: My review has been rejected many times now for no given or apparent reason, so I'm now seeing if removing most of my 'fitted' photographs allows it through.The removed photos showed this fitted to a modified (Airsoft) APS CAM 870. It has a non-standard AR stock/grip adapter, which this HOUSON folding attachment fits perfectly.For reference, the tube thread measures 28.75mm (1.13") internally and 29.75mm (1.17") externally.For those unaware, these AR-style stocks typically screw into the rear of the receiver and secure with a castle nut. This HOUSON folding adapter sits between the receiver and stock, adding a folding mechanism to a normally static stock. It locks into the fully open and fully closed positions with a detent and spring.Note that a castle nut spanner is not supplied, and you'll need one to securely fit this.While in the extended/full position, it sits very securely with no wobble. There is a chunky detent into which it sits when 'open'. Unfortunately in the folded position there is considerable vertical wobble. The tolerances on the hinge pin/barrel are not great.After only two folds/locks I've noticed the black finish is coming away. More than that, the (apparently quite soft) aluminium is wearing away where the two halves contact; there's a cam-like mechanism that will wear quickly unless you are very careful to fully depress the spring before folding/unfolding the stock.I have a G&G LR300 which has a very similar hinged stock system; but that's made of steel and is basically indestructible. This is not. If you do skirmish this part, you'll need to baby the thing when folding/unfolding the stock to avoid destroying it in short order.Overall the finish is... acceptable for the money. Various rough edges are to be expected at this price.
