Triggrcon 18 – Fortis Manufacturing

The Lightweight Endplate (LE) was designed to eliminate the requirement to stake Receiver Extension Castle Nuts.

It comes in two styles, the K1 is a tapered thread and the K2 uses an Omega Clip which slides into a slot and captures everything together. Either version requires just 15 inch pounds of pressure to install.

    Is there any benefits of this one over the PWS one? This one looks more bulky.

    Very interesting but Im not as knowledgeable on ARs as I wish I was. Can someone explain how & why this is such an advancement in AR tech

      Like most modern tools, everything at this point is simply incremental improvement. Weight saving, tool-less install, increased duty life, etc.

    Castle nuts are staked to prevent them from walking out. If it walks out your buffer tube can become lose and possibly throw your retainer and spring into the tube or your bcg. Also that retainer ring is responsible for keeping your end plate on. End plate retains the spring for the rear takedown pin detent. This keeps your rear takedown pin from walking out. If you have ever seen an ar with the rear takedown removed it kind of pez dispensers open for cleaning, pivoting on the front take down pin. Now imagine this occurring at some point during the cyclic process of firing the weapon. Kind of why manufactures stake their castle. Non staked is good enough for my moms basement but not for a cage number. As per how and why this product seems to use a different function to lock the castle in place and it’s gold anodized so it’s game changing. By my experience in call of duty:MW2, ghost recon and THE game (the game meaning craps) chances of it popping up in a team room are probably slim. Look for this along with other skelotinized accessories at your public range’s next static 1r1 in full kit larp fest. That was salty at the end, disregard my hate. Kind of a cool product. People will buy it. Hopefully i answered your question. I was bored. Namaste.

    So torn between my love and nostalgia for the pure AR15/M16 family of weapons and an appreciation for the new products that keep prolonging its life. I think that staking is a simple, easy to do process that makes sense in the context of the original design, but I also understand that there can be other ways to solve the problem. Not sure which is “better” but I know which is the least expensive and proven to work. Under normal use for the purpose the weapons were designed for, there is little need to ever remove the receiver extension. However, today the lego-like hobby of building guns sees frequent upgrades and parts swaps, so I see the appeal of this system. I am beginning to think we are nearing the end of any real improvements, with incremental (at best) changes more the story. The never-ending bro-cessorizing of the AR is an industry within an industry.
