Parker Mountain Machine (PMM), well known for their pistol compensators, have recently announced their take on the triangle stock, affectionately named the Trongle Stonk. The Trongle Stonk is based on skeletonized triangle stocks sometimes seen on AK-style rifles, however, this is moreso designed to work with SIG Sauer’s MCX and MPX, but does require a separate hinge. The Trongle Stonk also includes two M-LOK slots on top of the stonk, I mean stock, which could accept a cheek rest.
Parker Mountain Machine @ TFB:
The following is Parker Mountain Machine’s description from their website.
The Trongle Stonk is our take on the triangle stock popular on many COMBLOC firearms. We have modernized the design, making it compatible with Sig Sauer pattern hinge assemblies, the addition of a QD Mount, Sig Sauer rubber buttpad, as well as incorporating two M-LOK slots at the top of the stock.
These are milled from blocks of 6061-T6 aluminum, creating a lightweight and extremely durable end product.
The Parker Mountain Machine Trongle Stonk is listed at $160.00. Since it requires a separate hinge, feel free to list aftermarket hinges or folding knuckles that you would use in conjunction with PMM’s new triangle stock. TFB writer Nick C. said that he’s used the older style folding knuckle from SIG in the past, while Matt E. recommended JMAC Customs as another option. You can view the new triangle stock HERE, or visit PMM’s main website, ParkerMountainMachine.com to see the other products they offer. You can follow their Facebook, Instagram and Reddit pages, or subscribe to their YouTube channel.
