Strike Industries used their Facebook page to announce a potential New Year’s treat. Apparently they are developing a drop-in aluminum H&K MP5 receiver that will work with standard trigger housings. The new gun will also use standard H&K barrels, charging handles and magazines. No word on if the signature MP5 delayed roller lock action will find its way into the Strike variant, but we still have a few weeks before the 2017 SHOT Show.

Dubbed the SI 2017, the pistol or rifle has a full length top rail and modular attachment points on the forearm. It also appears to be ambidextrous, with the option to switch the charging handle to the right side. The rifle prototype sports a Sig Sauer MPX/MCX folding stock, with a rail attachment point for other stock options.

Strike CEO Garrett Keller graciously responded to an email request for additional information. He writes:

First and foremost we are keeping the system true to the standard MP5 being one of the most widely used platforms for LEO/MIL worldwide. We don’t want them to have to retrain to new operating procedures so still no bolt lock back. Compatible with the already widely available MP5 Lower Receiver, Bolt and trigger pack, what we are aiming to provide is an updated modular upper with, barrel, handguard, and stock configurations for pistol, sbr and rifle options “user choice”. It will feature continuous top rail, MLOK rail system, integrated flip up front and rear sights on all length options except the shortest length due to structural limits and feature an ambi charging handle. More updates coming soon!

Keller also shared some design drawings:

After seeing the mock ups and getting a few details from Keller, I have to say I’m pretty excited. The rest of the details are under wraps at this time. Interested? Keep an eye on the Strike Industries Facebook page (and TFB) for more information.
