GZP Custom Rifle ShopWe love the 300 Blackout round and all of its hard hitting, bacon-bulldozing goodness! With this love in our hearts and our years of experience with the round we set out to create the absolute perfect semi-auto platform for it. We wanted to create a rifle platform that not is not only capable of exploiting and enhancing the full range of loads and capabilities that the 300 Blackout encompasses but we also demanded that it to perform at an insane level of precision all while keeping the rifle as light weight as possible. We demanded nothing less than perfection in design, manufacture, function and operation of every single component we selected. We set the standard high and the bar higher. The result is this hand built custom 300 AAC Blackout pistol and it performs as reliably and with the high rate of precision that expected it would. Ready out of the box for reliable performance firing sub-sonic or super-sonic loads, suppressed or un-suppressed.

We designed this 300 AAC Blackout pistol from the ground up for high precision and jaw dropping performance in a compact, light-weight package. We start by hand fitting only the highest quality components and finish with a multi-round, multi-load function and accuracy test fire session. We do not accept and we will not ship mediocre. In line with the standard we set and with a complete understanding of the ballistic capabilities of the 300 AAC Blackout round we view 1 MOA as merely a benchmark to improve upon. We demand perfection and will not ship a custom shop 300 AAC Blackout rifle that fails to consistently put five test rounds in a 3/4" pattern at 100 yards. From start to finish our custom shop has only one goal in mind; to exceed the demands and expectations of hunters and sport shooters everywhere and we guarantee results.

Every single GZP Custom Shop rifle is hand-built with matched components, range tested for performance and custom laser engraved with its caliber, serial number of its matched lower receiver and the date it passed our demanding quality control inspection. Not a single GZP Custom Shop rifle will ever receive this engraving without first meeting or exceeding the performance expectations for which it was designed and passing our rigorous quality control inspection and not a single GZP Custom Shop rifle will ever ship without this engraving.

- Please enter your information or the receiving party's (the person that will be picking it up) information AS WELL AS the name, email and a good contact phone number for the FFL dealer you want us to ship your receiver to in the SPECIAL INSTRUCTIONS box while checking out. We will obtain the shipping address and other necessary information directly from them.
- If the dealer you are using to transfer a firearm has not sent us a currently updated FFL to put on file or is uncooperative with our request there will be an extended period of time needed to process your order.

There will be a 30% restocking fee on all lower receivers returned because of failed background checks. 

Federal law requires that you be 21 years or age or older to purchase a stripped receiver or frame. If a frame or receiver can only be made into a long gun (rifle or shotgun), it is still a frame or receiver not a handgun or long gun. However, they still are "firearms" by definition, and subject to the same GCA limitations as any other firearms. See Section 921(a)(3)(b). 18 U.S.C. Section 922(b)(1) makes it unlawful for a licensee to sell any firearm other than a shotgun or rifle to any person under the age of 21.
