Q: Will you build this left handed with no forward assist or dust cover?

Asked by: Ron - 11/19/2023

A: In order to build left handed we need left handed uppers and left handed bolt carrier and bolt assemblies and there has not been enough interest in left hand piston builds to put them in production. In machining we have to meet minimal numbers to run and the interest has just not been there.

Q: Hello, I’m looking to build a piston 300 blackout truck gun, and this seems to check all of the boxes. Is the piston gas system adjustable at all? I’m relatively new to piston systems so please excuse my ignorance. Thank you! Lyman

Asked by: Lyman Gillen - 3/23/2023

A: We do not regulate our 300BLK. You can read more at our blog as to why the 300BLK do not need to be regulated: https://www.blackriflearms.com/Our-300BLK-dont-need-to-be-regulatedSEE-WHY_b_14.html

Q: When piston upper is in place, what can I put in place of the buffer? What type of collaspable but stock is available? I am wanting to build a backpack weapon to carry in my job.

Asked by: Warrior Ammo - 1/16/2023

A: You could use the Strikes Industries PDW Viper stock and utilize our Enhanced Buffer, Spring & Buffer Tube Assemblies for Viper PDW Stocks & Braces - Gen 2. It's what we use and share a pic of our set up; however, the buffer tube in the page picture shows the Gen1 buffer tube we have since changed the design but hold the same tolerances. https://www.blackriflearms.com/Enhanced-Buffer-Spring-Buffer-Tube-Assemblies-for-Viper-PDW-Stocks-Braces--Gen-2_p_732.html

Q: Apologies to add to what I'm sure is an overwhelming number of messages and queries about stock and out of stock items, but I'm interested in purchasing two x 8" .300 Blackout Piston Complete Uppers w/12" Handguards (one of each or two of the same of either 12" handguard styles is fine). I tried to find the information on your website but was unable. Any ETA on restock?

Asked by: Hunter - 8/11/2021

A: We are expecting restock of all our uppers around end of summer. Barrels are in production now and waiting on nitride and barrel extensions are at NiB waiting on plating so almost there.

Q: I am interested in your gas piston 8" .300 Upper. Who's BCG do you use? Is it full auto rated? Who's gas block do you use ? Is it adjustable? I plan to use a Fostech Echo II binary trigger Any issues? I plan to suppress it. Isues? Do you have a recommendation for a suppressor? Thanks Dave

Asked by: Dave - 12/20/2020

A: Our piston systems are patented by our owner, so our bolt carriers, gas blocks etc are manufactured by us. In a 300BLK you do not need to regulate the system. All of our piston systems can run full auto (we R&D, etc only using full auto and we suppress also). All our systems can be used full auto with no issues. Charles uses OSS and Dead Air Silencers. You may learn more about our 300BLK by going to our piston video page and scrolling down to 300BLK Piston Video: https://blackriflearms.com/PISTON-VIDEOS_ep_40.html
