what's is the barrel material and bolt carrier group

Joseph, this pistol has a 4150 Chrome-Moly Barrel, Mil-Spec 8620 carrier and 9130 Azimuth 5.56 Sporter Model BCG. Details from DiamondBack : https://diamondbackfirearms.com/portfolio/db15pc300b8m/

Barrel is chrome-moly 4150 steel, bolt carrier is an Azimuth Technologies Sporter which uses 8620 steel for the carrier and 9310 steel for the bolt.

Is this weapon suppressor ready or would I have to make modifications?

Richard, should be good to go once you remove the flash hider and crush washer. Then you'd either need a suppressor threaded for 5/8"x24 direct thread or one of the many proprietary "quick detach" muzzle devices sold by many suppressor manufacturers to go with the can you purchase.

Richard, yes Sir it is "Suppressor Ready" as is. No modifications other than unscrewing the flash hider and screwing on your 5/8"x24 threaded Suppressor of choice.

Does this come with the SBPDW pistol brace shown? The spec only says "Pistol Brace".

it is a Maxim CBQ Brace checked by UPC and it is Diamondback DB15 .300 Blackout Pistol,******* Maxim CQB Brace, 8.5 Inch Barrel, 6″ Keymod Rail, Tactical Gray Finish, 30-RD, Diamondback DB15PC300TG8M

Is the barrel threaded and what is the thread pitch. Also what is the barrel twist? Thanks.

Michael, Barrel Twist Rate is 1:8 RH and Thread Pitch is 5/8-24.

Before I purchased the Diamondback pistol I was looking at doing a build because I couldn't find exactly what I was looking for. I had bought a Diamondback full size AR in 300 blackout and was well pleased with its operation. The Maxim Defense brace was the selling point coupled with my experience with the Diamondback brand sealed the deal. Since my purchase the weapon has performed very well and for the money I would recommend this AR pistol. Of course you can build or purchase a higher quality or performance weapon but for accuracy and operation it is well worth the price.
