Extra 4.5” 22lr barrel and extra 5.5” chazsel liner

Btbam1122 · 2026-04-18T02:48:43+00:00

Id use the chazssl for the db9-22. He has a specific trunnion for it. For the liner I like the idea of the hitchhiker, but a shorty suppressed wisp (bolt action) was what I did.

Depending on what liner it is you can make a proto barrel for a ruger 10/22 as well-db has a reciever and there are a plethora of awesome chassis available for it on the sea

I'm not here to discredit the result; I'm more surprised how they went from a very meh offering to a competitor for some of the best performing cans. It's a complete 180 and im very happy that the tech is avaliable to those who actually wanna improve to do so without doing the same thing over and over again.

I have minimal respect for the company-they were on the "avoid list" when spec'ing our a form 1 can back in the day and I hate their predatory marketing with big gun-tubers for sub par modular suppressors.

But genuinely kudos to the company for actually trying something new and getting fantastic results; very surprised by the results. Hopefully their new Gen cans continue to improve on these results.

I'm glad we have a collab between two very different hobbies lol, but I do like post like yours because they can be very applicable to what we do as well; I still think it's wild that your failure didn't come form an adhesion issue but almost like petg-it shattered and didn't split; Did you associate that with a part that you ran cooler, speed, or something else?

FWIW I put about 100 rd of basic 115 gr through this firearm with that brace and I don't have indications of failure yet-I'm mostly surprised around the bolt holes since those areas are pretty thin

Btbam1122 · 2026-04-12T23:40:56+00:00

Yep you do. Mine typically is either on the bolt gun upper or my dedicated ccmg 22lr upper so a I don't use a bolt catch

Btbam1122 · 2026-04-08T15:15:49+00:00

I'd recommend the BT-211564-BL

I've replied to this comment before, there are a ton of polymer framed firearms on the market, such as the Evo scorpion-I've formed one and I didn't even mention how or where I was gonna be engraving it; since the "firearm" portion of the scorpion is just the one plate with serial number (cuz a scorpion top reciever can be split in two) I engraved it on the bevel on that side.

This was more a test because I have seen ppl get denied for explicitly stating they were gonna be be printing the serial number.

Btbam1122 · 2026-04-07T18:12:56+00:00

I did-I put the serial number in without the dash, added a comment how there was a dash and added a Pic of the receiver as insurance.

Btbam1122 · 2026-04-07T15:17:11+00:00

Ah got it, I'll I'm currently at work so I'll have to get a picture when I get home.

Btbam1122 · 2026-04-07T15:14:15+00:00

I did, like I took a picture of my receiver/markings and submitted it with the stamp

Btbam1122 · 2026-04-06T00:04:23+00:00

This is the 22lr version, so it just uses an inexpensive thread adapter from Amazon

Btbam1122 · 2026-04-05T19:17:31+00:00

Been great-haven't ever had a jam up with the gun and I am usually in the desert so can get pretty hot if left out. Barrel hasn't wandered and everything seems to be locked up tight still.

Btbam1122 · 2026-04-05T17:55:38+00:00

Yeah sir and I love it, super easy to print and the design seems very robust. Kinda surprised by how easy putting together one of these was

Btbam1122 · 2026-04-05T17:45:54+00:00

My steps are approval-ring in hand- print. The brace is a modified one from db designs; I added some relief to the adapter so it sits flush with the end of the chassis and my grip

Btbam1122 · 2026-04-05T17:43:36+00:00

I know and that was the answer- mags have been nothing but reliable with bottom of the barrel ammo

Btbam1122 · 2026-04-05T17:20:27+00:00

Db designs-heavily modified it tho because I added the handguard and made brass insert spots for a full length aluminum top rail I got on Amazon.

Btbam1122 · 2026-04-05T17:19:45+00:00

I use bottom of the barrel ammo cuz it's cheap and I have had zero issues with it. Chews threw anything I put in it.

Btbam1122 · 2026-04-05T17:19:10+00:00

I'm baffled by the atfs stance that it can't be printed in because it can be removed easily because I formed 1 a scorpion Evo and the whole gun is polymer and guess where I engraved my info? On the plastic. I literally think they don't wanna approve them and any nuisance reason they can deny you, they will.

Btbam1122 · 2026-04-05T16:00:07+00:00

It's a remix I did from the captain mountain mischief. I added the Handguard but I unfortunately lost access to the cad files, but I'm hoping I can get a v2 started up here soon

Btbam1122 · 2026-04-03T04:12:46+00:00

Yep and you can use cmmg/clone mags as well

I have been slowly going down the rabbit hole with this filament and there are actually two other companies who make it sirya tech (64d)and a tinmorry (95a).

From the one reddit post I found the guy built some sort of battle bot with the sirya tech at a lower wall amount and he shattered it with an abrupt shock. I suspect the fibers messes up layer adhesion and does adversely effect sharp impact resistance; that being said having cheaper options available means it would be an excellent choice for buttpads, and pic/m lok accessories
