Taccom Delayed Blowback Recoil System

[SingInTheRain]

@TRUBL  Any status when the extreme feed 5.25" barrel will be back in stock?  I received the DBRS and ESSB but now the matching barrel is out of stock

[Ontos]

Also? How about that pinned and welded 13.5”?

 

Building a back up before Nats.

We should have them back in stock ready to ship next week.....everythign is out for plating, as soon as we KNOW when they are coiming back to our shop we will have them available for pre-order. We are also working on the 13.5" and a new 10" barrel with a pinned and weld brake as well......about 3 or 4 weeks for those

I got to shoot one and inspect it. Amazing difference, totally changes the recoil impulse. If I get chance we've got the mantis we will plot old vs new. Greatly lessened the time, used be three parts, ignition, bottoming buffer and bolt closing. With reduced math that last two parts are virtually  gone.

For those using the buffer, did you remove the buffer retaining pin or left it intact?

[cking]

You have to remove it

[TRUBL]

We do recommend that you remove it.....it mmmmmmmight work with it installed, but it's best to remove it

It's upgrade time for my USPSA/SC PCC, so I want to make sure I get this right... if I buy the ESSB+DBRS combo for my DDLES Glock lower build, will I get all of the following?

1. Short stroke

2. Delayed blowback

3. Functioning LRBHO

I haven’t personally tested that exact combo but a definite yes to the first two items and you should have LRBHO as well with the extreme bolt.

Funny timing - I just talked to Tim @ Taccom about this very thing. He said yes, 'maybe' - that it was upper/lower dependent. I'm running NFA upper/lower and he said that should work fine. Unfortunately, he's out of stock on that bolt and it doesn't sound like they're coming back in stock quickly.

Yeah, compatibility is always a thing with AR-9s. I get that.

I did a lot of development at another company for what is probably one the most reliable 22RF uppers on the market today and that bolt, does not have a feed ramp......it has a radius to the flat on the bottom.....what that does is allows for the hammer to completely cock sooner...

Tim

I’d like to know more about this. Shooting more .22 LR at steel these days. What company, if you don’t mind my asking? PM if you prefer. Thanks. 

[erwos]

I put in my order for the ESSB+DBRS today. Looking forward to taking it for a spin once the 'rona lockdowns around here are lifted.

Finally made it out to the range to give it all a try. FCG was a Hipertouch Competition trigger, barrel is a JP Supermatch.

 

Cycling was indeed much faster, with what I think was significantly less sight bounce. Unfortunately, I also got some bursts followed by misfeeds, I think due to hammer follow. I am going to talk to @TRUBL and see if there's something I can do. Otherwise, gonna switch back to a traditional BCG+buffer system to isolate the source of the issues.

Follow-up: talked to the man, gonna change to the red springs in my Hipertouch and see if that makes a difference. Very impressed with the level of customer service!
