Taccom Delayed Blowback buffer system

  Taccom has come on the market with a delayed blowback pistol caliber carbine (PCC) buffer. We discussed it on Episode 282 of the Gun & Gear Review Podcast. I was intrigued by the way it functioned, so I talked with Taccom and they sent one to review. Taccom has been really coming on strong with products for the 3-gun market.

  As mentioned, this system is a delayed carbine buffer system for AR pattern PCC’s. How do they delay blowback in a straight blowback system? Taccom uses rare earth magnets, that’s how. The magnets literally delay the blowback, for a split second. This results in lowering the pressure used to send the bolt backwards, thus reducing the recoil impulse. It is nice to see Taccom thinking outside the norm with this system.

  I installed the Taccom buffer system in a 9mm PCC. As noted, if you have a bolt with a weight in it, you must remove the weight for the system to properly work. Since the system is self contained, you can also opt to remove the buffer retainer and spring. I used it both ways and it made no difference. It is made to be used in Carbine buffer tubes, not rifle length tubes. Being that it uses a flat recoil spring, and is self contained, it does reduce some of the “twang” noise associated with the standard AR buffer/spring/tube system.

  After first installing the delayed buffer system, you immediately notice some differences. First up, it is quite a bit harder to charge the system. The magnetic delay system is really noticeable. It is not a problem, kind of like the difference between pulling the slide back on a 9mm pistol versus a .22lr pistol. Next is the “Short Stroke System”. With the delayed system, the buffer doesn’t allow the bolt to travel reward as much as a standard recoil system. This makes it not possible to use the bolt hold open. I really disliked this function, as I couldn’t lock the bolt back during matches, or when the gun runs out of ammunition in the magazine. Besides those, everything else works the same as a standard AR.

  I can see the benefits to the Taccom delayed buffer system. It definitely reduced the recoil impulse, making it easier to get back on target fast. I ran a bunch of different types of 9mm ammo through the system. Practice ammo would sometimes cause the system to short stroke, as the system was not quite travelling all the way to the rear. This was pretty common. Sometimes it would load a round but not reset the hammer, other times it wouldn’t even load a round. It did this with both the Stern Defense adapter, and the Endomag

  The Taccom system is lighter than what I previously was using. My stock system weighed in at 8.3 ounces. The Taccom weighs in at 7.3 ounces. So I did save a little over an ounce while reducing felt recoil. PCC’s tend to be heavier due to all the moving mass in the blowback system, so an ounce could possibly make a difference for some people.

  Taccom is innovating with this delayed buffer system. I would like to see it with a bolt hold open. It does delay the system and reduce recoil. So if you are looking at pistol caliber carbine stuff, or 3-gun specific parts, go check out Taccom.
