Taccom’s Heavy PCC Carbine Recoil System

Taccom, known for their competition oriented offerings including shotgun shell caddies, ultra-light weight buffer systems, and a plethora of magazine extension kits, has turned their attention to the red-hot pistol caliber carbine market with their latest buffer system, the Heavy PCC Carbine Recoil System.

Almost all pistol caliber carbine systems are blowback operation based, which means they require weight to offset the recoil forces generated by the cartridge to function correctly. Given that most PCC’s are AR-15 based, the additional weight has to come from the buffer, presenting additional issues.

  1. The standard AR-15 buffer is designed around a rotating bolt that sits forward of the carrier body. When using a standard carbine buffer, PCC’s have a tendency to break bolt-catches. With the extra travel, they have more force and slam into the catches.
  2. Difficulty getting to the weight required to slow down the action. “H3” buffers (those with 3 tungsten weights) only get to 5.4 ounces.

The Taccom Heavy PCC Carbine Recoil System looks to address both of these. The primary buffer weight is solid billet clocking in at 6.2 ounces and includes a spacer to take up the additional travel space in a common carbine receiver extension.

Those interested in trying the system out can pick it up directly from Taccom on their website. Retail pricing is set at $29.95, which is substantially less than the base cost for an H3 buffer.

    Ehh. Kaw Valley makes one at about 7.5oz for $35 and it also has the included spacer.

    I personally went with the $50 KAK 10oz 9mm buffer (which also has the spacer)

      I came across those same 2 options when writing up my parts list for my pistol build (that I have yet to actually build). How did that KAK work out for you?

        I get the KAK in this week. I’ve been running the KVP one for a while and it’s great. I run suppressed and I think a heavier bolt should keep the whole setup quieter in theory.

    A couple years back I used a VLTOR A5. The length is perfect, no spacer required, and the h4 is just shy of 7oz. There are a lot more options now. The A5 had worked well enough that I’ve not tried any of the heavier options.

    A solid buffer is not going to be a buffer anymore, just a weight. Without the “buffer” you’ll have a lot of bolt bounce. Might not be an issue with semi-auto guns, but will most likely cause issues with MG’s.

      Correct. KAK sells a 10oz actual buffer with tungsten weights. May be a good option.

    I went with the Spikes 9mm buffer that’s actually a longer buffer, so it shortens travel without needing a spacer. I don’t have to take out the recoil spring, which isn’t a big deal, but it’s one less thing to do. It was $50, though, and I wish there had been something like it at this price point.

    It still beats up the bolt catch because reciprocating mass is so heavy. It hasn’t broken the catch for me, though, it has actually bent the lower receiver in front of the bolt catch so now the catch wobbles a little.
