Startingover Posted September 22, 2018 Share Posted September 22, 2018 Nice. I was hoping to get mine on tomorrow. But I should probably wait, because we have a 2 gun match on Tuesday, and I don't know if I will have time to get it sighted in. Link to comment
JDIllon Posted October 1, 2018 Share Posted October 1, 2018 I've been using the small Tacom on a PSA 16" upper and it seems to help. I wish PSA would change to 1/2X28!!! threads. JD Link to comment
sweatpants Posted November 2, 2018 Share Posted November 2, 2018 Any updates from the guys with the new Taccom CF/braked barrel or T&N Cannibal users? Link to comment
JsK Posted November 2, 2018 Share Posted November 2, 2018 MBX now has a light weight version of there 14.5 with the comp pinned and welded. There comp is one of the few that doesn't just look like a recycled 223 brake. Got mine yesterday, full length barrel 17.5 oz Link to comment

My 13.5" with the pinned brake still works great. I probably have 1k-2k rounds through it now. Had a couple magazine problems last week with the 57 round magazine but I just got a new MBX spring and it should be good to go. Link to comment

I have the Cannibal on a 16" 9, Wanted it to show me something but it didn't. It actually seems to be quiet. I had 3 re shoots at a recent big steel match. RO's were experienced PCC guys so they were not the problem Link to comment

RO's were experienced PCC guys so they were not the problem I've had this problem with both the Venom brake and JP brake previously mentioned on this post; between a 16" barrel and running reloads that aren't as powerful as factory ammo, PCCs can be fairly quiet and setting up a shot timer just right so it records your shots and not people in the next pit is a pain, it seems to be a growing issue. Of course RO could run almost right on top of you but that could get bothersome and unsafe even. I had 2 re-shoots at my last match because of it. Although if you run full power factory ammo the comp/brake would be doing its job more I would imagine with the gasses being produced. Link to comment

I feel like this barrel has been sold out for ages. Link to comment

I'm liking mine a lot. Nice and nimble on transitions, accuracy has been spot on. Don't really know if the comp is having much effect, but I'm fine with it. Link to comment

I've managed to mount the barrel in an upper, and break in the barrel. I'll have more feedback if (or when) it ever stops raining out here. Link to comment
mellino19 Posted November 29, 2018 Share Posted November 29, 2018 Hey all, I saw that MBX has a new lightweight barrel with their new style comp on it. Does anybody have any experience with this set up? I know I've mentioned the Venom brakes in the past but given the nature of PCC especially with reloads, the MBX brake would seem to be ideal with how the direct gas, or maybe even the PWS comp however I'm super curious on the MBX barrel and comp setup since I can't leave anything alone.

It made a sublte yet significant difference on mine: Look at the .308 hyrdo buffer and red spring: with and without a comp. It is night and day. Afterward I slowly enlarged the ports with a drill until the rifle shot totally flat. Once I got the gun dialed in, I shot it one last time without a comp before chopping the barrel down to 14” and doing a pin & weld. The muzzle rise came right back. It’s doing something to kill that last little bit of muzzle rise. Edited November 29, 2018 by MemphisMechanic Link to comment

Knocks down full size poppers out to 20 yds. I'm happy. Link to comment

Oh I completely agree that it doesn't make a HUGE difference but a very noticeable difference can be noticed. Dot tracking and recoil impulse matters tremendously in a division so fast.

Softness is irrelevant to winning. I’m a grown man shooting a handgun off my shoulder. Give me a hard punch to the shoulder, but the ability to rip a .14 split off at 15 yards and have the holes tightly inside the A because the gun is dead flat? I’m down. That’s what I did. A lot of what we do in PCC is like Open; making the gun hit you quite a bit harder, but it cycles flatter. Short-stroking them is a good example of this.

I have one coming Monday, but to be honest I bought it more for its 16" overall length with a pinned brake for sound pickup purposes mores than expecting the brake to really flatten out the barrel. I got the MBX because I somehow bent the Taccom Featherweight that I had that had the same sort of overall length with a pinned brake. Thing is, I see the whole brake thing as sort of either/or.....in that you would probably notice more effect if you loaded some hot ammo, but then you'd also be increasing your recoil and maybe dot bounce as well. But then if you load down your ammo power, you get less recoil and can maybe tame the reciprocating mass, but then there's essentially nothing going through the brake. For me the brake has most value of diverting sound enough for the timer to pick up in competition, especially outdoors. And of course, it looks cool too. As Memphis points out, I guess recoil isn't a big deal as long as it's straight back and the muzzle stays flat. But I'm just shooting regular factory ammo for now.

But a litle extra stabilization of the gun goes a long way when everything else has been optimized. This. I run 2-completely different PCC's & have pretty much since the start. Tuned with Taccom 3-stage short stroke buffers & loads. One is a ULW Taccom 5" barrel with aluminum tube/CF handguard. Weighs a little over 5#. Second is a JP 14.5" with pinned JP Tac comp/CF handguard @ about 6.5#. Although the recoil is not much different or dot movement t I find with the lighter one I tend to swing faster and sometimes past being so light & fast. The heavier JP with the comp at the end tends to settle quicker and be a more stable especially for longer more precise shots. gerritm Link to comment

I will agree that top competitors need every little bit they can get, I also think that the little bit they get from a comp means little if they win or not. I did not realize you are so high and mighty to think a lowly b class shooter cannot be savy about the gun they shoot. Link to comment

Countless posts trying to figure out “how to make a PCC shoot more softly” give lie to your attempt to classify them as having worthwhile advice. Flatness matters. Softness doesn’t. Link to comment
