  1. Due to the front lug and sight on the M4, its a lot easier to install a KA-1212 or KA-1212BR on an extended choke tube. We usually use a cylinder choke and do a slight reverse-jug on it for better patterning. Not tooting our own horn here, but there's nothing on the market right now that performs as well as the KA brake/suppressors do. Between the improved patterning, reduced recoil, and near-elimination of muzzle flash, it is probably the most effective upgrade for a shotgun. The ability to shoot faster and further without flash is a helluva advantage for the scattergun
  2. Any new gun is going to have a break-in period before it will run smoothly (and eat lower power loads). The surfaces have to smooth out and the springs have to take a set. As far as ammo goes though, use Federal bulk-pak, its a little hotter and runs in most semi-autos very well. Winchester ammo is usually a bit doggy in gas-operated semiautos.
  3. We can refinish your barrel and mag tube for about $75 including return shipping. Parkerizing + Duracoat or ceramic
  4. We do forcing cone work, but most Benelli barrels are chrome-lined and that really makes doing any reaming work more of a PITA than its worth. For the conversion we just need the barrel and the mag tube, we built the tooling to install everything just as it was on the factory barrel, so your sights will stay the same (or damn close) after we relocate it.
  5. We don't do much work with chokes here, I'd contact a smith that does a lot of work on sporting/hunting shotguns, they'd be a better authority on the subject. Most of what we deal with is LE/HD guns where 99% of the barrels are cylinder bores. There's a smith named Mike Orlen out of MA (413) 256-1630 who is a guru when it comes to chokes, if it can be done he'd know how to do it.
  6. Hey, hadn't been on here in awhile but saw a ton of people were visiting our site from here so figured I'd check in to see what was going on. Just to clarify a couple things, we're not rethreading for chokes, the Benelli barrel is too thin to do that well. Were relocating items from the choked section of the barrel. If you look at the M4 barrel you can see how it flares out just prior to the choke tube, this is done to allow enough room to thread for the choke tubes. We've built all the needed tools to do the conversion right, and as long as we're doing several at a time it can be done quite reasonably (around $250-300). If you'd like to pay more, feel free to do so, we won't stop ya As far as not sending the barrels back until we get a copy of the ATF paperwork, you guys are right, it isn't required legally. The reason we require it is because we keep the copy of the form attached to the invoice for our records. The ATF has been watching us businesses that manufacture parts and modify parts a lot more closely in the past couple years (which is ironic since we don't fall under their jurisdiction), so we have copies of the forms for every NFA item that leaves here so we can document on our end that the part was for a legally-owned NFA item and that we're not making 'sawed-offs' for 'da homies' We do a lot of NFA barrel and component work on various guns, so obviously we want to make sure our stuff isn't falling into the wrong hands either or is being put together in an illegal manner by someone who just doesn't know better. For every NFA barrel we do, we probably fix two barrels that some knucklehead cut too short We are still waiting on a couple more M4 barrels to come in before we tool up for this next batch of conversions, so if you need to get yours done, let us know ASAP so we can get it added to the list. Also, we got a fresh batch of our KA-1212BR breaching attachments finished up. We can install one on your M4 barrel after the converting it to 14" for about $140 additional (includes the part and installation)
  7. Pick up a standard barrel and send it in, we can shorten it and bushing the sights/lug for you. You're going to have a helluva time trying to locate a factory 14" barrel unfortunately.

    Yes, as long as it is secured by one of the approved methods (i.e. hi-temp silversolder, brazing, welding, pin&weld, etc). One of our most frequent jobs is chopping Remington or Mossberg barrels down to 16.25" and adding a breacher for 18.25" OAL.

    Fortunately, we were able to fix it without having to scrap the barrel. The last 2.6" of the barrel were wrecked and our breaching attachments only add 2" to the barrel so we machined a custom extended version of our KA-1212BR that would add 2.75" to the barrel and radiused the bottom of it to fully clear the mag cap. We chopped out the bad section of barrel, resized the barrel lug and front sight to the right heights and had them TIG'ed to the breacher, then silversoldered the breacher to the barrel with a heat sink in place and reparkerized the barrel ass'y. It was by far the biggest PITA breacher install we've ever done, but it came out really nice and saved the customer from having to buy a new $900 barrel because some hack screwed it up. Warped didn't even refund the $200 he charged for the "job" and made a bazillion excuses. Moral of the story is this, if you F-up a customer's barrel, replace it instead of sending it back to the customer and acting like nothing was wrong. To f-up a job, not replace it or make it right, AND not refunding the $$$ is pure BS. If he had ripped us off like that we would have expensed out a pair of plane tickets to Illinois and collected a refund and reimbursement for the plane tickets in person. We've had to do it before, really surprises the **** out of sheisters when you show up on their doorstep

    It was soldered/brazed, we got to de-f*** the barrel for the customer. Instead of using a heat sink and a bushing like he should have, he piled brazing on till the sight and barrel lug heights were correct. Considering that an M4 barrel is about .050" thick at that point and he needed to shim the height about .110", you can guess how much heat was being dumped on that thin Benelli barrel. The barrel was horribly warped (including the alignment of the sight and barrel lug) and the temper of the steel was ruined, the barrel was so hard that it was a PITA to cut. This guy shouldn't be allowed to touch a gun without adult supervision

    He's now moved on to the 6.5 Grendel forums to peddle a different product/service. Seems like this guy is trying to be the next Todd Bailey
  12. Some lots of the Winchester AA's seem to be particularily nasty. Never had a problem with Federal bulk pack, just the AA's. Needless to say, we don't use AA's anymore. They dirty up semi's and stick in pumps, not worth the slight price savings
  13. Yup, 12ga with a 20.5" barrel and 7+1 capacity

    Warped, I saw some people having 'warranty' issues on this kind of SBS conversion work by some guy over at AR15.com. Any comments about how that chaps your butt to see people wrecking barrels and screwing customers? I'd really like your expert opinion on this, what do you think the customers should do? http://www.ar15.com/forums/topic.html?b=7&f=109&t=621929 http://www.ar15.com/forums/topic.html?b=7&f=109&t=610397

    Or this one? BTW, this doesn't look 'refinished', does it?
  16. We have a Legacy semi-auto that we use as a demo gun for our KA-1212. Eats up 7/8oz loads without a hiccup.

    Ammo for M4

    For cheap plinking, use the Federal bulk pak or the Remington HGL. The Winchester AA's are filthy buggers and you'll spend a lot of time having to clean crud out of your gas system.
  18. Yeah, the M4 is surprisingly easy to service. A lot easier to detail clean than the M1 IMHO. It doesn't take much to gum up the gas pistons though

    Would you care to comment on the following samples of workmanship? What do you think went wrong when someone converted these M4 barrels? Do you think the 'warranty' will cover a refund? Any idea who did them?
