  1. I installed the 140% recoil spring in my gun and immediately the gun start plooop BBs instead of shooting. Anyone know why this happens? I just put in the regular spring and it seems to work fine. I just want to know why it does that.

     

    Until you get the reinforced hop up and bucking, the 140 spring will feed the BBs past the hop unit and into the barrel. That's why they just roll out. Our shop CQB-R blew up the rim of the stock hop chamber and we are now waiting for our reinforced unit so we can use our 140 spring again.

     

  2. does anyone know how to use front strap checkering files?? I know they are meant for RS 1911's but im thinking they would work. Saves the trouble of getting a nova frame.

    You do realize that hand-cutting checkering at 30 lines per inch is a very good way to go blind? You can learn the basic technique from pistolsmithing books, but they may not be in depth enough unless they are dedicated textbooks.

  3. Tuner Guy is a genius GBB builder. He has done a number of awesome guns and was a member of this forum for a while.

     

    However, several months ago he took a bunch of orders (including a custom build for me) and then completely disappeared scamming a number of people (including me).

     

    I have a huge amount of respect for him as a builder but as a person he's a scammer and a leech.

     

    [i guess that I am slightly biased since he jilted me out of several hundred dollars]

    Tunerguy is dishonest. He tried to present himself to me as a customer when in fact all he was trying to do was pick my brain regarding my gun building techniques and my favored parts combinations. After putting together a virtual parts list for him so that he could keep track of his expenditures, he appears on these forums looking for said parts so that he could build the same gun for HIS client. He's far from a genius. Anybody can build a gun that looks clean in photos and shoots reasonably well. A fully built gun that will retain it's accuracy and performance over thousands of rounds with only routine maintenance is another story. Back to this thread. My MAGNA xcelerator LIMCAT will be coming home. I'll get my pics up as soon as I finish restoration.

  4. I love your infinity, twin cam

    very very very nice

    Thanks. It took forever to find a magna 6 inch, and then one day it just popped up and I was asked to build it up. In the days before the flood of aftermarket barrel locks, I fabricated my own. Same goes for the front sight. I fabricated that one from nickel then gave it a gold bead to enhance the sight picture in low light.

  5. Question: Is it possible to attain 460 (+/- 50) fps using 134a with this rifle? I'm informed that the action is somewhat flimsy and may not be up to continuous green gas usage. Or can I use green and just put the PCS to minimum?

     

    it's an m700 action. the same action in the m24 was good for 500 fps on 134a. a good idea if you want to use higher powered gases is to purchase a g&g powerpack which will cover the bolt assembly and two magazines. be warned tho that this setup on red gas will put you into extremely high fps territory.

  6. Building this gun for Hitman wasn't as much of a hair pulling experience as the PRIME kits. There seem to be some quality control issues at Guarder as I have had to actually sift through large numbers of these kits to make sure I got one with perfectly straight lines. The last batch I received had quite a few imperfections, but at this price, what do you really expect? At least now I know why the kits by PRIME cost so much more.

  7. Sounds like alot of work, is it worth the effort? Any chance of a more indepth review of the finished article?

     

    It was a great deal of work, but there's no denying the appeal. If you have the money and spending it is not an issue, then yes, it is worth it. I took the finished product to several marines who then proceeded to insert loaded 9mm magazines into it. That should tell you something. The balance is superb and the weight of the gun is reassuring. Accuracy and consistency are much improved over stock. The real world testing will be in the crucible of combat later this evening. I will field test it for the owner to make sure that there are no hidden bugs. I'll report on the results after the game.

  8. For those of you who complain that the TM p226 is too plasticky, here's something to ponder on. Ever wonder what it would be like if you had one in full metal? Well, I was recently commissioned to build one as a bday present and didn't expect this much work, though Prime kits are always far from easy.

     

    The kit itself is beautifully made and looks great in the box, but the big problem is getting everything to fit with the stock internals. If you want to attempt this yourself, all I can say is Godspeed.

     

    Because of the complexity of the sig design, there are springs EVERYWHERE in this gun and if you are not careful, you will lose them. Once you strip down the donor to bare frame, the fun really begins. Placing the original subframe assemblies inside the new frame seems pretty straightforward until you check the height of the frame rails. The rails on the subframe sit .3 to .4 mm higher than the rails on the grip frame. These must be handlapped to the proper height. If you do not have the proper jig and the tools to "deck" the rails, forget about it.

     

    Other various pin holes must be enlarged to accomodate your factory retaining pins. The magwell must be carefully sanded, otherwise mags will not drop free. There are too many items that need the careful attention of a gunsmith so I will repeat: this is not for novices. The slide isn't too bad for transplanting internals, but the real problem is fitting it to your frame as the tolerances are extremely tight. A caliper is a must.

     

    Internally the gun sports springs by RCC, RCC cylinder bulb, tightbore by KM, and alot of massaging by me. I only have one pic of the gun so far, but it should give you an idea of what is possible with time and money. As for performance, with this level of gas flow upgrades, performance is modest at 325 fps. More is attainable, but what is important is consistency. It absolutely refuses to drop below 325 until there is next to no gas left in the mag, or you fire off more than a ten shot full reset string. Here it is.

  9. quote:

    The call then went out to the engraver. Engraving is a bit of a lost art in the Philippines, and there are very few who are recognized as masters of the art. Constantino Petere was kind enough to answer the call. It’s not well known except among jewelers, but this man was responsible for the bulk of engraved jewelry in Imelda Marcos’ collection. After suffering from a stroke, Constantino was unable to work for many months, but eventually recovered. He no longer accepts work for ornate engravings, but he was kind enough to do me this favor.

     

     

    I have to apologize to Mr Petere. After talking to my wife, she corrected me. His full name is Constancio "Nonoy" Petere. He's my brother in law's godfather and a good friend of my father in law, so it wouldn't be good to let this go uncorrected.

  10. >> plating in 24k gold

     

    It's remarkable, but did you REALLY leave the KJW grips on? Even if you didn't want wood, some genuine Beretta logo'd ones would have looked much better.

     

    Still, that's easily addressed and the real work is in the frame and slide, which (as I said, but will say again) are remarkable!

     

    BTW, what's the barrel like? Plain gold?

     

    Cheers.

    The top of the barrel is also engraved similar to what you see on the frame. The owner will be changing the grips later as we had already gone over budget. I haven't seen the gun since I built it, so I'm not sure what grips he ultimately replaced them with
