Review of Polished Tapco G2 AK Fire Control Group<\/strong><\/span><\/p>\n

BY<\/span><\/strong><\/p>\n

\u00a0Mark E.<\/span><\/strong><\/p>\n

I decided it was time to upgrade the fire control group (FCG) on a rifle of mine before\u00a0Christmas. I bought a new, TAPCO G2 from Dinzag and had them do the Polishing\u00a0Service on it. And I had wanted to add some more spare parts, so I decided to remove\u00a0and keep my original FCG on the Yugo underfolder, 7.62x39mm, rather than sending that\u00a0in for polishing. I ordered up a new FCG Retainer Plate, too.
\n*** Just a quick note on the FCG Retainer Plate, shown below. While this write-up will\u00a0focus on the polished fire control group, it was a snap to pop-in this Retainer Plate. I\u00a0came across info a while back that the FCG \u201cretaining wire\u201d was a weak point in the AK\u00a0system. If it came loose or was compromised, the trigger or hammer pin could work\u00a0loose and take the gun out of service in a hurry. So, I added this new FCG Retaining\u00a0Plate at the end of my FCG installation, instead of the original FCG retaining wire.<\/p>\n

\"1-FCG<\/a>
\nSo, on to the polished TAPCO G2 FCG that I received from Brian at Dinzag. Here\u2019s \u00a0what it looked like after I opened the package:<\/p>\n

\"2-FCG<\/a>
\nYou can see the surfaces that Dinzag polished above, with the red arrows. Notice that\u00a0this G2 trigger is a \u201csingle hook\u201d so besides the hammer face itself, only ONE SIDE of\u00a0the hammer is polished to match the contact area.<\/p>\n

PART \u201cA\u201d<\/strong><\/span><\/p>\n

A quick summary of the preparation to get to the point at which you can remove the\u00a0FCG are:
\n\u2022 remove the magazine, if present<\/strong>
\n\u2022 verify and double-check that the chamber is empty (visual & by touch)<\/strong>
\n\u2022 remove the top cover<\/strong>
\n\u2022 remove the bolt\/piston assembly<\/strong>
\n\u2022 remove the safety\/selector lever (right side of photo below)<\/strong>
\n\u2022 and then\u2026grab a small cable tie (a.k.a. zip-tie)<\/strong>
\nOne tip that I learned from Jim Fuller of Rifle Dynamics, was to make use of some\u00a0plastic cable \u201czip ties\u201d when working on an AK FCG. Specifically: use one to hold the\u00a0sharp little ends of the hammer spring in place while you work. If you\u2019ve ever done work\u00a0on any AK-variant, and have messed with the hammer spring without this tip, you may\u00a0already have scars to prove it.
\nBefore you remove the FCG Retaining Wire (or retaining plate, if you already have one),\u00a0pull up BOTH hammer spring ends, and secure behind the hammer as shown here:<\/p>\n

\"3-zip<\/a>
\nAt this point, I could proceed with the follow steps: <\/strong><\/p>\n

    \n
  1. Remove the old stuff and install the\u00a0new stuff (please excuse this highly technical terminology)<\/strong><\/li>\n<\/ol>\n

    PART \u201cB\u201d<\/strong><\/span><\/p>\n

    \u2022 Remove FCG retaining wire or retaining plate from inside the receiver<\/strong><\/p>\n

    <\/strong>\u2022 Push out BOTH the trigger pin and the hammer pin<\/strong><\/p>\n

    \u2022\u00a0<\/strong>Remove the old trigger<\/strong><\/p>\n

    \u2022 <\/strong>Remove the old hammer with the hammer spring (cable tie still in place)<\/strong><\/p>\n

    \u2022 Remove cable tie<\/strong>\u00a0and then carefully put the spring on new hammer<\/strong><\/p>\n

    \u2022<\/strong> Secure hammer spring to the hammer and add new cable to tie to hold in place<\/strong><\/p>\n

    \u2022 Install new trigger and insert trigger pin<\/strong><\/p>\n

    \u2022 Install new hammer and insert hammer pin (same as trigger pin in most AK\u2019s)<\/strong><\/p>\n

    \u2022 <\/strong>Cut and remove the cable tie<\/strong><\/p>\n

    \u2022<\/strong> Guide the tips of hammer spring back into the original position<\/strong><\/p>\n

    \u2022 <\/strong>Install FCG retaining plate or retaining wire<\/strong><\/p>\n

    \u2022 <\/strong>Install safety\/selector lever<\/strong><\/p>\n

    \u2022 <\/strong><\/em>Admire the shine of the polished surfaces \u2013 especially on the hammer!<\/strong><\/p>\n


    \n<\/em>Here\u2019s what it looks like before and after\u2026<\/p>\n

    \"4-before<\/a>
    \nYou may be able to see the retaining WIRE in the bottom of the BEFORE photo \u2013 it is\u00a0wrapped around the bottom of the selector lever shaft. And you might be able to make\u00a0out the retaining PLATE in the AFTER photo. \u00a0I performed a trigger function check both before and after I added back in the bolt\/piston\u00a0and top cover. All was good, so\u2026on to the fun part \u2013 the range test.<\/p>\n

    Conclusion<\/strong><\/span><\/p>\n

    I\u2019m putting my conclusion here, out-of-order, because of the way I felt at the range after\u00a0only a few trigger pulls. I knew immediately, that for me and this particular AK:\u00a0The polished G2 FCG from Dinzag is a winner!\u00a0<\/em><\/em><\/strong><\/p>\n

    Range Test<\/span><\/strong><\/p>\n

    I also re-mounted a low-end 1x red dot before this range test. So, I decided to throw 3\u00a0quick shots down range at 50, knowing my red dot might be off some, which it was. I\u00a0took these three shots without making any windage or elevation adjustments. I wanted to\u00a0get an idea of consistency given the impact of a smoother trigger on this 7.62 firebreather.
    \nI was VERY happy with the results. I used higher quality brass ammo before feeding the\u00a0AK some Wolf later on. This what I used to start with\u2026<\/p>\n

    \"5-range<\/a>
    \nAs they say in Golf, I guess equipment does make some difference!
    \nThe photo below shows the first three shots at 50 yds (photo top, right = middle of paper\u00a0target; big diamond). After a few tweaks for ” high and left,” I let loose at 100yds with\u00a0rest of the American Eagle brass and then switched over to Wolf 124gr Hollow points.\u00a0Also shown is example at 100 yds, while I was walking-around all four corners of the\u00a0paper, taking one shot each (photo bottom, right = the small paper target diamond).\u00a0<\/em><\/em><\/p>\n

    \"6-targets<\/a><\/p>\n

    I wanted to move to the 200 yd range before I left, but was out of time, so I called it a day.<\/p>\n

    Final Thoughts<\/strong><\/p>\n

    One advantage of having a much-improved trigger was that I was able to perform a\u00a0double-tap on my AK that was like nothing I had been able to do before. In fact, my\u00a0Yugo trigger now feels like a tuned pistol! I\u2019ll put it this way\u2026if I had not been at a “safety nazi” public range, I would have tried some 3-4 round bursts, or should I say \u201cvolleys.\u201d My Boss and colleague here at HCS may have to help me out with a place for that next round of testing….only time will tell.\u00a0Even if you like your current trigger, you may still want to replace that FCG retaining\u00a0wire ($7 plus shipping for a new Retaining Plate) as a starting point. And if you have not\u00a0tried a polished FCG, give Brian at Dinzag Arms a try guys, (check out HCS’ LINKS) he not only can set you up with a new trigger, but an entirely brand new modified weapon that will sing like the Vienna boys choir every time you pull the trigger!<\/p>\n

    Keep your trigger pull smooth and your reset short…and STAY DANGEROUS!<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
