    Clarification on CZ Shadow Target legality?

    in IDPA Shooting

    Posted · Edited by ChaseMarshall

    First, let's define the pistols we are talking about. I will only mention the differences that we are concerned about here so that this info can be applied to other pistols:

    CZ SP-01 shadow - full railed dustcover & stock sights (ssp & esp legal)

    CZ SP-01 Shadow target - full length railed dust cover & slide milled to accept LPA adjustable rear sight. (Not legal in any IDPA division)

    CZ75 shadow - short dustcover & stock sights ( ssp & Esp legal)

    CZ75 Shadow target - short dustcover & slide milled to accept LPA adjustable rear sight. (esp legal)

    SP-01 = full length railed dust cover

    Target = slide milled to accept LPA adjustable sights.

    In SSP you cannot mill the slide for LPA rear sights (8.2.1.3.1.) Therefor all "Target" varieties are illegal, both SP-01 Shadow Target and CZ75 shadow Target.

    In ESP you can mill slides for the LPA rear sight but you cannot have a full length dust cover (8.2.2.3.1.) The CZ75 shadow target is legal because it has a short dustcover.

    The SP-01 shadow without a milled slide for the LPA cut is also legal in ESP using the SSP into ESP rule (8.2.2.1.7.)

    I hope that helps to alleviate any confusion.

    For the record, I think all these rules are dumb.

    TTI basepads in Production - USPSA

    For esp I use the speed shooters specialties base pads with the "toe" ground way down. I have no idea why they added all that unnecessary aluminum. I hated the way they fit the hand and with my pouches placed pretty close I have inadvertently dumped the mag behind the one I was drawing on the ground.

    Using a 2011 in IDPA

    8.2.2.3.1.

    Steel dust covers and rails over 3.25” (as measured from the rear of the slide stop pin to the

    most forward portion of the dust cover or rail) are not permitted.


    My mistake, Rear of the slide stop pin, not the trigger guard.

    I know a Full-length dust cover on a 5" gun is not allowed even if it its from factory unless you are using the SSP itno ESP rule (8.2.1.1.7.) which would not be applicable to any 2011.

    I'm not sure about on a 4" gun. The rule is the steel dustcover can't be more than 3.25" measured from the front of the trigger guard. (8.2.2.3.1).

    Also you would be OK with a bull or cone barrel on a gun with a barrel of less than 4.25" (8.2.2.2.21.)

    I'm not sure why you would want a 4" gun over a 5" gun for this game though. You could always get an Eagle with a bushing barrel.

    Adjustible gas blocks with Full weight BCGs & LW buffer

    Thanks for all the input guys.

    I'm going to get the adjustible gas bolck and tune it for the standard (3 oz) buffer and then I might look at the Taccom LW buffer later. Does the Taccon LW buffer system come with the Spring and a Nylon (?) spacer? Thats what it looks like from the initial product anouncment thread here on the forum. Iif I'm correct the spacer is for Rifle length buffer systems?

    Thanks,

    BitchinCamaro-"What are you trying to accomplish"

    This is always a good thing to keep in mind. The original intent of the adjustable gas block was to address the over gassing. When this is addressed I can put the ST-2 buffer back in the rifle it came from. Now I have the option to reduce the reciprocating mass with a LW buffer.

    Is the combined weight of the buffer & BCG all that matters? Do they need to be reduced in tandem? What weight is a good place to be?

    I started throwing stuff on the scale :

    Rainer arms match grade Nickel Boron BCG = 11.7 oz

    Spikes ST-2 buffer = 4.1 oz

    Current total mass = 15.8 oz

    Carbine buffer = 3 oz

    I opened up a standard carbine buffer and got:

    Empty buffer = 1oz

    Each weight = ~.6 oz

    Plus some little rubber disks.

    So I can run my current BCG with an empty buffer and be at 12.7 oz but I might have some carrier bounce like Therealkoop experienced.

    If I ran one weight (with a spacer made of hose) I would be at 13.3 oz.

    Or I could run 3/4-1oz of #8 lead shot in the buffer for a dead blow effect.

    Any thoughts?

    Adjustible gas blocks with Full weight BCGs & LW buffer

    B45C22, there is a second roll pin that runs parallel to the barrel on the Syrac gen II that retains the dentent spring and ball. I will definitely be going with a set screw type gas block over the clamp on for the ressons you mentioned. I'm certainly not set on the syrac.

    I like to SLR DA7 gas block as well. I will look into that.

    I have a JP adjustable on my LRP-07 and it is cool but it can be hard to adjust under the handguard and I want the click adjustments that the detents offer.

    I appreciate the feedback on the gas blocks but I was really looking for some feedback on the buffer weight options. Does anyone have experience with light weight buffers and full mass BCGs? Will I need to change spring rates? Can I offset a full mass BCG with an extra light buffer?

    Thanks,

    Chase

    Thanks for the info on thre Syrac, I had read alot of good reviews on it and the reason I was going to go with it vs some of the other is the fact that it has a detent to hold your settings.

    All the others are pretty much the same, I could easily drill and tap a hole in the side of my current low profile gas block for a set screw.

    What do you mean "it siezed"? It has a small roll pin on the side that holds the dentent spring and ball. Seems like you could drive that out and access everything.

    Did you have the Gen 1? The first one with the little plunger you had to press to adjust looked like a poor design.

    Just trying to make an educated purchase, $109 is high for a gas block so if it is no good, I'll go another route.

    Thanks,

    Chase

    I am going to purchase a Syrac Gen II adjustible gas block for my 18" midlength AR. It is a bit over gassed right now and I would like to tone it down.

    I have some questions regarding Light weight bolt carrier groups and Buffer weight combos.

    I currently have a full auto style Rainer NiBo BCG and I have put in a Spikes ST-2 (4.3oz) heavy buffer (from another rifle) in attempt to counteract the over-gassing. I have no intentions of buying a LW BCG at this time but I am wondering if I can get away with a super light buffer to decrease the recipricating mass and have similar results.

    The way I think about it it seems like the BCG and Buffer move together. Would having a Full mass BCG and a light buffer play well together? Do I need to change buffer spring weight?

    I was thinking about taking all the weights out of a standard carbine buffer (3oz) and running it empty (giving me a .5oz buffer?) or trying the Taccom UL buffer (don't know weight)

    From Taccom website : "Designed for the AR15 Rifle or Carbine Buffer tubes, our UL Recoil System works with standard weight or Light Weight STEEL* carriers and adjustable gas blocks**.)

    What are your thoughts.

    Thanks,

    Chase
