    30mm or Mico Aimpoint for Tac Limited?

    in Rifle - Technical

    Posted

    What would be the disadvantage of using a Micro Aimpoint for Tac Limited?

    Is there a major advantage of the 30mm tubes over the Micro?

    I also assume that the 2MOA dot would be preferable to 4MOA.

    I've got a micro that I can use for Tac limited, but am also thinking about the Aimpoint PRO with 2MOA dot.

    Overtightening a muzzle brake?

    in Rifle - Technical

    Posted

    I guess the question is "how tight is too tight" before accuracy suffers.

    On the Surefire brake, it is indexed with peel washers to the 4-5 o'clock position before being tightened. Surefire specifies 30 ft lbs.

    In my case, it was around 60 ft lbs.

    I haven't shot the rifle yet, but will find out this weekend.

    How is everyone else putting their muzzle brakes on?

    Hand tight with loctite, or tightening from the 4-5 o'clock position with loctite or rocksett?

    maybe someone needs to do a Front Sight article on muzzle brake tightness?

    :-)

    Mick

    I just hand tighten my brakes with a couple drops of red loctite. A wrench will still get it off no problem but it'll never move otherwise. Over tightening a muzzle device is generally a bad deal.

    Can a muzzle brake be over tightened?

    If so, what problems can it cause?

    Installed a Surefire MB556K and using the supplied shims, got the brake to where it needed to be on the supplied indexing chart.

    Surefire says to tighten to ~30 ft lbs.

    This one would not index correctly until at least 60 ft lbs.

    DPMS Steel handle on sale now at DPMS for 59.95

    AR steel charging handles - yay or nay?

    Good idea. I peen the roll pins in by buffers after I had one walk out after a match. A little further and it would have bound up the recoil spring...

    Mick

    One other thing you may want to do is peen the end of the roll pin on each side just a little so it doesn't want to walk out over time. Make sure not to pinch the handle at that point and the latch still moves freely.

    Recieved the Brownells "steel" charging handle and it is actually a stripped DPMS aluminum charging handle with an oversized steel latch. They were incorrectly listed as steel.

    After I pointed that out to them, they sent me a steel DPMS unit and changed the description...

    Mick

    Thanks for the feedback.

    Brownells has a new steel charging handle at a pretty good price that I might try...

    Anyone use a half circle carrier in their AR?

    in Rifle - Technical

    Posted

    I'm building a new rifle and I have a couple of Colt half circle "Law Enforcement" bolt carriers lying around. These have the shrouded firing pin ramp like the M16 carrier, but the rear is cut to a half circle like the old SP1 carriers.

    Would using this carrier be akin to the lightweight carriers out there?

    Any potential issues going this route that anyone can see?

    Colt 20" A2 barrel for 3-gun rifle?

    in Rifle - Technical

    Posted

    I've got a new Colt A2 government profile 20 inch barrel lying around that I'm thinking of using for a lighter weight 3-gun rifle build. Plan is to add a muzzle brake, shave the front sight tower and mate it up to a 15" PRI handguard.

    Question is, has anyone successfully used this type of barrel for 3 gun matches? Will it be accurate enough, or should I sell it off for something else?

    M1A for 3-gun?

    in Rifle - Technical

    Posted

    Absolutely. Just ask Patrick Kelly!

    :)

    Mick

    Okay folks, before you get nasty with me, since I'm new at competition, would my Springfield M1A be applicable to a 3-gun competition? Yes, it's heavy, but it's damn accurate.

    Match barrel for 55 grain bullets ?

    in Rifle - Technical

    Posted

    I'm running the Noveske 18" with 1/7 twist on mine and all I use is 55gr ammo. Not a problem with accuracy.

    Gas block is a low profile pinned and can be had with rifle length or "intermediate length" gas systems.

    Maybe I just need to let you shoot mine to see what the rifle can really do. Lord knows I can't shoot for crap anyway!

    I had already purchased my DOH directly from Blade Tech. Now we know where they got the gun to make the mold!

    The only comment that I can make is that the holster has to be adjusted such that you don't get a torquing effect when you draw the gun. By that I mean the holster will twist outwards while you a drawing the gun, making the draw harder.

    I think this is due to the drop feature.

    Other holsters that work with the large frame Tanfoglios are the Safarliand 010, which I like (and are available from Brian Enos).

    Might want to wait for Henning to bring out his rear sight....oops, noticed I already said that

    Mick

    Thanks Eddie, you've provided me more info than I've been able to get from EAA or Tanfoglio. I have a Browning and a 1911 with Millet rear sights and I really like them. I may try one on my Witness if I can't find something better.

    Yep. I have seen a couple of Tanfoglio's go full auto during a match when the modified sear or hammer went....

    ANy reason the Tanfoglio Custom Shop couldn't use properly through hardened parts on their guns? They are custom, after all, right?

    Mick

    Henning mentioned that the stock hammer and sear were not hardened all the way through and if I were to modify them I would have to reharden them or they would wear out quickly. That is why I just went with the EGW hammer and sear to start off with. Its the same hardness all the way through.

    Next on the list of things to do is to get a custom grip built up so I can get more of my weak hands palm against the frame. I will dive into that tonight. After that the only thing left is to build up the mag release a little so I can reach it without having to shift my strong hand to do it.
