    Re: my Colt AR 9mm

    For some damn reason, folks will not let go of the Colt 20s (9mm)...

    With the normal ARs, every damn body and their brother wants 30s and get moist if they see a 40....

    But in the 9mm mags, hell to the naw, they ain't selling the 20s.... rat bastids... They don't want the 30s...

    I have never figured out why the AR 9mm mag craze is opposite the the AR 5.56 mag craze....

    Marines still shoot 500 yards in boot, where all other branches shoot 300 meters.
    The Corps is weird like that. They shoot in yards, but everything else is meters and klicks.
    And as for those pencil barrels, their main malfunction was rapid over heating. They were skinny 20" barrels, and when you really got it on, especially with surpressive fire power, them babies get hot!

    I can dig it!! What a great idea!

    I have an adapter for my M500 too..just need the poker..it's either gonna be the OKC3S, or M9:

    Smith and Wesson offer a M9 type as well..which looks to be a cross between a M9 and the USMC OKC3s:

    Saves me the work of silver soldering on a lug on my barrel. I'm gonna get one for my rifle. Now all i need is a stack of hay bales, a reefer, to really have some great bayonet time. I've got a life size Jane Fonda poster to tack onto to it with at least 30ft. to really get moving, and get my rebel yell on.
    When i showed it to my partner he laughed, went and got his army figure with fixed batonet. Too much fun!

    I really don't know much about the bayonet and its usage after my time. Do they still issue them to troops that can be used on their rifles and shotguns ??

    Luckly, i never heard the command, "fix bayonets" execpt in boot camp, where we charged, and stabed a Damn tire or something. I dont remember now.

    Looks like he's ready to do some shootin'!

    When I was a lil guy,..I had a full on camo outfit, ALICE gear and even a green beret!

    I would go DEEP in the woods..I pretended to be Special Forces..and took it VERY seriously.

    We didn't that day. Target stand building. But right out side that door in back i have a firing range on my property.
    Soon I'm going to add a firing recovery tank in the shop where i can fire down into a water tank under the floor to recover bullets.

    I'm sitting on a bunch of M193 type stuff..M855 is good to go with 1:9, correct? (just not indoor ranges)
    I may snag some if so, but I don't get to shoot outdoors much.

    You better believe it. A 1:9 twist will handle 55gr. Thru 62gr. Just fine. If you go above 62gr. in my experience, you should be looking at a 1:8 or, more standardized 1:7 twist to get really good performance. Once you get up there in bullet weights like 77-80gr. you will need 1:7 to stabilize projectiles.

    Note: concerning self defense, even if they do tumble, as long as its in a straight line, the effects on the human body are devastating. Isn't that the desired end result outside of paper ?
    *Mod Edit*

    Two things:

    1) A little heavy for this thread, Froggy. Remember the premise of this thread; all things of sports shooting. No actual military combat actions, please.

    2) If you post photos and ask them not to be re-posted, that's sure-fire way for people to save them and post them. Ask me how I know.

    Private stuff should be kept just that: Private.


    If I'm not mistaken, you don't reload. If you did, you could take advantage of many different bullets and loadings. I load the heck out of both of these both -

    IMG_20171203_102933_7791.jpg
    Left to right, 60gr. Sierra 60 hollow points, and Hornaday 60 soft points. Why ?
    Varmit bullets are manufactured to very high standards. They are specifically designed for long range accuracy on Marmots and other critters, usually with high BCs, which produce extreme long range performance and reliability.

    The idea (for me) that one has to digest just milutary ammo only is just limiting my performance capabilities.

    The main reaaon i dont divulge into other calibers requiring reforming brass is, I've been down that road decades ago with Steve Herrett. I loaded both the 30 Herrett, and the .357 Herrett for ever. I still have the dies, loaded rounds and a barrel for each one. Thete have been others too. I just don't want to mess with redorming brass anymore, but allot of folks do, and that is great.

    I have had a pretty damn good day!!

    I went and shot!

    First, the Kimber came back from the factory Wednesday so I wanted to go run some rounds to see if it was all good....if you saw my earlier post, you know I traded for this gun a few weeks ago and it began having FTF issues, I identified that it was the slide stop but had no idea that it was an aftermarket part....since the weapon was only 10 months old, I sent it back to let them deal with it....

    Kimber Replaced the aftermarket slide-stop with a factory Kimber slide-stop, (the guy I traded with for the S&W is picking up the $35 tab...said he fired exactly 7 rounds through it and it never happened....that was about right, I would fire sometimes a full mag before FTF, but not often)..
    they replaced the recoil spring & ejector, reamed and polished the barrel chamber....all for free! Thank you!!

    I fired 98 rounds and it did not so much as flinch....I was struggelling a little with where the sights were hitting in my picture compared to my Sig and there were no adjustments.....I have been looking at night sights anyways, but had stalled that to see what happened once it was back fro the factory.

    Now comes another twist, last night I saw an ad on Armslist for an AR15...I had been sort of thinking about once since I ran up on and bought a sight-mark red-dot a few months ago...didn’t need it but the price was right, so I put it in the safe.

    Anyways, the listing for the AR read correct in most all ways, especially the price, so I responded.

    Got got in-touch (he is a disabled Vet) and agreed to meet near my studio which is about 75 min. From me and 30 from him....

    The AR was all he said and more, to be honest, and had a LOT of extra parts so, hell I bought it.

    My first impression of the Magpul Mbus flip-up is not much but other than that, it is a SHOOTER....

    Here is the specs on it and a few pics because I know how us fellows are!

    Hell, while I am at it, the Kimber, and my EDC Sig 230 SL that I am hoping is about to become my back-up to the Kimber.

    Your rifle looks great! Personally, the first thing to go on mine was the Magpul flip sight. They work fine, but I'm not into plastic for sights, i need something more durable and versatile. That is why i replaced mine with the A2 rear sight.

    But i also like the gangster grip as well. These make target aqusition faster for me, and the weapon is more controllable. Just personal preference.

    This one was given to me by a former Ranger, and features a deployable bipod at the touch of a button. Great for longer range shooting stability.
    Good looking stuff you have troubadour..

    Picked up my clearance blem Brownell's A1 lowers today. Nice looking lower (considering that they have incorrect fire/safe markings on the right side and are the wrong color for an A1) Going to fill the right side markings and spray them a proper grey with either Duracoat or Norrell's. Will probably mill away the lower portion of the fence on at least one of them to convert it to XM16E1 profile (might as well, since they need a refinish anyway).

    They look way lighter in the pic. If they were actually that color, they would be correct. In person they are black.

    Were they a pretty good deal being blems?

    I figured while I was at it last night, I would photograph the pair of AR’s I now have....

    They were originally marked down from $150 to $120 for the incorrect markings, then down to $84 on clearance, plus I got an additional $15 off the two and free shipping. They were a good deal considering that retro profile lowers are pricey (the NODAK lowers cost even more than these, if you can find one).

    I have five NODAK XM16E1 80% lowers that I need to mill out too.
