    AR-15 Index Mark?

    Most AR's have this mark on the upper receiver above the mag well on the cam protrusion. It does not appear to be a casting/forging mark, but rather some sort of index mark. What is its purpose:confused:

    :scrutiny: Does anyone have data on this 45ACP bullet after its conversion to a hollowpoint as far as stopping power & expansion when powered by a 5 grain Bullseye charge thru a 5" barrel. What would be the preferred method to self manufacture the hollowpoint cavity? What would be the...

    Hey Tuner, xray of 1911 firing

    :D Yo, guys! I've really have never had a headache in my life except when I was downed backwards on basketball court about 1960. But this subject really makes my head hurt... especially the x-rays;)

    "Improving" the 1911

    Hi Xavier,:confused: There is no way a feed could have occurred since the hammer could not even get to "half cock" position after firing!:D

    I found an interesting (new?) way to press check.

    :D I guess I'll have to call it the "octopus check", ha! I really don't like to have a gun in an "out of control" position when it may be needed... but as long as there's no immediate requirement... what difference does it make, eh!;)

    "Improving" the 1911

    I like the thumb safety "as is"!;) Interestingly enough, I'd done an experiment early this year using "powder puff" loads with as little as .5gr of Bullseye behind an H&G68 200gr SWC. With that configuration, rearward slide movement is not sufficient to allow hammer to get to "half cock"...

    Recommendation for Hard Chrome Plater?

    I second Virgil Tripp. IMHO he's undeniably one of the best as proven on my Colt 1911 frame manufactured 1918! Great mag kits also!:D

    American gun owner fined $5000 in Canada

    OK... sorry about the CCW question, Dean. You're correct... it only makes sense to someone who knows what the law entails. It was asked, in hopes that someone would know from experience, i.e. an actual event.:banghead:

    American gun owner fined $5000 in Canada

    How come I can't get an answer to a rather simple question? [PHP] What do CCW holders do at a border crossings... even if they are not carrying/storing/transporting firearms?[/PHP] Alas... I must conclude that there are very few who may have experienced this anomaly & probably none of them...

    American gun owner fined $5000 in Canada

    :eek: What do CCW holders do at a border crossings... even if they are not carrying/storing/transporting firearms? Based on the event here, it seems as if it would be absolutely insane to display the fact... or do border crossing guards not count as law officers?:confused:

    Kimber ultra carry got a scratched feed ramp

    Hi Dumper,:eek: Never "polish" an aluminum feed ramp unless you want to remove its protective finish, i.e. its anodizing! Have a look on this forum re "damaged feed ramp". I think you'll enrich your knowledge a bit... but maybe more than you want!:D

    Barrel Flanging

    Sorry Tuner,:scrutiny: Barrel came with gun, S/N 434xxx which I got about 1960 for $18! Not a bad price considering what they cost now & how much has gone into it since. Didn't mean to imply that's how many rounds it had when I got it, but my count has got to be >40,000 'til sometime...

    Barrel Flanging

    Hi Tuner,:uhoh: Here's the pic you didn't want to see!:eek: In answer to your question, "Is the barrel original or is it a swap"? It's an original with probably >50,000 rounds thru it. The gun has had a very hard life & that's why frame went to Tripp Research recently for...

    Barrel Flanging

    Hi Tuner,:D Many thanx for the Nfo. My answers after having a look are as follows... but what do I know? 1. insufficient vertical engagement. Maybe! 2. slap-seating due to excessive fore and aft play between barrel and slide. Yes! 3. incorrect barrel linkdown. Don’t think so...
