    Ultimate Full Auto CMMG RDB Fixed Ejector Project

    As some of you may know I like delayed blowback setups and have been running the CMMG RDB Guard / Banshee setups since they first came out. My friends and I have been plagued with ejector spring failures. I went to a custom fixed ejector but am leary on the longevity since the slot required...

    My new UZI brass catcher

    The library references the late 'Herr-Pear's' brass catcher here: https://uzitalk.com/reference/pages/tools.htm The one in the library was his first iteration he did. Pictured below is one he did for a few of us that didn't interfere with optics. As you can see it can rotate and you can lose...

    UZI barrel nut to hub thread

    Relevant thread: https://www.ar15.com/forums/Armory/Suppressed-Uzi-Suggestions-/22-546032/ Anyone know of a 'hub' mount (1.375x24) to UZI barrel nut? I think that would be awesome to leverage all the 1.375x24 suppressors for the UZI and use a cut down UZI barrel for the most compact setup. Does...

    M16 'Ultimax'

    Some stuff I've been working on that may interest you guys: Please see link below. https://c3junkie.com/?page_id=1403 Basically, I have a few configurations working where the carrier doesn't bottom out resulting in a very smooth experience and very little gas to the face even full auto...

    Interesting FA Micro setup on Gunbroker

    I just listed a factory new IMI Mini closed bolt assembly and full size .45 open bolt assembly on Gunbroker then went to look at comparing prices and saw this listing: https://www.gunbroker.com/item/939264584 That is a semi bolt but it was modified as per the 1984 Firepower semi to full auto...

    Ultrasonic cleaning w/ CLR

    I asked Curtis Tactical what they recommended for cleaning and Joe told me they use CLR (Calcium Lime Rust) in a heated ultrasonic tank. I just did 3 cans today and I am impressed. It would fizz like alka seltzer and eat away at it. I have an MK9K where the outer tube had so much build up...

    .45 ACP IMI UZI Bolt

    Thought some of you guys would get a kick out of this. Back around 2003 or so picked up this brand new IMI .45 ACP UZI bolt for $25 and left the sticker on it. .45 bolts were cheap back then. I think it was the next Knob Creek where Blue Grass Armory was selling a bunch of them for $50...

    My new custom hybrid "MK-9K-K"

    As many of you know, I've always been a huge of the Gemtech MK9k. I like the short fat look of it on SMG's. Most of the current 9mm offerings look odd to me on a SMG. I have a couple of them and while they are very quiet, I've wanted something that is truly 100% user serviceable and...

    2013 Shot Show IWI UZI Pro and UZI Pistols

    I think this was already discussed but thought some people would like to see some pics. I wasn't expecting to see the full auto UZI Pro there. I confirmed that the lower would work on my RR Micro but they told me they would 'never' sell the lower seperately. I checked out the new UZI...

    RDIH - Closed bolt setup?

    Anybody know anything about these? Friend of mine picked up a flyer at the Shot Show. They are out of Belgium. Friend tried talking to them and couldn't understand what they were saying. I did some more reading and it sounds like they do conversions of various MG's to semi auto so I'm not...

    Another LM7 Video - 500 round belt

    I was feeding the LM7 while a co-worker was filming his 14 yr old son shooting. I told his son to use his peripheral vision to slow down if he saw me untangling the belt. I haven't made a belt box to hold a 500 round belt. Lakeside makes boxes that hold 200. Using a box, you don't need anyone to...

    230 Gr JRN .45 ACP suppressed load recommendation?

    Been a long time since I've reloaded any .45 ACP and it has always been for non-suppressed applications. Used a lot of w231 in the past but it is abrasive on baffles. I want the smallest powder charge I can get away with for use in: UZI SMG 1911's HK USP Tactical, HK45 I see that Hodgdon...

    Primer detonation while reloading

    I've been reloading for about 20 years and have never had this happen to me until recently. Over the years I've crushed many primers and never had one go off on me. Now within the past 6 months I've had 3 primers go off on me when I was trying to seat them. The first time it happened, the...

    Anybody know anything about this old ammo

    Got this from a friend. He told me that it was made for use in Sten SMG's during WWII. Anybody confirm or know what its worth? Cases are stamped W.R.A. and 9mm Pretty good condition considering it's almost 66 years old. Thanks!
