308kiwi

This is one of my safe queens, it's my competition rifle, I used to shoot a lot of IPSC Rifle competition, not so much now, not enough time and I'm not as young and fit as I think I am. 18" 1:8 Krieger barrel, I chambered it in .223 Wylde, JP BCG and recoil system, Elftmann Trigger, (I just fitted this recently, which is why it went out to the range today, to have a play). The stock is an AIL that a mate here in NZ makes and sells locally, very similar to the ACE stocks Upper and lower, well you'll not recognise them, machined up from two 2" thick slabs of 7075-T6 tool plate, a mate and I collaborated on the design, I machined the bore in the uppers and profiled the lowers then he finished them in a very freakin cool 5 axis machining centre that he had access to. There are two sets of these, I have one and he has the other.

That wear in the upper from the BCG is unusual to say the least, I have seen it before on a very old Colt M16 that a friend owns. My guess is that the BCG is being pushed up into the roof of the tunnel by the hammer/hammer spring, were there not a gap there, the cam pin cut out, you'd probably not even notice the wear, it more obvious on the front side of the cut out because the BCG has 'tripped' over it, in the pics it clearly sows the witness wear all along the top of the BCG tunnel beside the charging handle channel. FYI the cam pin cut out is machined after the BCG bore in the machining process. Below is a pic of the last upper I machined from a block of 7075 tool plate, first step was to bore the BCG tunnel.

I hear ya, believe it or not there was a news article on the very subject of 3D printed guns and desk top cnc machines on our local news channel just a few nights ago. I've always considered the gun culture in the USA so deeply entrenched that is would live in perpetuity, never thought the lib-scourge ever had the balls let alone the power or means to have any effect, I guess it just goes to show you should never take anything for granted.

This has been followed closely over here as it has ramifications with ITAR as far as exporting firearms and parts etc. Good news all around I say

Yeah I know, sorry, I was trying to link this thread to the other thread that is in regard to buffers hitting the buffer retaining pin, but it didn't work? But my whole point on this thread was that I don't think that step you have on your rifle between the locking lugs/feed ramps and the inside face of the upper should be there, it's not helping your feeding issue and it could also cause the buffer to contact the retaining pin, I'm sure I don't need to say that the position of rear face of the locking lugs is what determines where the bolt group ends up when in battery, so if it shifted forward, lets say .040," then it'll let everything behind it shift forward .040". Is the rear of your bolt group, when locked in battery, dead flush with the rear face of your upper? Cheers.

Agreed. Both my 308 upper and my 243 upper, (one is an M5 Aero the other is an M5E Aero), I barrelled using BAT Machine barrel extensions and they both fit flush to the inside face, without MinMD66 pulling the barrel and measuring the distance from the end of the extension to the shoulder that seats against the front of the upper thread we will never know.

In both of my Aero uppers the barrel extension fits all the way to the inside face of the upper, IE they don't have the transition step that is in the pics MinMD66 posted. (sorry for the crap pic, but hopefully you get what I'm saying). This I believe is possibly the issue that some are having with buffers being chewed up on the front face, if the barrel extension is forward of the face in the receiver then the bolt group is going to be in battery that much further forward, allowing the buffer to also travel that much further forward and contact the retainer. Sorry I don't know how to link this to the other recent psot that someone made about buffer damage. That's my 2 cents worth for today?

6 deg, (forward) is the angle for the buffer retainer bore.

Yeah they definitely don't taste like 'chicken ', more like a cross between venison and beef, quite dark meat but they are damn good eating. the one in the pic is a juvenile, they stand about 4-5 ft as adults, quite a big animal, I posted a pic here of an adult buck I shot a year or two ago, he was just shy of 5 ft, they are SO MUCH FUN to hunt, freakishly fast moving animals, like leading them by a body length is pretty std, you seldom get a sitter, especially when the dogs flushing them. They are an introduced pest here and can be hunted but they are protected in their native Australia. Yeah ole Yaeger is a pretty cool dog, he LOVES flushing these things, he's getting pretty old now and was absolutely knackered in that pic.

Out after some Wallaby this weekend, winter brings them down from the snowline, makes life a bit easier to go after them. Good eating. Wife with her first Red Neck Wallaby, with the help of Yaeger the mutt and her trusty AK, proud as punch....

DPMS 308 catch for comparison, I got a couple of spares from Brownells after breaking mine, part # 231-000-273WB $9.99 each

I wouldn't be that lucky, I'd trip over my own Y fronts, smash my head into he door frame and wake up in a gimp suit in her basement..........the risk-reward is just not there.

Man that's just nuts.

Same. I was in a retail shop the other day, at the counter in front of me was this long haired brunette wearing the tightest jeans ever created by man I was very distracted by the fine shape that they made, was just waiting for a dig in the ribs from my wife who was standing next to me and I'm pretty sure she knew why I was quietly looking down in front of me, anyway, she finished being served and turned around, holy F**K, must have been 75 and looked like some witch type character from some B grade horror movie, I'm sure the wife had a laugh to herself and thought, 'well that'll teach you'

Can any of you fine gents ID the forend on the AK in the attached pic, I seriously need to build myself one of these little carbines.

Had had an interesting and challenging project on the go last week, a mate who shoots IPSC in Open Division had me build him a pistol in 9mm a few years ago, now he's decided that the comp I made was too small and decided I had nothing better to do than machine up a 3 port comp to replace the original 2 port one I made when I originally built the gun for him. f**k I love mates like this. Original gun I built for him on an STI 2011 frame and slide with a perfectly adequate 2 port comp.. Machining up a new comp from scratch out of some 316 Stainless bar...finished it today, told him he'll have to like it or lump it cause I aint building another one, getting the radius’s right to match the slide has caused me quite a few new grey hairs?

Great idea, and a whole sh*tload easier to do than drilling, reaming and pinning.

?yeah our cat is particularly smart, she's been around a long time and knows what’s best. Screw that Sisco, -32F, coldest I've ever seen the mercury here was -21C, (-6 F) and that was cold enough for me, spent that day thawing out diesel fuel lines and filters to get machinery running and stock fed.

Lazy ass cat knows the best place to be..........

? Ventured into town today, local gunshop having a mid winter sale so I felt obliged to go and spend some money, 6 deg, (42 F) at lunchtime, decided 'screw this' went home and have the fire lit now.

I do a bit of work for a local gun shop, mainly threading barrels for suppressors, they 'pay' me in shop credit which suits me just fine. Cashed in a chunk of shop credit today on this lovely piece of German glass, Minox ZX5i, 1-5. Can't wait to take it out and have a play?

I'd never heard that term before, "feels like" until we were in the states, I thought it was rather unusual, but hey. Spent a couple of days in your hometown last October DNP, loved San Diego, clean, friendly, GREAT restaurants with awesome hospitality, was certainly one of the highlights of our US holiday.

Yeah I know you guys are all basking in the balmy warm and brilliant sunshine, but it's winter here, just poked my head outside because it all of a sudden went quiet, yep, it's friggin snowing. Too dark, 9:30 pm, to take pics and make you all feel chilly, will see what tomorrow brings.

Any mag with greater than 10 round capacity requires a US State Dept export permit. You will need an import permit for the destination country in order for the US State Dept to process your export application, OR a Certified Letter, (Govt or Police issued), stating that the items don not require an import permit, you also need to fill out DSP83 and End User certificates to accompany your application to the US State Dept. You will need a US State Dept registered exporter to submit all of this for you, along with your $250 US fee for the application, (non refundable if the application is declined). Have been through the process many times exporting mags and various other parts etc out of the US, definitely viable but it's not a cheap nor fast process, processing can take months and approval IS NOT guaranteed. I used to use all sorts of different exporters for parts but have been burnt by a few less honest ones so the only exporter I will use now is Brownells. Hope this helps.... (If the capacity I quoted has changed and someone knows better, please feel free to correct me, last time I imported mags 10 rounds was the limit before an export permit was required)
