98Z5V Posted Sunday at 02:21 AM Report Share Posted Sunday at 02:21 AM (edited) So, this has been a hole in my Large Frame AR Game for a long time. Before you start wild-catting crazy new shiit, there are 6 basic cartridges made from .308 Win. 1. Obviously, .308 Win Largest to smallest caliber: 2. .358 Winchester. Checked that box, and it's recoil heavy. I need to work on that one, and it's already got the heaviest buffer that Slash makes. It's a monster. Gonna need an adjustable gas block for that psycho fukker. It's nuts. Running 250gr projos, and just might back those down. It's insane. 3. .338 Federal. The Pig Puncher. 16". This thing is a dream, and it shoots softer than the 16" .308 gun that's it's sister-gun, and it's running 225gr Hornady SSTs. It's wonderful. (Skip .308 Win, the Parent Cartridge - I have a PILE of these things) 4. 7mm-08. Man, this thing is still a work in progress, and I need to figure out a load. It's an 18" barrel, and it's gonna be the long-distance winner from all the .308-based guns. Needs load development. 5. .260 Remington. Man, do I have an update for the 260!... It's the current slayer. Little more case capacity over 6.5C, little more speed than a 6.5C - it's just superior to the 6.5C, in every aspect. Big news coming for the 260... The most accurate Large Frame gas gun that I own... Hands down. It's just stupid accurate. 6. Final cartridge, based on the original .308 Win. The .243 Winchester. The .308 Win necked down to 6mm... I've had a .243 bolt gun for awhile, and it's sweet. A Rem 783 26" heavy barrel, Varmint model with a beautiful wood stock, and it's damn nice. Got it before Remington went under. But, I've been missing a .243 Win for a gas gun. If I'd just build a gas gun, I'd complete the family of cartridges that were originally spawned from the venerable .308 Winchester cartridge... It's not done yet, but here's the backbone of it. I still need a BCG, charging handle, scope, and scope mount. Otherwise, it's almost ready. Build list in next post.

98Z5V Posted Sunday at 02:46 AM Author Report Share Posted Sunday at 02:46 AM (edited) So, Aero Precision makes the STAG-10 Large Frame hard parts. If you're not on Aero's email list, then you never knew that. When Aero had too many left over Stag parts, they launched a "Contract Overrun" email, and were blowing these things out. It went down beginning of this year, Jan. I jumped on the STAG-10 matched receiver set for $199. You could grab the 13.5" rail for $124. Under $330, and you get a matched upper and lower, Large Frame, WITH a rail. Yes, please... When I ordered it, picked RAL-8000 cerakote (the HK416 color), and it took a month for it to come in - and I was blown away with the quality, when it arrived - and the departures from M5 - that Aero was doing. AS SOON AS... this receiver set came in, I jumped right back in on the website, and ordered another set, in Tungsten cerakote. More on that later... So, when you ordered the receiver set for $199, you could add the MagPul MOE rifle stock for $9.99. Not a typo. The STAG-10 stuff has proprietary pivot and takedown pins, and they are INCLUDED. The upper already had the forward assist and ejection port door installed. When you add it up, you got the upper, lower, rail, and a MOE rifle stock, with upper parts and pins, for $360 - SHIPPED!!!... WAY UNDER half price. I'd been eyeballing this gas gun project for several years. Wilson Combat is my go-to for weird caliber barrels. Both my .260 barrels, the .358 Win barrel, the .338 Fed barrel, the 7mm-08 barrel - all Wilson Combat match barrels. Wilson was my go-to for this kind of stuff, but they only did a 16" .243 Win barrel with their own proprietary gas system length. Eh, I wanted more, but if it's not available, I'll go there. If I have to. So, the receiver set and rail was ordered, done. Couldn't pass it up, no fukking way. I get an email from Ballistic Advantage that they're doing .243 win barrels, 18", and I ordered it THAT DAY. Bonus, what I wanted anyway. Hanson profile, comes with a pinned gas block, brand new offering, and about half price because it's new from them. We're just falling all OVER deals here... Struggled to find a VG6 6.5 Gamma brake for this, but found one on another half-price deal, for the older model. VG6 brakes are OOS everywhere, for just about everything... It's got @JBMatt's Ballistic Engineering AR Accurized trigger, and a Battle Arms BAD-ASS PRO safety. It still needs that BCG, charging handle, mount and optic - but it's gonna be a badass 6mm .308 Win gun. Needs it's own bipod, too, and that'll come. Updates in the future, as this thing gets closer - it's so close right now, it's not even funny...

98Z5V Posted Sunday at 02:55 AM Author Report Share Posted Sunday at 02:55 AM (edited) This caliber has been a box that I needed to check, in Large Frame Gas Guns, for a very, very long time... Edited Sunday at 02:56 AM by 98Z5V Quote Link to comment Share on other sites More sharing options...
