I just put together a rifle for a buddy of mine. Just waiting on some flip up sights to arrive (Brownells is on backorder for MBUS Gen2) He bought the stripped lower at SacramentoBlackRifle.com for $65.00 during a huge store sale. I've never heard of the company before, but the quality seemed par for a forged off-brand. The rest of the rifle is a basic 16" carbine, mostly DPMS parts and Magpul furniture. It's lightweight and basic. Don't need much more than this when it comes to flattening lead at the range. <thumbsup>

The Magpul MOE+ (plus) I've installed the Magpul MIAD, the Tango Down BG-16, the Ergo SUREGRIP and the Troy Battle Axe on several of my builds... I will be ONLY using the Magpul MOE+ from now on. Amazing feel and comfort. Why did Magpul wait so long to release this?

Here's the ammo; Here's the damage to the Ruger 10/22; The extractor blew completely out of the bolt and into my uncles hand. (Pic 3 and 4) Here is what's left of the mag from the 10/22; It was actually split more. I pushed the pieces back together to make it look the way it is there. Here is the damage to the Ruger 77/22; This is all I could find from this magazine; I think there was a small explosion inside the magazine as well.

Thanks all. Your support is much appreciated. For the record, my father and I each own both the 10/22 and the 77/22. Both KaBoom's were his rifles. Needless to say none of us are very happy with Winchester right now. Appearantly there was a recall on this Winchester ammo in 2007. The case was near full, but I honestly don't know when it was bought. I read that Winchester had a double load batch make it out to the masses. This would explain the KaBoom. The pictures are coming tomorrow.

I joined an impromptu shoot this weekend. My uncle flew in from out of state, then he and my father swung by and picked up the wife and me. We drove 5-6 hours to a large ranch to shoot the holy hell out of the ground squeaks (squirrels). Sunday and Monday were great days. The body count was well over a hundred. This morning all went to hell. My Uncle cracked open a new box of ammo, loaded up his Ruger 10/22 .22lr, and went to work. On his second or third shot there is a load explosion, a lot of cussing and quite a but of smoke. An explosion inside the magazine blew the mag out, cracked the stock and blew the bolt face to shit. After counting all his fingers and whiskers, we collected all the parts. We had no idea what happened. It'll be a cold day in hell before one kaboom will totally ruin the day. He quickly loaded up another rifle. This time a Ruger 77/22, .22lr bolt action. He got back to his spot chambered a round.... BOOM! This time the explosion was much louder. It appeared that several rounds went kaboom in the mag. Everything was blown to shit, more than the first rifle. This was shooting Winchester Super X Hollow Point .22lr My uncle is ok, but both rifles are smoked! Pictures coming as soon as I get back home. Winchester and Ruger will be getting phone calls this week.

That's it! I'm going to invent a picatinny mounted beanbag!! Nobody steal my idea.

You realize that because I live in California, I have to hate you for having an NFA dealer!

:rant2: >:( I'm still waiting!

Yes, but only if your change the barrel extension to a DPMS style. The DPMS bolt and Armalite bolt are different and NOT compatible.

That white sticker would look great on my snowboard!

There are two types of propellent; gas and piston. Gas can be CO2, propane or compressed air. Piston systems come in a manual (single shot) or electric (multi-shot). CO2 is pretty self explanatory. You pop in a a CO2 cartridge and you get a number of shot out of it. The propane is usually a mix of propane and oil. The percentage of propane increases the pressure. Some are known to run pure propane from a BBQ bottle. The compressed air (like a SCUBA tank) requires a large volume tank with a regulator. It is the most reliable, but also requires a shit ton of parts, and is very heavy. Almost no one chooses this option. Manual single fire guns, also called "springers", are usually the cheapest entry into airsoft. There are a few variations that are more expensive. A spring works a piston system that projects the BB. Much like a pump BB gun. The electric guns are the most common. You install a Lithium battery (LiPo, LiMn, LiFe, LiIon) and a gear and piston system allow you to shoot full auto. All of the guns are upgradeable from gears, pistons, cylinders, springs, barrels, motors, and batteries and on and on and on. A gas magazine usually holds 15-40 rounds. A springer is about the same. Electric gun magazines hold from 30 to 5,000 rounds... You can see why so popular. Ammo is a 6mm BB. They make up to 8mm, but only for very specific guns, which are usually not very popular. The 6mm BB comes in varying weight from .12 grams to as heavy as .5+ grams. The different weights are based on the composite of the BB. Almost all quality guns are measures by shooting the .20g BB. The heavier BB's are used for shooting longer distance, but their velocity drops considerably. Gas guns are a little louder than the others. They are no more louder than a standard BB gun. There are ways to suppress the sound even more. I have a carbon fiber silencer, with a foam insert, that really takes the sharp crack out of the BB coming out of the barrel. A quality airsoft gun is equal to any other quality arisoft gun. M4 vs AK vs HK... It's doesn't matter because they can all be the same rifle on the inside. The appearance is strictly cosmetic. Take the body off and they are near the same, and they all shoot the same exact ammo. A starting electric rifle will begin at about $200. Then buy a battery and charger for another $75. BB's are about $15 for 5,000 rounds. That's just a basic idea of what airsoft is. There is a LOT of info out there. Airsoft is a smoothbore shooting system. Most guns now provide a "hop-up" system. The Hop-up is a rubber nub located at the 12 o'clock inside the barrel, that provides a backspin on the BB. This helps accuracy and increases distance. Just to give an idea on my favorite airsoft rifle. I spent $350 on the rifle, then dropped about $600 on additional "cosmetic" parts. I upgraded the motor to spin at a higher RPM, which gave me a faster rate of fire. I bought several batteries and upgraded the electrical system inside the gun to hasten the trigger response of the rifle. The red dot on my rifle wasn't added to the total cost, because it is a real Aimpoint CompM2. My rifle shoots 25 bb's per second at 400 fps, with a maximum distance of about 200'. It's damned accurate to boot. I have seen guns that shoot over 40 BB's per second. I have also seen guns that shoot well over 700 feet per second. Airsoft guns can injure and be very dangerous in the wrong hands.

I've never seen a barrel that short with a 1:9" twist. Are you planning on shooting the lighter loads (ie; 55gr)?

I'm still waiting on my MGI Enhanced Bolt to arrive, and my MBUS are still on back order from Brownells. Pictures will be up soon.

Bingo BANGo! <thumbsup> The method to adjusting a gasblock is to open it up completelty, then adjust the restriction till your rifle stops cycling. Once you find that breaking point, adjust it back 1/4 turn for reliability. That's not my idea of reliability, especially since anything "adjustable" has the ability to come maladjusted.

The problem is that both the .308 and the 7.62x51 create a LOT of gas. The AR's are still using a gas system that was designed for the 5.56x45 and .223. Even the AR-15 is getting away from carbine gas, unless barrel length forces it. In reality, you should have a rifle length gas system on your 18" barrel, or at the very least a mid-length. A .308 requires 15.5" of barrel to make a complete burn. If you have a gas port at 7"-9", you are pushing a lot of burning powder through the gas tube. It doesn't matter how much you restrict the gas flow with an adj GB. The burning powder still creates expanding gasses inside the gas tube. The more expensive, yet appropriate, correction to your rifle would be to contact Fulton Armory and look into one of their 18.5" rifle length barrels... Or even better yet THIS ONE. The FA barrel would allow for more of the powder to burn in the barrel, rather the gas tube. This would be a better regulation gas than the adjustable gasblock. Unfortunately this a $300 fix vs a $50-$100 remedy. As for the BCG traveling "TOO FAR", that's only possible if you had the wrong buffer and buffer spring installed. Even then, you should notice that a full compression of the buffer spring is occurring when the buffer slams back hitting solid resistance... As long as you have .308 specific parts installed, I don't think this is happening. I think the bolt is traveling so fast, that it is already returning to battery before the casing has left the receiver.

Seeing that you have an 18" barrel with a carbine gas system almost says you are over gassed by itself. It amazes me that manufacturers are still using carbine systems at all. The adj gasblock is one of multiple options you can choose. What you main objective is, is to slow your cyclic rate. This can be done by limiting the amount of gas through the action, adding weight to the carrier, or improving the buffer system. Your first answer (from the gun shop) was good sound advice. 308 AR's like to be sloppy wet when they break in. You next step should be measured carefully. The adj GB's can work, but if this rifle is one that your life is going to depend on, I never suggest this option. The trick of tuning the GB is that you are going to be shooting one type of ammo and you expect little to no variation in bullet performance. Seeing that you like Mil Surp ammo, I think the adj GB should be your last option. A Tubb Carrier Weight System or a HEAVY BUFFER with a power spring would be an easier, and more likely beneficial, remedy.

PM sent re: CTR and buffer tube

It's an easy answer, but it ain't cheap. 1. Only option I know of is a 1911 2. Get it chambered in 10mm, .400 Corbon, 45 Super, or .460 Rowland (although I think .45 ACP is plenty) 3. Find a suitable conversion kit. Total, about $2k-$3k out of pocket

Yesterday I saw a Ford F350 covered in black bed-liner (FBI owns it. They brought it out to a training session we hosted. So sweet!)... I'm pushing for the bed-liner coating again! It's durable. It's scratch resistant. It's redneck!

There are no 308 specific gas tubes for the LR308. Feel secure buying the AR15 version. The only specific tube is the Armalite AR10 rifle length, which is slightly longer than the LR308.

The only plasti-gun I'm remotely interested in is the ACR. The FNH rifles seem like a lot of hype over performance.
