Thanks guys, I will.

I got the Sprinco Orange spring on Tuesday, put it in my short RE figuring lets see what if any difference it makes, and fired 20 rounds today. Manually pulling the charge handle to a complete stop lets the bolt come back behind the bolt catch about 1/16"+/- farther than with the original spring. Everything functioned as it should. Ejection has gone from about 1-2:00 to 3-4:00. I'll have an extra RE in a couple weeks to measure and put on to replace this short tube. Or isn't it really needed with the cycling I now have?

Odin Works who made the barrel in my 6.5 Grendel doesn't give a break in procedure. I called them to confirm and the real person I talked to told me that was correct. Just shoot it.

Rattle can paint and a sea sponge. The pistol grip is now FDE.

Cool thanks! I was hoping you would chime back in before too long.

Ok that makes sense. I will be having access to what will hopefully be a true milspec AR15 carbine buffer tube. Once I have that, what spring is recommended to work with the 2.5" buffer I already have?

Here is a great place for all things blackout. http://www.300blktalk.com/forum/ Another good one for break in/function tests is Remington UMC 120 grain. My 8" barrel SBR with can.

300 BLK is a fun cartridge. Plenty adequate for deer if you don't push it beyond its limitations. Think of a 300BLK AR as an equivalent to a semiauto 30-30. Subsonic bullets out of a suppressed SBR are just plain smile inducing when you pull the trigger and you hear what sounds like a pellet or BB gun going off. The action slamming back and forth next to your ear is louder than the bang from the bullet.

I bought the parts for the rifle individually and assembled it myself. The buffer tube, buffer, spring, and castle nut were purchased as a set designated for a 308AR and the original buffer was 2.5" and 3.8oz. I probably should have been clearer in my original post that the rifle always has and continues to load, fire and eject perfectly, as well as lock back on an empty mag. But the shells eject to 1:00. I guess I am wondering why? Is it because the spring is also shorter but heavier duty than a normal carbine 308 buffer spring? I recently added an adjustable gas block and even with the gas 3/4 turned off everything works. Its the why does it work that has my curiousity going.

My original buffer was beginning to show signs of that. The bumper section was beginning to flare over the top of the tube. The buffer tube in your picture is even shorter than mine though.

I now have seen one other buffer tube/spring combination this short and it was a thread here. From this post: FYI... PSA using 2 different buffer system lengths andbfoosh006 stated: Here are the measured weights and lengths between the "New" and "Older" versions. Again, remember these parts do not interchange... unless you the complete buffer system ( DPMS v. Armalite ) New / Armalite / Longer.......................... Older / DPMS / Shorter Supplied OEM PSA buffer ............ ( Both are way to light IMHO, they should be min. 5.4oz ) .....3.8oz / OAL 3.260"...................................3.8oz / OAL 2.5" Supplied OEM PSA Buffer Tube...... .....5.0oz / OAL 7 7/8" ..................................5.0oz / OAL 7 1/4" Supplied OEM PSA Buffer Spring..... ......1.5oz / OAL 11 3/8" / 29coils..................1.5oz / OAL 10 5/8" / 28coils His buffer, spring, and buffer tube measurements are identical to mine or within measurement method differences. When the BCG is fully pulled back with the charge handle the bolt is .1" - 1/8" behind the bolt catch. The rifle has functioned perfectly including hold back on empty magazine since its first shot. It just ejected brass about 8-10 feet out at 1:00.

It came off a Nemo arms rifle? If so how did you get it off? If it is going on a Nemo arms rifle, the rifle makes no difference as long as its a 308 barrel nut and a 308 upper with the same thread pattern. Who made the handguard it is for? My first step would be to contact them.

I've been reading with great interest all the threads detailing the need for proper length buffer tubes, springs and buffers, and the companies that manage to get them wrong. I have always thanked my lucky stars to have put together my 308AR with parts from scattered sources not knowing what I was getting and having the rifle work perfectly from day one without any of the issues I have read about. Today I measured the inside length of the buffer tube that is on it and its only 6 7/8" inside length! 7 1/4" outside length! WTF? Was supposed to be a milspec carbine tube. The spring is 10 3/4" long with 26-27 coils. .078 wire diameter. It ran fine with the original 3.8oz, 2.5" buffer but ejected out to about 1:00. I recently put in a 5.4oz KAK 308 buffer to try to tame the ejection a bit and it worked to a degree. My questions are: Has anyone heard of a tube this short? Would getting a proper length tube give me any benefits? Should I just leave well enough alone and be grateful that it eats whatever I put through it?

With our Lab puppy we litter trained him. We had a large tray from a big dog kennel (2X3 ft) and a tile floored bathroom. We used some litter to absorb an "accident" to pre-scent the litter in the tray and kept it along with his bed in that bathroom at night or when we were away from home. A dog will generally not want to soil its bed and having the scented litter tray close by got the idea across to him that he should go there. It was kinda funny watching a puppy use a litter box but it worked. Right up until he was about 4 months old and big enough to have the bombsight over the litter but the bomb bay door over the floor. By then it was an easy matter to get him going to the door.

I have 3 of their 15" slim handguards that I got for a great deal. Couldn't pass up the price. They are sturdy and installed easily.

I'll second the Awwww. How does she like the sick white crap that is on the ground in the pictures? I'm glad to see we aren't the only place in WI with that stuff still around. 12-16" of it on level ground in the woods.

Grendels short and long!!! We shoot them all!!

Welcome from WI. Have you found http://www.65grendel.com/forum/ 98Z and I are both over there too.

End around? They aren't getting around any law. They have designed a magazine for AR15s that works WITHIN the current laws of Californistan. American ingenuity at its best.

My wife watched the clip with me. Her first comment was "thats scary".

FMJ ammo no matter who makes it IS NOT legal to use for hunting game animals in most states. For game animals it must expand. Here in WI you can use FMJ for Coyotes. They aren't considered game animals

Dateline: 4/1/18 "Northwoods Ordinance Works has announced the introduction of the largest subsonic AR15 round to date. The .50 caliber bullet is to be called the 50 Ma-Beo in honor of its major components. A 750 grain, .50 caliber subsonic expanding bullet derived from what is currently used in the .50 caliber Browning machine gun, commonly called the Ma Deuce, seated in a 50 Beowulf case. The huge round will have a muzzle velocity of approximately 1020 fps and an expansion threshold down to 700 fps. It eclipses all previous subsonic loadings for the AR15 platform in size, weight, and performance downrange." Company spokesmen have revealed that the new round will function in any AR15 with three simple modifications. First: The barrel must be changed to accomodate the larger round. Second: A 50 Beowulf bolt must be used. Third: A special non-magazine must be used due to the rounds length. Each round must be single loaded and fired. They will not fit in any standard AR15 magazine. Some may see this as a detrimental factor in the new round gaining popularity but for those who want the biggest thumping bullet possible it is now available. Preorders are now being accepted for this new devestating combination.

The teacher in a Catholic grade school was just beginning her second grade religion class. She asked the students what part of the body they thought went to heaven first when we died? Little Bobby raised his hand and shouted "I know, I know". "OK Bobby tell us", the teacher said. "Your hand goes to heaven first, because when you raise it, it is closest to heaven!" The teacher looked at Bobby, smiled and said, "Thats pretty good thinking Bobby, does anyone else have a guess?" Little Suzie raised her hand, thought a minute and said, "I think your head goes to heaven first because when you walk down the street your head is closest heaven." The teacher praised Suzie for coming up with another good guess. Then little Johnnie raised his hand as high as he could and waved it as he yelled "me! me! me!" The teacher looked over at Johnnie, scowled at his boisterous antics and finally relented and called on him. "I think your feet go to heaven first!" "Why your feet?" The teacher asked Johnnie with a confused look on her face. Johnnie puffed out his little chest, and with an all knowing look on his face faced the teacher and said: "This past Saturday morning when I got up to watch cartoons there were noises coming from Mommy and Daddies room. I peeked inside and Mommy was laying in bed on her back and Daddy was trying to hold her down." ""All I could do was watch, and then she started screaming, "OH GOD YES, I'M COMING, I'M COMING!"

If you got the beer, I've got the apples. I'll even donate them to a good cause.

Never have I seen a group of people take a two word opening post and derail a thread so fast! It wasn't even hijacked! It was completely derailed down into the ditch and off into the bushes!
