That group was the best one I've shot with it so far. Shocked the hell out of me considering it had less than 50 rounds through it at the time and it was factory ammo. Next up is to see how it likes the Nosler CC 123 grainers I have made up for my 18" Grendel. Special loads for it are soon to follow.

LOL. I was wondering when or if you were going to chime in here. Speaking of Grendelitis. Here is my new 12.7" Grendel upper painted to match and mounted on my SBR lower. What it has already done with Hornady American Gunner 123 grain.

Just don't go sticking that mag full of 300 BLK into your .223, or 1 round by mistake for that matter. Big kaboom will commence.

I've got 222 pieces of Hornady 308 Win Match brass for sale. These are all once fired and completely processed, ready to reload. They have been wet tumbled, resized, chamfered, deburred, primer pockets cleaned and squared. I had intended on keeping them for my private stash but with LC, RP, and PPU brass numbering in the gallons I'll never get a load developed for these. $100.00 for the lot includes USPS priority flat rate shipping via paypal friend/family or USPS money order.

And we appreciate all the "recoil system jackass bastard" guru advice that you dish out. No bashing of the parts used, just "do this to get it fixed". This is the best "troubleshoot my system" forum I'm on. No matter what the system. The one part I tossed from my Aero 308 parts kit was the bolt catch. The Phase 5 fits Aero reciever sets perfectly and works great. If you like the BAD lever concept.

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".
