Welcome from Woodruff

I was thinking of doing exactly that. I eliminated the entire internal rib on two 30 round Pmags to run subs as long as I could in the mag. Both of them work just fine. I wonder how Magpul would feel about replacing the 6 Pmags my son bought to use with this blaster.

Ummm, what is Tom's favorite saying??? Don't complicate shiit with complicated shiit!

This is what I did and I think I found the problem. I loaded 5 rounds, fired two, leaving the third in the chamber, then verrrrry slowly dropped the magazine out of the lower and this is where I found the 2nd to last bullet. Not even IN the magazine, but sitting on top of the last bullet and the right side feed lip bridging them. This was with the 30 round Pmag, and it happened more than once. In a 5 round ASC metal mag and a 15 round C-Products metal mag, all 5 rounds fired perfectly with no sign of the 2nd to last bullet bridging out of the mag. My buddy the gun pusher (yes I have one too) loaned me a 30 round Lancer L5 300 BLK mag to try and it worked perfectly too. Apparently this thing is allergic to Pmags and prefers longer nosed bullets. Luckily I have 100 Barnes Tac-Tx bullets to load up to use for hunting and theres no need to use more than a 5 round mag in a hunting situation. Hopefully mystery solved.

The last round of shooting I did to try to figure this out was using 5 rounds in a mag. 1, 2, 3 all went bang. #4 which is 2nd to last went click and jammed. In all the mags I tried. The long nosed Barnes Tac-Tx worked when used in the 5 round ASC mag, all 5 rounds went off. The bullets that jammed in all the mags were short nosed Nosler 110 Varmageddons. Shorter nose than the Barnes with a steeper ogive angle.

That is one thing I haven't tried yet. But you can bet I will.

No kidding! My 16" pistol gas carbine with the same buffer parts in it shoots anything I put in it flawlessly. My understanding is that the 300 BLK was designed to use a carbine (3oz) buffer and regular carbine AR15 spring.

Yes. I've tried 3 different mag manufacturers, 30 rd Pmag, Colt 30 round steel, ASC 5 round steel, and most common jam is 2nd to last round. It has happened on 3rd and 4th on one or two occasions. Its weird as h*ll.

We're fine except for this foul up. Original buffer is fubar. Steel weights that act as if they were pressed in. No way they are coming out. Ran the 110 Barnes Tac-Tx through it this afternoon. They ran in the ASC 5 rounder and jammed in the 30 rd Pmag. This was with the spring and 2.8 oz buffer from my working 300 BLK pistol.

I just got back from the range. Thank God its only 10 minutes away. I put the spring and buffer from my working pistol into my Son's gun. Same malf with both 30 round Pmags and a 30 round Colt steel mag. The 5 round steel ASC mag fed fine with no feeding issues at all. Next step is to take some weight out of the 4.6 oz buffer and see if it will run with the original spring. I'm also considering the possibility that the bullet length isn't agreeing with the gun for some reason. I've got some 110 gr Barnes Tac-Tx loaded up for hunting and I'll try those next.

My Son's BLK pistol has come up with an odd feeding failure. The 2nd to last bullet in virtually any magazine used will hang in the feed ramps with its nose buried into the top of the chamber entrance and the bolt wedged into the top of the case. After the jam. Pull the bolt back, drop the mag, jammed bullet drops out, reload bullet into mag, slap the mag back into the gun, release the bolt, and it fires the previously jammed bullet and the last one in the magazine as it should. It has done it once on the 3rd to last bullet, and it has done it using 30 round Pmags, 30 round colt mags, and 5 round ASC mags. You can run a 30 round mag as fast as you can pull the trigger and it fires perfectly until you get to that 2nd to last bullet. I have rounded the edges of the ejector before trying the 3 different mags and the malf continued. I just finished weighing and measuring the buffer system parts of this BLK and my 8" pistol that works perfectly. Tossing in weights of buffers of two other working guns. The 16" BLK that works has the same buffer system as the 10.5" malfing gun. 10.5" malfing gun 8" working gun 16" BLK working 16" Colt Carbine 4.6 oz buffer weight 2.8 oz 4.6 oz 3.75 oz 10" spring length 10.5" 34 # of coils 37 .071" wire dia. .074" My first thought after taking weights and measurements is this thing has too much buffer weight for the spring that is trying to push it. I plan on doing a spring/buffer swap using the 2.8 oz buffer and 10.5" spring out of my 8" pistol and see what happens. Bullets used were 110 gr Nosler Varmageddons loaded over 19.0 gr of Lil'gun to 2.060", in a WCC cut and formed case and CCI 400 primer. They have been universally accurate and functional in 4 different 300BLK rifles so far. Am I on the right track? Any advice would be appreciated.

Can we call this welcome thread officially hi-jacked? Welcome to the loony toon room from WI

@dpete looks around and tries to see the rat bastards currently being flipped off. "Nope, don't see any!"

He ain't rough around the edges! His edges just seem that way cuz he is smooth on the inside!

PM sent @RedRiverII

I kinda figured they would find a home amongst the sand and cacti. If you're cool with waiting until the end of Nov. after deer season I'm sure the 300Win Mag and some others will continue to roll in. We'll get you a good box full.

Do you want me to add the new 6.5 Creedmoors to help fill out the box/envelope? I'm thinking they will all fit in a padded envelope. I'll ship in whatever is cheapest.

You are correct. They are cut down 5.56/223 brass that is now blackout. Its a random mix of several headstamps including LC, RP, PSD, FC, PMC, and other usual 223 brands. I would guess its mostly LC.

The barrel is probably one contour heavier than a pencil barrel. Ok I was wrong, Fulton Armory calls it a lightweight barrel. https://www.fulton-armory.com/barrelfatitan185lwcm1x10750gasblockchrome-lined.aspx The scope mounts are made by Nikon. Yes you can move them around or flip them around to accomodate many different optics. https://www.natchezss.com/nikon-p-series-2-piece-ar-scope-integral-rings-base-scope-mount-reversible-1-matte.html I have both the 1" and 30mm versions.

Here are some real world stats for you on "Bertha" (wife named all my rifles). Aero M5E upper, 15" handguard, lower. Criterion 18" midweight barrel. As pictured without magazine she comes in at 10 lbs 2 oz Not too bad to carry but I do all my hunting out of tree stands so the carry is never bad

The etsy pictures look similar to stuff available at Fleet Farm around here.
