I recently finished putting this guy together - my 2nd AR build and first experience with the 6.5 Grendel. I had been watching this builders set for a while and decided it was time after noticing it had a price drop and was also on sale.
Parts list:
Accuracy is just ok - nothing to write home about for sure yet. I haven't started reloading for it yet, but I will after I shoot through this factory ammo I have. Oddly, I can shoot one group of a given ammo and it could be in 1 hole at 100 yds, then load the mag with another 5 rounds of the same ammo and immediately shoot another group and it might be 1.5." I'm hoping reloads will be more consistent.
I did have a handful of issues and oddities I had to work through:
I had major problems with it short stroking at first. The Hornady 123 SST factory loads, which were the hottest ones I had, would not pick up the next round sometimes, or lock back on empty. Lighter loads, like the Hornady 100gr V-Match, sometimes would not even push the BCG back far enough to cock the hammer. My BA barrel came from the factory with a .096" gas port at rifle length. I saw other people reporting theirs were .094". I did test this upper on my other lower setup with a standard carbine tube and standard weight buffer - same short stroking. I also tried swapping the bolt into my other carrier from my 5.56 because it looked as though there may have been a leak around the front of the gas key on my AR Stoner carrier - no improvement. After working through every possible thing I could try (without spending money), I lightened the buffer weight to H0 weight, and opened up the gas port in the barrel to .100". It now locks back with all my factory ammo except the Hornady 100gr V-Match. I am hoping that I can tune reloads with bullets around that weight to lock back properly.
I had an irritating issue where some part is out of spec, causing the bolt lugs to not line up perfectly with the barrel extension lugs, smashing into one edge of the barrel extension lugs. I suspect it is either the upper receiver or the bolt carrier. Moving the bolt by hand feels ok, but if you push it certain ways, you can feel it contact the lugs. It also will contact the lugs when a magazine is installed. Myself and my dad, who is a gunsmith, decided it's not really a safety issue but rather just irritating, so I left it as-is.
The Alexander Arms/E-Lander magazines are very snug in the mag well in this lower. They will not fall out on their own - you have to wiggle it a bit to pull it out. The other mag I got is a Duramag 10rd which fits and works fine.
The slot in the lower receiver where the trigger drops down into the trigger guard was not wide enough for the trigger on my RA drop in. I had to put the lower in the milling machine and mill out another 10 or 15 thousands to get the trigger to drop in.
Overall I'm pretty pumped about it and looking forward to doing some long range shooting and finding some coydogs. Recoil is very minimal with the A5 setup - definitely less than my 5.56 with a standard carbine lower.
I’m wanting to turn my new tack driver into a hunting rifle. What are your thoughts on the range of a 12 inch 6.5? I’ll be hunting in Texas and can’t imagine taking shots over 200 yards but what would you say is the longest ethical range for a hunt?
I’ve been looking for a chart with foot pounds at different ranges but can’t seem to be able to find one for a 12 inch.
Thanks guys!
Hello, I'm looking to buy a ar pistol in 6.5 grendel for deer hunting whitail at about 300 yards and closer. It has to be a pistol to be compliant with local hunting laws. I see a lot of guns with the ~12in barrel length and I'm worried I'd be stretching thin out at 300. Does anyone have any suggestions for a 14in or similar barrel length production gun? Or is 12in good enough? I'm not really interested in building right now.
18" with 1 in 8 twist. I have struggled to find a round or load a round that will consistently produce sub 2 moa results.
I check the testing setup (sled and bags) with other rifles it doesn't appear to be to that or my shooting form as I can produce 1 moa groups with my other rifle.
What are other folks shooting out of this upper? I know you're out there as this is one of the most common ones posted.
What's working for you?
Thanks in advance.
The long range side of shooting recently caught my eye. I currently am shooting a pistol length 6.5 Grendel that fell into my lap. After some research it sounds like quite the cartridge. I was wanting to take a long range class to learn the basics and was thinking about putting together a 6.5 Grendel AR15 with a PSA 20 inch upper. What are your thoughts on its ability to shoot 1000 yards with appropriate glass. Thanks guys
I’m struggling to get my form 1 approved. It’s been a long back and forth. Sounds like maybe they changed the required process for fingerprints to be sent in recently? If I understand right, it requires an EFT file? Which from what I read, can’t be done by a consumer? Any knowledge on this?
I just want my 6.5 back in operation!
I have a Diamondback barrel and the website states that it’s a “Type 1”. If I buy a “Type 2” BCG, will it work?
Recently bought a 30 cal, 5/8x24 muzzle brake but yet it’s too small for my 6.5 barrel.
Any info on what I should look for that will make sure it’s a wider diameter?
Looking at a 6.5 Grendel, standard AR platform, but if there are drum mags for it, that'd be awesome.
I have the AAC , but looking at the hxwrx flow 6k. It says it is rated for 6mm
Does anyone have experience with these two cans on a 6.5G?

Seen some H322 on the big box shelf but this one is still as rare as
I’m looking for a decent projectile for 6.5 Grendel that is cheaper, so I don’t burn through all my SSTs.
Iv been looking into the 120gr HPBT from PPU, but aside from hunting questions, and a thread on 6.5 Grendel forum, Im not finding many reviews on accuracy. Iv had great luck with some PPU projectiles in the past, and some very average results depending on caliber.
Any of yall used these and can speak on their performance?

PSA 18" RIFLE-LENGTH 6.5 GRENDEL 1/8 STAINLESS STEEL 15" LIGHTWEIGHT HEX M-LOK UPPER - WITH BCG & CH & VORTEX GEN2 STRIKE EAGLE 1-8
Anybody have any idea when these might be in stock again? I emailed the company 9 or so days ago and didn't get a response. Didn't try to call because I hate being on the phone. Thanks in advance!
I was loading up some 129gr Interlocks last night, and went to check the C.O.L., and mine is listed as 2.140”.
I had already seated them to the bottom of the cannelure and was going to refine further from there. I checked my measurement and I had 2.270ish”.
I’m assuming 2.140” is a typo, considering all of the other listed projectiles are in the 2.240-2.250” range. I’d just like some clarification. I’m new to 6.5 Grendel and am left wondering if there is something about this projectile that I’m missing.
Edit: I purchased the data for 6.5 Grendel on Hornadys app, and apparently the data in the book is wrong by two digits. The COL listed on the app is 2.245”
I've gotten 5 boxes of the ammo shown below from PSA to start off with but wanted opinions on it and/ or other brands that work well in an (Anderson) AR platform. Or is it going to be unique to an individual gun...trial and error?
Brand: AAC Bullet Type: Full Metal Jacket Bullet Weight: 123gr Bullet Ballistic Coefficient: .266 G1 Velocity: 2525 FPS
Brand: AAC Bullet Type: Sabre Blade Black Tip Bullet Weight: 123gr Bullet Ballistic Coefficient: .510 G1 Velocity: 2525 FPS
Can I use my AR reaction rod to mount a muzzle device on my grendel? Is the barrel extension on the grendel the same?
I’m building a Grendel for deer/pig hunting. It will eventually be an SBR’ed lower but a pistol to begin with. I found the Satern 10.5” barrel, but most barrels I’ve seen are 12.5”. This will be full time suppressed, does the 10.5” really give up that much ballistically? I want as short of a package as I can get, so 2” matters a lot. (Insert the jokes here). Shots will be from 15 yards to 250 yards max. I don’t see the 10.5” suffering in this range myself.
Also any advice on spring/buffer weights for the short Grendel’s? My 5.56 shorty suppressed go to is a blue springco and an H2 buffer then tune from there.
Just bought this in a GB auction; have read mixed reviews of Anderson but the entire package (scope, mount, stock, muzzle brake, SS barrel, reloading dies and brass) made it attractive and $500 bill got it. Thoughts? Did I buy a pig in a poke? Here to read up and learn. I already have an FN-15 5.56, bolt action 30-06, 6.5 Creedmoor, 91/30 Mosin, Mossberg 88, Tokarev tx3 20 ga among others
