Other reviewers mentioned it. This reaction rod is "clocked" - with the raised "fin" it does not fit into the star chamber. My first thought was that my barrel was clocked, but I've tried it in 4 different uppers, and it's the same everywhere. I got a replacement, and it was identical. Without raising the index fin it "works", but then it has limited use, not what I needed. If you are removing/adding a muzzle device or replacing barrels, you need the "fin" to stabilize, and prevent putting stress on the upper.

Meanwhile I have the 308 version of this, and it fits just fine.

Props to Trybe, a gentleman from them reached out within a couple of days of my review, genuinely trying to figure out the issue, requesting photos, and a description of what's happening. He made sure we're talking about Grendel Type II across the board (yes, we are).

I am very impressed. This seems genuine and not just "here's a replacement" or some other freebie. While a replacement was promised, the understanding is that they'll try to address the design, to make sure the product works. I'll take that as a win (when completed). Everyone goes through issues, defects or mistakes. It's the way they handle it that matters at the end of the day.

Looking forward to see what they end up doing.

I WILL 100% POST AN UPDATE ONCE THERE'S SOMETHING TO REPORT.

I have a nice Stag Arms Pursuit 15 upper in 6.5 Grendel. It's an 18" barrel with rifle length gas system. Purchased as complete upper and paired with a complete premium Diamondback lower, their "Diamond" line. Very nice. Using AAC 123 gr ammo, brass casings, never used steel.

Being completely new to Grendel, when I started having issues, I thought it was the upper, maybe not enough gas, or way too much. Even spoke to Stag Arms, who were willing to help, but it took me a while to get back out to the range to test more, so that was on hold for a few months.

After reading up on this issue online, I started suspecting the bolt, and especially the extractor. I purchased two of these Trybe Defense complete BCG's with 6.5 Grendel bolts, and both of those were not functioning - failures to extract, ejection issues, double feeds, bent casing neck, etc. I also tried swapping in a Cryptic 6.5 Grendel extractor from Optics Planet - same issues. I've tried buffer weights from H3 all the way down to stock carbine buffer 3 oz (suspecting that maybe there's too much gas - sometimes that can look like not enough gas).

After learning that Grendel extractors need to have a certain geometry, especially to avoid having "claws" or "fangs" (sharp corners) that grab onto the rim and prevent smooth ejection, I ordered two complete bolts from Grendel Hunter. Ran 40 rounds of the same ammo flawlessly, with different magazines. The Trybe carriers themselves work just fine, it was only the bolt and ex

Trybe Defense BCG's seem to run fine in 556 and 308. But calibers like Grendel require someone with attention to detail to manufacture them.

Comparing closely this Cryptic extractor to the one I got from Grendel Hunter, it's not just the way the corners are rounded, it's also the width of the groove where the rim of the casing fits. I am well past returns on this one, so I

I got this, along with the NiB bolt, to have as backup. I have a simple Diamondback DB15, along with a full spare nitride BCG by Trybe. So I installed the Trybe NiB bolt and this cam pin into the Trybe BCG and put a few mags through it the other day. Zero issues. I can't comment on durability with a high round count, but as a spare it should be great.

So far I have tried Trybe's charging handles, complete BCG's, and now this cam pin and bolt. Have not seen any real defects. Just sent back a dust cover that had the printing off-center and crooked, that's the only thing. I hope they keep improving so we can have these inexpensive options.

I can't comment on durability with a high round count, but as a spare it should be great. I know that there are general concerns about NiB finishes so I'm not sure I'd use it as main. I like nitride finish.

Initially I thought the gas rings felt somehow loose or appeared a tad larger than I'm used to, but the bolt rides nice and tight in the carrier and function was flawless.

If anyone cares, it's a 16", carbine gas, and I tried 223 (55gr), 556 M183 (55gr), and AAC 75gr OTM, all without issues.

Regardless of what you think of Ruger LCP, which isn't a perfect pistol, but it certainly is one of the most portable pocket options in 380. But it stinks to shoot. Now, I don't mind a few mags but is that enough practice? I don't think so.

I have two LCP's with the stainless slide and aluminum trigger. Couple hundred rounds through both at this point, some without the Hogue grip, some with. I have another Hogue grip on order. The idea is to use one for practicing, while carrying the other.

Anyway, beyond a couple of mags I was getting a bloody thumb knuckle on my strong hand, and it wasn't slide bite. It's just from recoil, and from how it sits in my hand. It's not even just bloody, it's a nasty blister that feels like a burn. So I ordered the Hogue after the first session. And it's definitely much better. I would also say that 7-round mags are a must, too.

The sole negative review here that claims it takes an expert to install is just silly. Afraid of undoing a plastic knob and driving out a pin? Pfft. Look up a Youtube video, it's easy as chips. And the pin that holds the Hogue grip in place keeps it from sliding off and potentially blocking your mag. It's a great grip.

P.S. I believe the photo here is wrong, but the part number is correct. I went by part number and got the right item.

Ok quality, crappy design. Might be ok with rimfire, but otherwise it is not usable. Won't stay attached, especially as it fills up with brass, so then it'll pull away and block ejection and cause stoppages. Should have just bought the proper catcher.

I wanted a spare BCG for my budget Diamondback DB15, a basic one. This one appears to be about the same quality as stock. I put 120 rounds through it just to test function, basic 55gr FMJ from several makes. No issues, except 1 or 2 FTF, which might be the mags, ammo or the parts just breaking in. I had the same 1 or 2 FTF on another BCG of similar quality that I tested. No scratches on the face of the buffer, everything fits nicely, no sharp edges or burrs, or apparent tool marks, bolt is tight in the carrier as it should be. Extractor has the little rubber donut washer on the spring.
Having spare small parts is nice, but having a spare full BCG is even nicer. Great to grab on sale or with a coupon.

P.S. Clean and oil it before using. The grease that comes on it is not a lubricant, it's a metal preservative, like on most guns. Which seems weird on stainless and coated modern parts (nitride, boron, melonite, etc.), there's just no need for it.

I've tried the regular "Warhammer" and they're ok, this gives a bit more purchase on the handle and with a scope you want a bit more anyway vs. milspec. Time will tell as far as reliability and durability, and will update review as needed. I don't use whisper pickles, so can't comment on gas busting performance.
