Just received my X-Caliber 18” Grendel barrel and bolt. Even with them cerakoting it still showed up in 5 weeks! They quoted 2 months.
Hopefully in the next month I’ll have everything else ready for assembly. Not sure the Vltor MUR upper will benefit from face truing, but I’m going to have Paladin do it anyways. |

Hey guys. Looking to do my first 6.5 build. Thinking of getting a sbr type see what it can do. Anyone try a SBR barrel from Alexander Arms? Looks like a good price or does anyone have any they would recommend. Thanks all

My backup gas gun competition rifle has been sitting around without a barrel, and I had store credit at Rainier, so I’m deciding to give the Grendel a try.
I grabbed the 22” criterion and installed it today. Attached File Mega MML receiver set Gemtech carrier JP SCS Gessiele High Speed I just picked up the TBAC bipod and will give that a try as well. I found a box of Hornady 123 SST and 123 AMAX (I don’t know why I had Grendel ammo lying around). Goal for this rifle is more of a fun gun and occasional backup to my 6.5 Creedmoor while shooting Gas Gun division of PRS matches. I’m really hoping I can get away with not having to load for this thing. Any recommendations on high quality factory ammo? If I ever have to resort to this rifle in a match, bad things have already happened so I understand I’m not going to get the performance of a large frame. But something with decent velocity, accuracy, and velocity consistency is a must. |

I use a JP SCS in my 18", though I exclusively use E-lander mags. It's worked great for me.

Bolt is dropped. Only thing holding it from going forward is friction of the bullet on the feed ramp. Hard to see from picture but bullet tip is NOT contacting back of barrel. Plastic tip is completely intact when I pulled it out. Springco red installed. It’s definitely the feed ramps. Actually the feed ramps on this barrel are the worst I’ve ever seen, and I’ve built a lot of rifles. I’ve seen a $65 radical firearms Barrel with a better feed ramp than this. I’m going to take to range again and fire it single shot. Loading round into chamber by hand. If it’s decently accurate, I’ll polish the ramps. If not, it’s going back. |

View Quote My Grendels RUN crazy-reliable. But I will say every once in a while, in a completely full mag (maximum force against the lips), when I insert and drop the bolt manually on that first round (without benefit of the gun-jarring motion of a fired gun cycling) - sometimes I have to tap the BFA to get the bolt to finish stripping the round. When actually firing, I never have a problem. I'm close to 3000 rounds in by now, steel, brass, you name it. I run E-Lander and ACS mags. |

Got out to the range to try again. First group was 5 rounds single loaded. I slid the round into the chamber by hand and dropped the bolt on it. Sub MOA. Ok so the barrel itself is fine.
Then tried cycling and everything went to shit. The rounds that did chamber shot into about 3 MOA. They were getting beat to shit when chambering. This is a round that actually chambered but I unchambered instead of firing. Attached File Aside from the severely dented case, the bullets themselves are heavily gouged. To a point where I would suspect would have an impact at long range. The plan was to take a dremel to the feed ramps and polish them, but I’m not sure if that will be enough in this case. I still haven’t tried other mags yet. |
