I am almost done with my 6.5 Grendel build. It started on a whim when I found a 20" 1-8" twist stainless barrel on sale at the same time a local FFL had new Noreen lowers on sale for $50.
I'm running the Luth MBA-1 stock as I want the adjustments that it offers. I am also going to run my AAC M4-2000 suppressor. AIM had a sale a while back on a single stage adjustable trigger and I decided to use it on this rifle along with an adjustable gas block. It's already assembled, I'm just waiting for a few parts to show up to put the finishing touches on it. |

nice my other grendel is a 20 and ive been doing alot of long range stuff with it 1850y so far that about the limit with it though . the 8+ week wait on my new barrel for this build is killing me though , rest of my parts for the build except for a trigger will be here next week hopefully . . almost got my hands on a high speed national match trigger for a good price , but thinking i may just find the lightest single stage trigger i can find instead since im usied to single stage triggers

The below is an excerpt from something Criterion Barrels put out recently. While I'm not an expert, this made a lot of sense to me.

That makes sense, and of course you can build your gun your way. It was just information I hadn't entertained, and was therefore glad to have. Good luck!

If you want a great trigger, look at the Trigger Tech Diamond trigger.

I've bought a lot of McGowen barrels including 1-off custom ones, they are pretty good at letting you know the limitations of their barrels--I would ask them what they think about your "topology." On the other hand, having dealt with them enough times, I'm going to assume they raised the gas balancing issues with you already. Looks like you're outfitting for a silencer as well. 28" hbar is a lot of mama jama weight hanging out there!
I bought a couple of those luth ar stocks and can't stand them--but to each their own as they say. I think by and large AR buttstocks have become "pimp shows" and in the process most of them can't even do the basic job of staying movement-free.

I'll be interested to see how this pans out. I handled a 24" grendel at a gun show and that was what convinced me to build a Grendel. I'm really excited to see where this beast goes.
I really don't think you'll be happy with the Luth stock, unless you want to buy mine for the NIB price . More seriously - I don't think you are building a practical gun. You are building this gun because you think it will spark joy inside you, and because you are attracted to the challenge of ELR with a Grendel. But since this gun isn't about getting max performance for minimum dollar, I wouldn't cheap out on the stock.

yeah ill decide on something down the road we all know i can shoot witht he cheap stock i have on my 20 as it is lol (34$)
infact i like it so much i run it on all my ar's i wouldnt mind something with an adjustable cheek rest though as with my 30 moa rail it raises my scope up .5 inch. i shuold just buy some 20/30 moa rings, but that means swaping rings everytime i wanna go night hunting, witht he rail i dont have to do that Last edited by mel80; October 30, 2020 at 10:06 AM. |

My McGowen barrels have always been great shooters.

got some chrono time in today
First up is 123g eld-m over 27.7g of ar comp Out of the 20 there's are shooting on average 2620fps Out of the 28 I just got a string of 2792-2806fps Next test 130 and 135's in my 20 the 130's average 2580-2600fps im expecting a solid 2800-2850fps out of the 28 inch barrel , this thing is just slighlty slower then my 22" creedmoor and i suspect as i break the barrel in and work up my powder load specifically for this barrel that speed gap will be very minor , atm im launching 123g pills out of the cm at 2950fps |

i may end up with a low mass bcg after all .
suppressed the rifle cycles perfectly unsuppressed it short strokes , first thing im going to try is a std carbine buffer and spring , im running this 28" upper on my 20's lower which runs a h2 buffer and heavy spring which runs flawlessly on with the rifle lenght gas system on the 20" barrel both suppressed and unsuppressed on monday ill have a std carbine setup in my hands |
