Can someone confirm any in spec grendel bolt will properly function in a Bootleg adjustable carrier? There's nothing special about the bolt that allows adjustment, correct? Thanks.
 
That is correct, any "mil spec" bolt will fit. I'm using a Bootleg carrier in my Grendel, and I forget who's bolt but my other 5.56 and 6.8 bolts also fit just fine.

I do recommend using some other (like adjustable gas block) method of tuning the gas unsuppressed, and using the Bootleg carrier adjustment to switch between suppressed and unsuppressed. It has the right amount of adjustment for that, but if you are hoping to install it on an overgassed rifle and use the carrier alone to tune for both suppressed and unsuppressed, you may be disappointed.

Apparently there are different Grendel bolts now (somebody just HAD to fuck with it!) so be sure you have the right one. I'm not familiar with this particular carrier, I usually just use JP Ent. full mass --there isn't a better carrier IMO and their bolts are pretty nice too. Think they come in Grendel now. But if one bolt works then any other based on the milspec design should too.

Anyway, I got my bolts from AA way back when Obama was fucking with prices, and there's a different bolt for the Grendel and Beowulf too, I think it's just the extractor, but they are separate.

I do know having the right bolt in there matters. I had the wrong bolt in one a long time ago, I forget all the specifics, but basically it just didn't work right, constant malfunctions one after the other. And if you have the wrong extractor in one, it'll malfunction too.
 
I would agree with yond. I have the bootleg carrier and rifle shoots great on unsup. but one click towards sup. and it was not picking up rds out of the magazine. It is too much an adjustment I think to try and tune a rifle. I assume it works well with supressors.

There are .125 and .136 bolt face depths, and then chambers cut to match one or the other. Obviously mismatching will cause either tight or very loose headspace condition.
 
Do y'all have standard or light weight carriers? I've always used m16 carriers but see a lot of folks like reduced weight. Thanks.

I thought Bootleg only made a standard weight adjustable carrier? That is what I'm using. I'm not aware of anyone making a lightweight adjustable carrier, other than having a shop do custom work on something like a Bootleg or Gemtech.

I have machined and use lightweight carriers in a number of my ARs, but don't see much advantage if suppressed use is your goal.

What are you wanting the adjustable carrier for? That might help us give you worthwhile suggestions.
 
I believe Bootleg makes a standard and low mass.

It's for a 12" Grendel. Pretty much an all round compact with more punch than 556. Either 1-6/8 or 2-10 scope. Reliability trumps lower recoil for my uses. Thanks.
 
Where did you see low mass Bootleg adjustable carriers? According to their website they only have one adjustable carrier, and it's a standard "M16" weight.

Is your 12" Grendel suppressed some of the time? That is the application for this carrier and it works really well for that role. If you're not going to use a suppressor, and are just hoping to tune the rifle, go with an adjustable gas block instead, the carrier won't do what you're looking for.

Mine is a 12.5" Grendel as well, with the Bootleg carrier for suppressed and unsuppressed settings, and an adjustable gas block for initial tuning unsuppressed. I'm using a 3-9x mil dot in a 20 MOA mount on mine; it's a good setup even at reasonably long range. You're right that it's an excellent "all around" gun; I've come to like it better than my 5.56 stuff for something to grab when I head outdoors.
