20" Grendel Build - what length handguard

[bigdaddyflo]

I am building a rifle with a 20" Odin Works barrel and am wanting to see what length handguard others have used for a 20" barrel. I have already eliminated any quad rails since they are too big and bulky. I am trying to keep it light on the front.

I like the longer the better so for my I will go 18 or 20 inch barrel and no less than 15 inch hand guard.
I think I seen an ad for one that was over 16 inches somewhere on the net.

* found it.. 19 inches- (but, dang it is heavy...)

slt makes a 16.5
strike industries makes a 16 or 17
there are some longer ones out there

If you're trying to keep it light, I would go with a 12.5" carbon fiber or slim aluminum and be done.

I've built a lot of different 20" guns, and that combo works out very nicely for lightweight set-ups.

If you have a heavy target barrel, then you can do what you want with extended length.

Thanks for the responses. I am also going to suppress the rifle so it will have even more weight out front - I just want to keep it as light as I can and still look good/cool. No one want to shoot an ugly rifle!

Just a thought, if you ever intend to use a Magnetospeed chrono, there might not be any room to clamp on barrel with an extra long hand guard. Only option is removal or a free standing chrono. Have AR319 Lilja and 15" SLR and it's a close fit.

Longest handguard I've seen is 19". I'm trying to keep the rifle light so I am leaning towards 15" - may possibly go as long as 17". This would leave 3"-5" of the barrel exposed - minus the QD-supressor mount. However, I personally won't be clamping on a Magnetospeed chrono - dont know for sure, but have heard it changes POI. I have a good free standing - shoot through chronograph.

I am planning on 15" for my 20" rifle. Just cover up the gas block without going much farther.

here is a 15" carbon fiber $99

Carbon is cool looking and light but, if it doesn't have Mlok or pic rail for a bipod attachment and sling mount, I don't want it.

[bigdaddyflo]

4.44 oz. - wow, that is super light! But there is no place to mount a bi-pod when shooting on the bench. I am looking at 15" slim handguards - just haven't decided on which one looks the best - or even which one to get - any suggestions?
I saw this 15" one and thought it looked very unique...and it's 7 oz., but it's $399. A little more than I want to spend on a handguard.

I like the UTG Pro Slim in FDE myself-

Or the M.I lightweight 15 inch (9.3oz with barrel nut)-

I have a 300 BO with the 15" UTG Pro Slim, but black - and I do like it - especially with the suppressor installed. I was wanting to do something different than that. I do like the Midwest Industries and may eventually go that route.

You could always go Odin Works to keep it in the family. These look pretty sweet, and 7 ounces ain't bad...the keymod version is only 6.7 ounces.

I have looked at buying this one in the past! And it is a good looking guard. I just wish it didn't have the front built in top rail - kind of looks like a rhino! I may eventually go with this to keep it "in the family".
