Slowly losing interest in the 308 build due to lack of rail options

KCode · Nov 4, 2023

I don't have any 308 ARs and I have been wanting one. But I cannot find a single rail that I like.

The build will be a Windham Weaponry AR 308 (DPMS high I believe) and I already have the lower and upper.

All I want is a nice traditional 15 inch Mlok or picatinny. It seems any I find are some that look like chain length or dumb angles.

Want something like this (traditional)

Don't want something like this

I thought diamondback did, but they don’t.
Would this one from Palmetto State work?

I actually like that one! I like how overall it is symmetrical.

I really like the PSA M110 rail but you can't buy it

Snap the Magpul rail covers on it.

You could dump that upper receiver for $150 and have this for basically a $100 upgrade over the cost of a decent rail ($300).

MEGA AR15 MML Billet Upper Receiver with 16" M-LOK Handguard | ZEV Technologies

ZEV Technologies MEGA AR15 MML billet upper receiver with 16in M-LOK® handguard.

www.zevtechnologies.com

The Mega is good shit and you can get the 14” for a little less. If it’s gotta be 15” then buy the 16” and send it to @chevy_man for shortening.

That gets you the Mlok style you want and you’re getting a top tier receiver set that the HG doesn’t bolt to the barrel nut for not a lot of money more.

If you're considering designs like the PRI, I'd look at the Apex Gator Grip. You order the appropriate rails separately.

Cheap out on receivers and then spend $900 on some sub par dress up for a look. Let me guess, BA barrel?

That’s not even close to the original style you posted a pic of either.

I was done at "Too see throughy". I just can't work with those guidelines.
BA barrels are more times than not damn great shooters. You would know this if you had any experience with them!

Cheap on receivers? Which receivers shoot better than the others? Can you post some links and data?

wilson combat are normal looking but I think "high" profile so should be OK with Aero but not OK with most DPMS

Bigfatcock · Nov 4, 2023

Quad rail or gtfo.

B y r o n · Nov 4, 2023

If you want full length rail then M5 Atlas R-One or if you just want rail front and rear then Aero Precision S-One.

bigjake83 · Nov 4, 2023

I really enjoy the feel of the MEGA upper and Zev handguards, rock solid and enough room to fit .875 AGB without issue.

The Maten and Zev receiver set's are excellent for budget builds.

Deepwoods · Nov 4, 2023

I will second, or third, the ZEV/ Mega upper. I have both small and large frame versions and the fit and finish is very nice. The anodizing is done very well.

The small frame hand guard fits my mediums hands well, while the large frame is just within comfort for me (and larger than the LMT in OP).

I think your second "do not like" is an SLR Rifleworks model. They do have a lot of options, some of which are full rail, full MLOK. I did a build with their newer ZRO 15.2" model and it turned out very well.

So BA barrel and PSA parts kit it is then.

pmclaine · Nov 4, 2023

Get an LMT handguard.

The upper comes with it free but you may have to work your barrel a bit.

Have you looked at the Geissle mk7?

thehun · Nov 16, 2023

My Aero M5 setup with a 22" Criterior M118LR shoots ball like a freakin' champ ... Aero M5 with the ATLAS R-One handguard is a really good setup ...

If you can find a Criterion barrel ... run that ... they are stupid accurate ... gassed awesome ... but for the love ... DO NOT buy a BA barrel ... their quality control is all over the place (even though they are owned by Aero ... BA is a hit and miss sadly) ...

FatBoy · Nov 16, 2023

The description threw me. The Armalites CMP rifles have them and when I was cross searching the Mk7 popped up. My bad, It’s for M4 receivers, not tall large frames. They should update the description as most AR shooters don’t think of a quad rail and a small frame SR.

I’ll keep looking. Someone makes one.

Samson makes one

From a purely Aesthetic standpoint, this is my favorite high pattern large frame rail. Unfortunately this is no longer made. The newer version has M-lock instead, still very nice + the integrated QD sockets.

They were a Camp Perry run. One rail, but different nuts for SR-25 and AR-10 thread pitch.

The new longer version is a component of the current USSOCOM Mid Range Gas Gun.

Yeah but we can’t get them so it’s really a non-option …

One of the costs of selling to Uncle Sam is blem rejects.

Geissele's standards are exceptionally high. Every once in a while (major holidays) he'll laser-mark blems for deep discount. I wouldn't be surprised when eventually these rails hit the market.

Sometimes it pays to go to Camp Perry to see what he sells only to competitors on Commercial Row.

Bill got started selling his National Match triggers. Without an advertising budget the reviews passed by word-of-mouth.
