M14 Bullpup ~ The evolution continues

SR420 · November 3, 2011, 02:34 PM

My bullpup M14 conversion continues to evolve...

Configurations that I have tried:

I have used the my Mod 1 type SEI barreled action in this chassis, it has a light weight 18" barrel.
I have used the my Mod 0 type SEI barreled action in this chassis, it has a sub MOA medium heavy weight 18" barrel.
* The overall length of any 18.0" barreled action equipped with a DC Vortex is 28.25" in this chassis.
I have tried the Magpul AFG, Grip-pod, Tango down and Atlas bipods.
I tried TROY Micro folding battle sights... they are too short for this application.
The 29" Blackhawk Homeland Security Discreet Case and 7.62mm hook & loop 3 mag shingle that I purchased separately are perfect.

Optics:

I tried an XR308 from EOTech and a Leupold Mark 4 1.5-5x20mm MR/T with an offset MRDS.
* The offset MRDS is a total waste of time on this chassis, but it is awesome on my SAGE EBRs

Modifications/Changes:

My first modification:

In an effort to improve the feel and usefulness of the factory trigger pad I used the outline of my M14HDW.US V2 EBR trigger shoe and a file to reshape the original trigger pad.
I was somewhat successful, but it could be better.

* Soon after I informed the manufacturer that I had modified my trigger pad they quickly found a reason to initiate product improvement #2 and lowered the trigger pad... I don't know if they have rounded off the sharp bottom edge though because the manufacturer is dragging there feet about sending me some new replacement trigger pads

* Also, I complied with an earlier request to distributors by the manufacturer to swap out the rear brackets for new ones to solve some fitment issues - mine fit fine, but I replaced it and the brackets on stocks I have in inventory. This was product improvement #1 and it went smoothly.

The next modifications:

After I addressed the trigger pad I focused my attention on mag changes.

I had a SADLAK tactical mag release installed.
IMHO, this is a must have item for all owners of this chassis... reaching back and behind the mag body to release the mag is much easier with the SADLAK part.
I also replaced the original pistol grip with a Magpul MIAD.
I have large hands and the grip change provides me with a bit more room to rock the mags in and out of the receiver.

More changes:

The CQB-16 barreled action that SEI built for me earlier this year is now in my bullpup M14 chassis. It has a 16.25" light weight barrel.
* The overall length of any 16.25" barrel equipped with a DC Vortex or Comp is 27.75" in this chassis.

Bullpup CQB-16 optics:

I am currently using the following mix of sighting kit.
Magpul MBUS - Gen II, LaRue Tactical LT608, Aimpoint CompC-2X 2MOA, EOTech FTS 3X magnifier - Gen II.
* The MBUS required some work with a file to fit... this was an easy modification.

* I own several M14s with SAGE EBRs being my favorite and I understand that it's an odd niche that would ever consider converting an M14/M1A into a bullpup. Let me know if you fit into that odd niche, I can help.

Stay tuned, this compact blaster is growing on me fast and I have completed additional modifications plus I'm currently working on more modifications & upgrades for this chassis.

How is it that you are fortunate enough to own M14's?

Ex or current military? I didn't think any of them were transferable NFA, but I know relatively little about machine guns...

Anyway...I'm jealous even though I don't have a clue about most of the accessories you mentioned with the exception of the Magpul AFG, which I feel is the best ergonomic forward grip I've ever used.

I would never have thought you could wring the same accuracy from a bullpup chassis, but you've proven me wrong on that point in previous posts. Nice weapons.

All of my Norinco and Poly Tech receivers have M14 stamped on their heels.

I wish we could purchase and own real deal, USGI M14s, but that ain't going to happen anytime soon.

SR420 · November 13, 2011, 01:12 PM

JTac has produced a great product, but there is plenty of room for improvements.

.

SR420 · November 14, 2011, 08:05 AM

The question of Federal minimum length came up again... the 16.25" is
back in a SAGE EBR and my standard weight 18.0" is back in the bullpup.
Better muzzle velocity and better safe at home than in Federal prison.

SR420 · December 6, 2011, 11:49 AM

This is how the bullpup M14 looks when lined up with other M14s
Barrel length from L > R: 16.25", 22.0", 18.0", 18.0" and 22.0"

SR420 · January 14, 2012, 06:33 AM

1st picture of the Gen IV SRSS chassis.
Courtesy: Different

It is said to be a full pound lighter than the JTac chassis... competition is good

SR420 · January 21, 2012, 12:27 PM

JTac's new spacer adds two inches of length to the chassis...
this should help you guys meet minimum length requirements...
the spacer also adds 14.20 ounces off weight to the chassis.

PH/CIB · January 21, 2012, 12:54 PM

Incredible looking M1A's,,, have never had a bull pup rifle,,,how is the trigger on the bull pup?

I have the Springfield Armory Scout M1A with the walnut stock,,, rather than a bedding job am leaning towards a Sage EBR or the J. Allen Entprises stock,,,I like the idea of the steel of the receiver mating to metal with no bedding job having to be done and the ability to take it apart without degrading the bedding.

Troy makes a good stock also,,,and there is Lawman484 stocks with laminated wood and he handfits your barrelled receiver to the stock,,,in your experience with the M1A platform which stock will increase accuracy the most,,,and beyond that possibly a rebarrel job to a medium or heavy weight barrel for more accuracy?

DasGuy · January 21, 2012, 01:57 PM

That bullpup M1A looks like something out of a sci-fi movie. I dig it.

Thanks! The trigger is fine (not terrible), but you will notice the extra mechanics to it.

As for accuracy, you have already named the two that I would suggest, JAE & SAGE.
The SAGE EBR is my favorite, it's simple, robust and tends to weigh less than a JAE when all is said and done.
Be sure and check out the PMRI from SAGE, it has a Magpul PRS2 on a proprietary butt stock adapter.

Ripley called, she needs her rifle back.

That's very cool. WAY out of my price range, but very cool.

brian923 · January 21, 2012, 06:52 PM

Im not fortunate enough to have an m1a, but that looks really cool. Just wondering though, hows the trigger and hows the muzzle blast on that thing.... As in being so close to the shooter?

Ridge_Runner_5 · January 21, 2012, 07:45 PM

I've heard the gas system needs to be modified. Can you confirm or deny that?

SR420 · January 21, 2012, 08:25 PM

No gas system modifications needed.

The trigger is fine, but I can tell there is an additional mechanical component.

Muzzle blast: I've only fired it with a sound suppressor.

Are you forgetting this is a bullpup- not an SBR? It just "looks" like it has a short barrel- it doesn't.

The barrel is intermediate length, same as the Scout Squad M1A at 18", not as short as the SOCOM at 16". I don't own one, but from what I understand, only the 16" barrel needs the gas system reworked.

SR420 · February 18, 2012, 11:00 AM

Now with more bullets

Weight?

According to XS-Products their X-14 drum mag weighs 4.9 lbs. loaded with 50 rounds.

The weight of my bullpup with optic and all of the accessories pictured below is just over
14 lbs. empty (no mag in the receiver) and just under 19 lbs. w/50 rounds and the drum mag.

Big Shrek · February 20, 2012, 11:56 PM

Looks like the old Muzzlelite Bullpup stock!
but with a worse trigger...

SR420 · February 21, 2012, 08:37 AM

Big Shrek, I have not yet had the opportunity to try the BullDog 762 you posted a picture of and can't comment on it's trigger.

How long have you had your BD762? Why is the trigger so bad?

SR420 · February 21, 2012, 10:28 AM

H2O's Rogue Modifications & Upgrades

BTW, Dino Brunetti, the National Sales Director for JUGGERNAUT TACTICAL,INC. reluctantly admitted to me that JTac sales have sky rocketed
and it's all due to my spreading the good word online with my positive reviews, detailed pictures, honest evaluations and practical modifications.
It seems that I do a much better job of marketing their product than they have... that's why Dino sought me out in the first place.
Understand that I receive no compensation from JTac for my hard work - nothing, but it is good to know my work is appreciated by the consumer.

Big Shrek · February 22, 2012, 11:20 PM

Actually, I was thinking that the trigger on yours was worse due to the Ugly Factor

That's one ugly trigger...in my view...I prefer a more standard look, like on the Muzzlelite

SR420 · February 23, 2012, 07:12 AM

Understood

Norrick · February 23, 2012, 07:15 AM

SR420 how is the scope mounted on the fourth from the left? It looks like one of the rings attaches to the feeding mouth for the stripper clips.

SR420 · February 23, 2012, 07:21 AM

Complete Bullpup Conversion Kit on GunBroker

Those are EBR rings made by Badger Ordnance.
One sits on a SAGE stripper clip rail and the other sits on the top rail.
It's a 'vintage' set-up that few people use these days, I've replaced it with a CASM. (bottom)

The M-14 bull-pups are gorgeous, and make one quickly forget about M-16s and AK-47s.
