SLR 8" SBR build done. Just waiting for a few accessories (sling end plate, AAC Blast Shield, Cloud Defensive LCS, and an actual working ScoutLight head) and repairing my BTC Spectre, but otherwise al

One of my latest build, a real Colt M16A1 converted for GBBR on the WA system. Stripped upper, barrel and BCG was changed to Viper Tech du to my local laws. Also a video of how it was made:

Question for the experts:

 

I have a DTW coming next week and I will probably be building a DMR upper from it or build a new one from scratch, so I would like to know which 16" DMRs are issued to USA military units. Would a DD 9.5" rail + 16" barrel be kosher? or it will be easier and equally accepted buying the M16A4 they sell, swap uppers and call it a day?

 

My main concern here is that I want it to look military issued and not civi built.

 

Gun pr0n pics are welcome :P

Well, 16" barrels are not mandatory, 14.5" are easier to get hold of but here in spain, fields are a bit anal with "your DMRs must be real issued" or something similar depending on the field owner. Thats why I try to minimize the chances for them to complain and start an argument they cant intelectually win.

 

I heard the 16 inchers are usually issued to special forces along the SPR Mod1, but I dont know how long this rail and barrel are for the mod1, not to mention where to find the parts compatible with the DTW at a price not higher than a full M16A4 DTW gun

I don't think anyone really use 16" DMRs anymore. You'll see a lot of 14.5" ones with 12" RIS IIs in MARSOC. SEAL RECCE rifles have been reported to be 14.5" or 16" barrels with 12" RIS IIs, but definitely not 9.5" rails. I would post pics if I had them, but finding good SEAL RECCE rifle pics is a burden in itself.

In my opinion, if your considering a Mk12 Mod1, an 18" barrel and a KAC FF-RAS would be closest to spec. Although there may be variants (I believe the one confirmed photo of the Navy Recce showed a 16" barrel under the KAC RAS), it's my understanding that 18" barrels with KAC or PRI hand guards seems to be accepted as being "more correct" for Mk12's. There are quite a few confirmed military photos showing them in that configuration.

 

In the real gun world, I'm not certain how effective shooting 77gr through a 14.5" SOCOM barrel would be.

Hawaiianjuggernaught got me an R/S Ergo F93 stock, thusly making my MRP officially complete. Well, I'd like to change the optic to a Vortex Sparc, but I'm poor. 

 

 

 

I adore that  :wub:

My inner OCD self is saying that the world will implode if you don't match an Ergo pistol grip with that.

Also, the SPARC isn't as great as the STRIKEFIRE and cheaper to boot.

See I've got an R/S Ergo grip in black, but it's just not OD! That, and the storage compartment in the MOE grip is quite handy - I keep an inert .223 and a bag of sour skittles in it for emergencies. Still, definitely the nicest Airsoft gun I've ever owned, totally worth the money! Although the Prime hop unit it came with was a nightmare, the Iron Airsoft one I bought wouldn't seal at all, and it's now running a bog standard G&P one I've fixed for .3's... Oh well.

 

 

I'm not a fan of that stock...but that build looks awesome.

 

Thanks man - I was considering a UBR, but a PTS UBR is about £150 if I can even find one in OD, and the F93 stock was £137, including shipping to Josh, from Josh to me, and a small fee for the favour.. Plus, I can't remember seeing an F93 stock in a game so I figured it'd be a bit original, and I've really fallen in love with it since installing it!

Do you know what Prime hop chamber you were having problems with? Did it have sealing problems like the IA one? Also, was the IA one a version 2? Thanks.

The one I had issues with was the Prime WA barrel rear adjust chamber - The stock rubber was a bit too hard for the FPS I'm running, so I went to change it - Unfortunately, the front and rear halves of the unit were fitted so tightly together they couldn't be separated, at least without a specialist tool. Trying to pry the two halves of the unit apart damaged it beyond repair unfortunately.

 

The Iron Airsoft one was indeed the latest type - 1004G I believe is the product code. Despite numerous different buckings, I couldn't get it to seal at all - The BB's were dropping feet in front of the muzzle, which was somewhat irritating to say the least!

 

Saying that, the Prime WA barrel type unit fitted and sealed nicely, so the next step is to save up a little and try the Prime AEG compatible unit, unless anyone has any better ideas...

Exact same problem with the prime chamber I had. That and the fact that recoil un-adjusted it no matter what I did.

 

In the end I just went for a stock g&P hop chamber and bucking, which works well.

Thanks for the info guys, I recently found what seems to be the G&D webpage and this version of the DTW, with what seems to be a 12" rail and 12" barrel?

 

Maybe im in luck and it will be released before my patience runs out ^_^

Nope. It's just DD M4A1 RIS II on 14,5 inch barrel.

Excuse me, I'm going to run to the bathroom for a minute. This and kagami's Chinadoll builds are the only rifles 'modern'-looking enough for me to suit the 93-style stocks. The OD furniture is just... Yeah I'm going back to the bathroom.

Nah. The 'Ergo' stock is originally a MagPul design (as the M93B) and suits the MagPul grip.

...

I see...did they use some sort of adhesive to keep the halves together? I was using the PRIME AEG barrel hop chamber and was easy to disassemble, but I found it a bit difficult to adjust. A slight turn causes a big difference in hop. I was using a Prometheus green hop and Firefly nub (the "flat hop" one), .25g shooting at 1J. I'm not certain if its because of the rubber combination that's making things difficult for me...or it just needs more power?

 

It came loose from recoil? That sounds odd...i have opposite problem where its a bit tough to turn. We are talking about the one were you turn the set screw to adjust?

 

Yes, the 1004G is the newest one. I found the design is nearly identical to PRIME (with the exception of the adjustment wheel) so it's odd that it doesn't work.

See it could well have been the recoil loosening the adjustment on mine, as occasionally I'd get laser accurate shots, sometimes no hop, sometimes overhop. I found it very inconsistent, but I thought that may have been down to the bucking in it... Either way, it's binned now! I'm using the stock G&P chamber as well, but due to the design of the MRP barrel I can't adjust it at all - I've got it flying .3's quite well at the moment, but it's annoying not being able to fine tune it.

Heh, I feel honoured! :P It's literally my pride and joy, so nice to know other people appreciate it :)

Not that I could tell; I'd read a few similar stories on GGI that Prime hop units were machine with exacting tolerances, so my guess is on my particular unit the parts were so well fitted they just sort of press-fitted themselves together. I'm entirely willing to accept that it was a lemon, but it definitely wasn't coming apart. 

 

As for the IA unit, I tried two different barrels (Stock G&P and a stock G&G), and a few different buckings - I just couldn't find a combination that sealed well. I'm not at all sure why, I tried PTFE tape everywhere I could think of, all sorts of things and just couldn't get it going right. Could well be the MRP barrel and extension causing issues, but I tested the same setups in a standard WOC and had no luck either! Very strange, and disappointing as it seemed like a really well made piece of kit.

 

Either way, the plan now is to try the Prime AEG unit, and if that doesn't go as planned, I'll try every system I can find until I get something I'm happy with - The stock G&P is doing well for now, but the inability to adjust it is going to get old rather quickly..

IF I were to speculate what was happening with mine, I'd say that the recoil pushed the part that's spring loaded of the hop unit forward, just for a moment, decreasing pressure on the rubber and allowing the BB to seat itself at random depths of the hop rubber's notch.

 

Being a user of the Madbull Noveske rail myself, yes, it's VERY annoying.
