For that price, they can get new DMR, shooting much more accurately. Lmoa.

I have a question, is this some RFI, or some Vendor's presentation, or did army buy it?
im putting my money on the presentation, but its been 2 years since the announcement of the upgrades, on the dmr didn't some rr jawans use sig 716,they might have some sig 716 as some de facto dmr in some units

m16 converted to a sniper, its 5.56 tho(main problem) but is fielded as standard across philipino marines,it saw extensive use in marai and zamboanaga siege(some Islamist group rebelling in a city tho not Isis related)
Wouldn't converting sigs be better? Its got a bigger calliber

Have you guys seen the new bcg from law tactical?
They chopped down the milspec bcg and strapped twin recoil springs,to make the ar rifle foldable.


Reliability factor is still a concern,but it helps the user to modify existing internal piston/DI rifle.




But,i gotta admit,there were similar(esque) attempts to make short bcg's but it had little takers due to many concerns,anyway its a cool product nevertheless.

It is called "Bufferless AR", This is cool idea but sadly it won't have many takers like other similar designs of past-present; most successful of them being current gen SIG SAUER MCX which is similar to this in practice; and previously there existed a designer named Allen 'Al' Zita who made his own fork of Stoner pattern DI system with extended gas key overlaping (modified) gas tube - so when fired it would not have a cut out between the two and hence no bleeding of remaining gases inside the receiver - keeping it a bit cleaner than before; and in this design he moved recoil spring forward and cut down conventional AR bolt carrier in half
am talking about ZM Arms LR-300 (which later got sold to other arms manufacturers and they gave it new names etc)

an entire post on LR-300 from my side
you mean a DI MCX-ish-AR-15 with folding buttstock ?

easy peasy but it would kinda imbalance centre of mass (or is it called centre of gravity ?) on AR design (one reason AK ;muzzle climbs; a lot is because a relatively heavy bolt carrier moves violantly back and forth inside a lightweight, hollow receiver; in general true for other designs too in their respective ways)

the ;most near; thing to this design existed in something named LR-300 rifle from a designer named Allan 'Al' Zita,

the principle idea behind this design was to eliminate the opening of gas port between gas tube and gas key that occurs in AR design when it cycles, leaving out much unburnt carbon residue inside the receiver itself etc,

so Zita just played reverse uno card and lengthened gas key and shortened gas tube, shifting the overlapping of both outside receiver and above barrel, while at same time also shifted recoil spring system at front, on the gas key itself,

this new gas system that he named "delayed impingement" and this arrangement also removed necessity of recoil spring system behind bolt carrier so he could ;shorten; it there (practically he just cut bolt carrier in half, leaving only necessray front part)

end result = this

which also gave this folding+adjustable length buttstock of his own design, but any modern AR style buttstock could be thrown on it
View attachment 122665
also, change in trigger group since rear side of the bolt carrier hits on auto sear etc, elimination of that part required something new and Zita simply adopted an AK-auto sear like lever arrangement that would be actuated by AK-type auto sear cut on the receiver and it would further actuate AR style auto-sear etc...

So did it work ?
yes
then why didn't it got much success ?
because Al Zita was perhaps "too early", what i'm saying is he designed and started manufacturing it-selling it on small scale in early 2000s, back then gun market in the US was passing through a stagnation with not much on offer to consumers and their 'needs' were mostly covered by already prevalent AR style firearms so why bother with a new 'fancy' design ?

later Zita sold off this design to certain Para Ordnance that relaunched this rifle with picatiny rails and stuff with new tag but again, faced same fate,
from here it is said that design further was sold to some new company that decided not to manufacture it and kept sitting on it without doing anything, from there Zita got his original design back (i.e. got rights over it) and....he also is mostly doing same ? not doing much with it ?

anyway just saying what you're asking is indeed possible and there existed one working design that shown ;proof of concept; of such idea (albeit with slightly different gas system and recoil system etc but still)...so yeah

in case of SIG MCX, doing what @Lonewarrior mentioned in some clever engineering way would be the way to bring DI pattern gas system for MCX design

BTW another sidenote, just as this topic is brought,

very early Armalite AR-12 design i.e. 7.62 NATO rifle that Stoner started working on after AR-10,
this rifle also was practically going to become a DI gas system rifle with wrapped recoil springs around bolt carrier thus giving a design that could easily be adopted for folding stock variant etc; the main idea behind the design was to make a stamped sheet receiver design for ease of manufacturing etc,

later when AR-15 was sold to Colt, stoner switched from DI to his own short stroke gas piston system on this AR-12 and further it became AR-16 (NOT TO BE CONFUSED WITH ANY M16) and later scaled down version of AR-16 became AR-18 etc...
It is said that Stoner just dropped idea of utilising DI gas system after those vietnam era issues started bugging his mind and of course he lost design to Colt and so, otherwise who knows even AR-18 could have been a DI like rifle...but chalo jo hua achcha hua with that we at least have this huge family of AR-18 derivatives that comprises of short-stroke gas piston system rifles with stoner-pattern multi-lug rotating bolt system...
Coming back to the Law Tactical ARIC, i like the fact that they designed it so it could be adopted with any existing standard AR that was seemingly not possible with LR-300 (required its own upper receiver) and SIG SAUER MCX (a wholly new AR derivative with its own upper and lower receivers) , however they had to compromise here as well for e.g. it seems it doesn't have those saw-toothed cutouts on it that would allow Bolt Forward feature and hence this used with regular AR pattern receiver that Bolt Assist button would go dud - though if this tradeoff comes at benefit of having an AR that can be opened up easily without getting lockup of bolt carrier between upper and lower receivers (common issue with conventional AR design) then perhaps yeah good idea
also i kinda not like this fact that the channel-like cutout made for accomodating recoil spring guide rods on both side - simply because i see a possibility of outside kachraa getting accumulated there and obstructing movements-causing jams etc; they rather should have at least kept right side one (where ejection side is) covered i think

overall nice idea
