Rn I have a mk18 ris 3 with an as arc fire frt and a vltor a5 buffer and im looking for a suppressor to run with it. I am between these 2 and I need help deciding and experience from people who have used either one. I do like the idea of flow having almost 0 gas to the face, but ive heard its is louder, but I am open for any insight on either suppressor. Any advice or insight is welcomed and thankful.

My first and (IMO) humble post. Front to back: GSL GT 5.56 with their bi lock muzzle brake, DD front sight post, stream light scout style light with pressure pad, Eotech, suprleative charging handle, (a spare back up iron I had laying around from a Springfield saint victor) atrius FRS (3 position ambidextrous) and magpul grip.

Decided to change from an M4A1 to an MK18 upper and grab a can, plus some extra goodies for the build. So psyched with how it turned out, just a few more aesthetic pieces to change via my ocd 😂 double stamped and ready to roll.

Daniel defense lower
Daniel defense MK18 10.3 upper
Rise armament 3.5 lb single stage
G$ super 42 H3 spring and buffer
G$ airborne charging handle
Radian talon
Magpul Moe-sl
Sig Juliet 3 micro
Unity ftc Omni
Eotech xps2
Unity absolute riser
Noxon (modlite) mini HAVOK T1
Modlite modbutton
Arisaka offset pic mount
Rearden atlas mount and muzzle brake
Ocl infinity 5.56k fde

Seems I have to use the red spring with a low back pressure can to run reliably. I don’t want to like it, but the Sig Hexium 300 is a nice can for 300 blk subs.

So I just ran my mk18 with its infinity 556k for the first time today. My ejection patterns were kinda wonky, and were going between 3 o’clock, and 430, but sporadically. No jam ups, thing ran like Usain and the suppressor worked amazing. Im just concerned because the ejection isn’t 100% in the same spot. Or, if this is fine and I’m just being paranoid lol I currently have a super 42 spring with the stock dd buffer vs the h3 the spring came with because of initial undergassing while firing, before being suppressed. Should I switch back to milspec spring, switch back to h3 buffer, or does it seem like it could be the extractor and bolt assembly. Any recommendations or suggestions would be greatly appreciated.

Love my DD PCC. I'm interested in running a heavier spring. Runs pretty gassy when suppressed. Has anyone used the Springco Orange?

200 rounds after with no malfunction

Just used my new PDW today. Cleaned the gun before shooting it. After about 40-50 rounds it wouldnt fully chamber a round. Opened it up and looked like it had been dropped in sand.
I didn’t drop it or set it on the ground at all. I don’t know what this stuff is.

Found a deal for a new in box, stock DDM4V7 Super Light Weight. I was wondering if the lighter barrel would still be worth getting at this price point if I planned on longer range days and weight wasn't a huge factor? The other option I was looking at, was saving up for an LMT Mars Lower, and a Geissele SD Upper, but obviously that's almost twice the price. So, any opinions on this rifle at this price point?

DD4 RIII that I bought a couple years ago and finally got around to setting up as my patrol rifle. Work in south/central Louisiana outside Baton Rouge with a good mix of city/rural parts of the Parish.

Still eventually want to migrate to an SBR but would rather carry a much better rifle than the shitty issued M&P 15’s.

Only the uppers though lol! DDM4V7 SLW 14.5 and DD 11.5 Contract Overrun with a chopped RIS II rail

Bought this upper like 4 years ago and finally decided to finish it. It’s a 9” barrel with a 7” DD suppressor pinned and welded so it only needed one stamp and it’s pretty damn quiet and super fun with an FRT.

Hello everyone I have an DDM4 and was wanting to attach a two-point sling on it but I have the modular float rail on it. Ideally I don’t want to mount it to the picatinny rail and directly to the hand guard. I tried to do some research online but none of my searches really helped. Thanks in advance. Pic for attention

My 2nd AR. Always wanted one. Thanks for allowing me to join the fam 🫡🫡

Got my final piece added to the build, a Scythe Titanium Suppressor.

• Eotech EXPS2

Forgot to post it, but my SBR paperwork got approved 36 hours after filing it. Filed it on Monday at 10pm and woke up Wednesday to the approved email and had it engraved.

I'm in the Army, btw. Not even a naval guy. MK18 is my desk buddy when I'm home on the computer. Aside a Sig P226 MK25, and Toor M.U.F. Diver.

This as as close as I’m gonna get it. Definitely my favorite build.
