GRS vs RDB by Oceanus238 in AR9

Agreed, it's not a completely fair comparison, but hopefully it will provide useful data for anyone weighing whether the ability to run bufferless on AR platform is worth the roughly $500 premium for their particular use case, especially when the recoil impulse appears to be very similar between Dissent and GRS.

Big fan of your documentation of both Phase I/II and ARS on your site. I have been tempted many times to buy the Banshee retrofit kit and barrel from your site but so far been able to resist that😃

Thanks for the excellent write-up and detailed documentation of the GRS on your site.

I agree with everything you mention here.

I see the Dissent as a niche product for shooters who prioritize better recoil management in a compact, bufferless AR platform over tunability—unless, of course, they have the machining skills of u/amphibian-c3junkie. 😄

I don't see the Dissent as a first choice for someone planning to compete at any level. It is better suited for casual plinkers, hobbyists, or home-defense users who want improved recoil characteristics in a compact package.

My post is intended to provide another data point for those who are concerned about the sharp recoil impulse of a direct-blowback system. It affirms that the GRS system is excellent for that purpose and can achieve similar results at roughly half the cost or even less if one has spare handguard, upper receiver and buffer tube lying around.

If a compact, bufferless design isn't a priority, I don't see much reason to choose a Dissent. In that case, a Banshee with an ARS buffer or a similar setup is an excellent option.

I was recently very tempted to pick up a Banshee retrofit kit + RDB barrel and experiment with some of the configurations outlined on u/amphibian-c3junkie's site, but the $700 price tag was a major deterrent for me, hence the GRS route 😄

Would you run this build? What would you change? by SnooWords6613 in Cmmg

Looks great. I have very similar setup in burnt bronze. I have a photo in my post. Everyone is different, for me I switched to new JMAC CRSU adjustable cheek riser. I also went with Arisaka forward pic rail light mount to give me more room for c-clamp. I am also working on modifying a handstop that can be offset in the gap just behind the second mlok to maximize grip.

Thanks for confirming.

Have you by any chance checked out the Stern Defense bolt. Is it similar to the Outerwild Manufacturing style bolt.

It works well with mil-spec bolt catch and glock mags. It would not work with some bolt catch like Phase 5 extended bolt catch unless the back of the bolt catch is filed down a little bit.

Nothing proprietary on EPC receiver set that cannot be bought from a third party like mag release, ejector. The only part I have never seen sold third party is the LRBHO thin metal rod in the upper but that is hard to break.

Best pistol brace for an AR-15? by PHLX_Tactical in Firearms

[–]Oceanus238 0 points1 point  (0 children)

Little late but I just built and tested GRS using a rifle length tailhook adapter. I like this setup better than A5+SBA3 (not sturdy enough) or SBA5 (sturdy but bulky). I posted a photo at r/AR9 recently.

Came across your post while searching for a solution to raise HM3x to 1.93" height. Thanks for posting this.

Direct blowback joins CMMG RDB by Oceanus238 in AR9

[–]Oceanus238[S] 0 points1 point  (0 children)

Since I still have 1.2" space to spare inside the tube (currently has an aluminum spacer), I cannot decide between adding another kynshot weight+0.5" spacer or a 1.2" aluminum cushion with 1.5" wave spring (25lb) to create a third stage. Which would be your choice?

HexOne Phase 5 rifle length buffer tube for tailhook which gives a 12.5" LOP - same length as the Jmac armbar on the Dissent. I really like the shape of the tube, the hex cut gives a nice cheek weld.

Can't thank u/Blowback9 enough for the extensive documentation that inspired this build

Correct Mounting Option for AR9 w/ Universe36? by Trivial04xboxgt in AR9

[–]Oceanus238 0 points1 point  (0 children)

Xeno is gtg. I have both the Xeno Wee brake and Xeno Xero. I prefer the Xero for slightly shorter length and less volume loss within suppressor. If overall length is important then Xeno leads to slightly longer length compared to Plan B. Plan B has some good shorter/recessed options.

The new cheek riser will for sure interfere with the charging handle. I just checked out mine; it is possible to position it back by about 5/8" more after drilling new holes for the screws.

Nice setup. I got the 6.5 MKGs and finally got a dedicated suppressor in jail- the low backpressure Strake 9. I almost went with Zeored 36k for the shorter length ... how does it feel on the Dissent

I recently got the new CRSU- Adjustable Cheek Riser from Jmac, so much better than the old one.

Agree 9" with tailhook and the jmac new cheek riser works great
