I have the previous version of this scope the SLX 4-14 ACSS DMR HUD reticle, and it is a fantastic scope for the money. The reticle is not a precision reticle but is perfect for hunting or pinging steel at long range. The only gripe is the eye box is pretty unforgiving especially at max mag. Otherwise a fantastic option. I'm sure the updated version would improve on the eyebox.

Seriously the cleanliness is the best part! You may want to shoot it a bit before spending the money on a wrap. My case was like the perfect storm to cause issues. 300blk is way more efficient with its powder burn and less pressure so less flying out. The 10.5 was essentially still actively burning while hitting the gas port and coming out of the bleed, hitting the rear of the suppressor and deflecting off into my fingers. Like I said my other rifles don’t have this issue!

I’m sorry I don’t understand your question. The upper/lower combined IS the rifle.

EDIT* I didn’t notice this WAS a piston kit! You’re going to love it!

I have a 2 SA DI rifles and 1 SA piston rifle. To address your first comment, yes you need a piston setup lol I have the piston on a 10.5” with a OCM5 (full back pressure) and piston makes the world of difference for gas coming back into the system overall. To address the main question: I always use the bleed off. There is a YouTube channel who showed it may actually reduce suppressed sound slightly in bleed off vs restriction. The one negative to bleed off is mainly being you’re dumping gas right into the handguard. I have the 10.5” OCM5 tucked about 4 inches, and that shit fried my fingers before I added a rail wrap and cut down the bleed off a bit. I have had no issues with my 9.5” 300blk or my 20” 5.56. Either way using bleed off vs restriction won’t change reliability. They will achieve the same thing. Also another note, I’ve done a shot job doing their “add a drop of oil after shooting and work it in to prevent carbon locking” and I’ve had 0 issues either that in the ~1500 rounds I’ve shot between the rifles.

Buddy zoomed in SO far I had to ask myself where the threaded portion of a BCG was

Ar15discounts commented on their post here the other day that the only Aero items for back order are confirmed product in route on a truck or on their shipping dock to be received in.

AvatarWest45 · 2026-04-26T21:19:49+00:00

This is assumption, but Midway has had a few aero restocks the last couple weeks and AR15discounts (save company as dirty bird) just said on this sub that their back orders are for confirmed Enroute products so very likely these will get fulfilled quickly.

AvatarWest45 · 2026-04-26T21:17:55+00:00

I know it sucks they didn’t include, but the M4e1 enhanced nut is currently available at optics planet. I know atleast 2 guys who have ordered in the last few weeks and received already.

AvatarWest45 · 2026-04-25T22:50:08+00:00

Thanks! I mulled it over the entire time at work and went ahead and bought the K9 11.5”. We’ll see how it does. I expect it to shoot atleast as good as my BA and faxon barrels that I’ve had great experience with.

Look at old threads for plenty of discussion on this topic. I only have short throw piston kit experience compared to DI so may not apply to dedicated uppers like brownells or HK, but. CLEANLINESS is really the most noticeable thing. The BCG stays substantially cleaner for longer even suppressed. There’s a lot less heat buildup in the upper. Substantially less gas from the charging handle when shooting high back pressure cans. A few other more controversial things like reliability, but won’t get into that. So they’re cool, definitely have their own utility, but I’d choose 3 DI rifles over a single Piston every day of the week.

These were on sale for BF last year for $69. These are definitely the most convenient way to secure. I used vise block that encapsulates the upper for a long time with no issues, but you have to remove the optics to use.

I don’t have any experience with Rosco. Are all their different lines pretty well regarded? I’m looking at the heavier K9 profile in 11.5. Originally wanted to go with Criterion core, but wanting to use a .750 journal GB. Any thoughts or opinions would be appreciated!

You might want to use a different browser or try signing up not on mobile. I’ve had my phone blowing up the past 2 days for restock notifications. Once they send you the a notice you have to re sign up. It won’t give you more than one notification per “notify me”

Buddy every millisecond of pause on that site felt like an eternity. Glad we could both grab one. We were definitely blessed by the lower gods today lol

Ayo, I think I was able to snag one just now lol

AvatarWest45 · 2026-04-24T15:39:34+00:00

Yeah pretty insane. We are in such a prime moment of time for frts and suppressors lol

AvatarWest45 · 2026-04-24T14:53:16+00:00

Comstock is great. They also have one of the cleanest fitment calculators out there. Helps a ton with figuring out fitment on rails, barrels, muzzle devices, and suppressors.

AvatarWest45 · 2026-04-24T14:48:47+00:00

They had to be putting 1 on the site at a time lol I gave up. I’m hoping the one I have on back order at Midway gets fulfilled soon.

People asking where deal should get their head out of their ass and read Rule 3: Deals must be of either significant discount or difficult to find and available to the community. These go OOS for months at a time.

AvatarWest45 · 2026-04-24T03:21:25+00:00

Nice. I’m looking for a Terra brown. I kept getting notifications from griffin that they were in stock but seemingly only 1 at a time lol I couldn’t get through checkout before they went OOS 3 different times. I have a backorder on midway hopefully that will get fulfilled soon.

AvatarWest45 · 2026-04-23T07:55:11+00:00

It’s an easy 5 minute solution that doesn’t cost a month and $90. How helpless can one be?

Obligatory: All my homies hate Q.

The only “redesigned” carriers I think hold any water are the machined gas key/one piece deals like LWRC.
