Q: Howdy gents, Any plans to make this item for different diameter gas block? I've got a .875 barrel I would love to put this on. Thanks!

Asked by: Wade - 1/11/2022
A: Wade, the .625" sizes are next, then the .875" sizes will come shortly thereafter. We're working to have these available by early spring. Thanks for your interest in Riflespeed.

Q: Hi, What is the maximum gas tube hole size on a barrel that this gas system can accommodate? What do you recommend for a 8" 300blk set up for subsonic?

Asked by: Neil - 1/9/2022
A: Gas ports up to 0.115" are supported. With an 8" 300BO you'll want to run somewhere in the neighborhood of 0.105"-0.112" depending on several factors. With a Gas Control installed there's little downside to a larger port, though. Thanks for your interest in Riflespeed!

Q: Is this compatible with a full length RIS II rail or would it touch the rail?

Asked by: henry - 1/6/2022
A: Henry, verify using the dimensioned drawings of the Gas Control provided under the “Fitment” tab on the Gas Control product page, but it should be no problem. We’ve used handguards as small as 1.225” inside diameter. Thanks for your interest in Riflespeed.

Q: Hi, Will be running 300blk 8 or 9" barrel subsonic mostly thru a pistol length gastube with your gasblocks. Would I still be able to run supersonic as well or would that damage the gas block due to pistol length and too much pressure?

A: That will be fine. Thanks for your interest in Riflespeed.

Q: Good morning. I am doing a complete Aero precision 300 blackout build. I am using a 10.5" barrel and an Atlas R-One 9.3" handguard. What are your recommendations for gas block? And will be a pistol length gas system as well. Thank you in advance.

Asked by: Miles - 12/30/2021
A: With a 10.5" pistol-gas barrel you can run an RS7543 with an 8" handguard. To evaluate other configurations, hit the "Choose Your Gas Control" link at the top of the site. There you can enter the measurements of various combinations of components and see what works. Gas Control model numbers that fit will be displayed in green. Models that do not fit a given configuration will be shown in red. Thanks for your interest in Riflespeed!

Q: Any chance we can see custom lengths? I’m looking for a 3.9”-4” length. I have a Midwest industries 11.5 handguard with a 6.5 Grendel lilja barrel. It’s a 12.5 but Lilja measures the barrel extension as well so it’s more like a 12”. Really like your solution for adjusting gas with no tools, currently using superlative adjustable gas block, and I have to take my can off to adjust it, I had the gas too light the other night and I was hog hunting, it was a single shot :(

Asked by: Reid Averill - 12/29/2021
A: Custom lengths are not an option at the moment, unfortunately. It would be much less expensive to purchase a shorter handguard. The Cross Machine Tool HDM 10.5 and DRT 10.5 are excellent options that are reasonably priced and may work for you. Thanks for your interest in Riflespeed & let us know if we can answer any other questions.

Q: Would this item work with a criterion 12.5" .750 gas block under midwest industries 11.5 handguard (MI-CRM11.5)? If so, which model do I need to purchase here? Thanks, Vlad

Asked by: Vlad - 12/24/2021
A: An 11.5” handguard on a 12.5” barrel won’t give you as much exposure for your Control Knob as we’d like. You can do it, but adjustments will be more difficult. A 10.5”-11” handguard is ideal with a 12.5” carbine-gas barrel.

Asked by: Thomas Woelfel - 12/24/2021
A: The RS7543 will be a good fit with a mid-length gas system and up to a 13” handguard. We will gladly send it to them. Just put instructions in the comment box on your order. Thanks & merry Christmas!

Asked by: Emmanuel Vargas - 12/23/2021
A: If your rifle is a direct-gas gun with a 0.750” diameter gas journal then you can use a Gas Control. Be sure to enter the details of your rifle into the Configurator on the “Choose your Gas Control” page (link at top of website). Thanks & merry Christmas.

Q: I have an Aero build with a 10.5" criterion barrel, a 9" Atlas handguard, and a Griffin Armament taper mount muzzle device. I did the fitment guide and it shows none of the gas controls will work with this setup. Is that correct? Doesn't look to be a lot of room between the handguard and the muzzle device. I also have an ADM build with a 12.5" barrel and 10.75" handguard. The fitment guide says a RS7915 will work. Is that correct? Thanks! Just want to make sure before I make a purchase.

Asked by: Kevin McAdams - 12/2/2021
A: Kevin, the 9” handguard will cover most of the Gas Control, but it is doable. You can see what an 8” handguard looks like on the homepage of the website. There’s a pic of a 10.5” carbine with a BCM MCMR8 handguard between the picture of the FDE upper and the OD Green rifle on a bipod. That will give you a way to develop an idea of what your 9” setup will look like.

Q: What is the minimum hand guard id that will accommodate the gas control? Will the atlas S-one or R-one from aero precision work?

Asked by: Caleb - 11/28/2021
A: The Atlas S-One has a lowered center section that prevents use in some configurations. The Atlas R-One fits fine. We've used handguards with an inside diameter as small as 1.225" (Midwest Night Fighter) with success. Most slim handguards are around 1.3" inside which fits easily. Check the "Fitment" tab on the Gas Control Product page for a dimensioned drawing that can be used to verify handguard fit.

Q: Dear Madame/Sir, I would like to inquire if your adjustable gas block can be installed on CMMG Resolute MK47/Banshee MK47 with 16" and 10-1/2" barrels and used with existing handguards?

Asked by: Nico - 11/10/2021
A: Nico, the best way to determine fitment is to enter the measurements of your configuration into the interactive Configurator tool on the "Choose Your Gas Control" page. You'll get color-coded results showing which Gas Controls fit your firearm. In the event that no models are shown to be compatible, the most common issue is with handguard length. You can enter different values into the "Handguard Length" dropdown to see what would work. If that's the case for you please email [email protected] with your measurements and we'll make some suggestions. Thanks for your interest in Riflespeed!

Q: I have a BCM 11.5 barrel with a BCM 10 inch mcmr rail but it's 10.5 to the flare I'm sure you no what I am saying will your gas block work with this build? Thanks

Asked by: Bullet - 11/8/2021
A: The RS7533 Gas Control will work if your gas journal is 0.750” diameter. The length of the MCMR10 handguard won’t provide as much access to the Control Knob as we’d like you to have, but the Gas Control will definitely work. The MCMR9 provides more than enough access if you wish to change handguards in the future.

Q: i recently purchased a PSA GEN3 PA10 18" MID-LENGTH .308 WIN 1/10 STAINLESS STEEL 15" LIGHTWEIGHT M-LOK STR SSA-E RIFLE. Does your gas control work with their setup and which one do you recommend. Thanks, Eddie

Asked by: EddieF - 10/22/2021
A: Eddie, thanks for your question. While the Gas Control would work with your carbine, the 15” handguard would cover up the Control Knob completely. This would make it more difficult than we’d like to make adjustments. With a mid-length gas system the RS7543 works with up to a 13” handguard and the model RS7558 works with up to a 14” handguard.

Q: Will the RIFLESPEED Gas Control fit under a BCM MCMR handguard or any other low profile handguards? I used the configurator to find the correct knob. I just want to know if it will fit under a handguard that requires a low gas block.

Asked by: Nic - 10/21/2021
A: Yes, the MCMR works great with Riflespeed Gas Controls. The 10.5" upper shown on the Riflespeed.com homepage and in the product images of the Gas Control product page is wearing an MCMR8. That's a great option for 10.3" - 10.5" builds. Thanks for your interest in Riflespeed.

Q: Are you folks going to make an option that fits folks with mid length gas, 16" barrel and 15" handguards in the future? I'd really like to get one of these on my DDM4V7. ??

Asked by: Benjamin Knoerle - 10/21/2021
A: Benjamin, this a great question and one that comes up often. The issue with your configuration isn't the Gas Control, it's the length of our handguard. The 15" handguard covers so much of a 16" barrel that it is difficult to access the Control Knob. It CAN be done, but making adjustments will be more difficult than we'd like. A 14" handguard offers plenty of access to easily make adjustments. If you don't mind having the Control Knob nearly tucked under the 15" handguard then the model RS7558 is the solution. Thanks for your question.

A: You’ll see no point-of-impact shift between the Gas Control settings used for each configuration, but may see some shift in point-of-impact when adding or removing a suppressor, as is usually expected. You’ll need to confirm or re-zero your carbine after installing your Gas Control to insure that your point-of-aim and point-of-impact are aligned. Thanks for your interest in Riflespeed.
