Larue Tranquilo and OSS HX-QD suppressors

[Bob Mckenzie]

Hey folks doing an AR 10 6.5 creedmoor build and am looking for current updated info and experiences on the Larue and new OSS suppressors

Not a lot of info out there on these, other recommendations are welcome!

Thanks!

I have the OSS suppressors here, they are quite nice and I am looking forward to reviewing them.

To me, all the Larue stuff is hype, and never works as advertised. There were posts today about bad Larue results in the semi auto,

But I will be moving forward with 3 different OSS models and at first blush they are solid. The most important part will be the accuracy testing.

I have Surfires and Tranquilos. I run a Surefire SOCOM 7.62RC on my 260 bolt gun and the TQs on my 7.62 tOBR, 6.5 tOBR and .260 tOBR. I can't compare them to an OSS, but I can answer questions.

Thanks! I was hoping you’d do a review eventually, I’ve heard mixed results on the OSS long term function.

Just looking for that overall best can for an LR gas gun... any additional guidance is appreciated!

How has your experience been with the TQ’s? Repeatability, dB, chamber gas and such?

How has your experience been with the TQ’s? Repeatability, dB, chamber gas and such?

My experience with my two TQs has been positive.

I'd start by asking what type of shooting are you going to do? I only do square range stuff at Quantico out to 1,000, no running around, barricades, etc. It could make a difference if you want a quick attach system.

The TQ uses the LaRue brake and is screwed onto the brake. It has a double shoulder design along with a lock ring. Obviously, since it's made by LaRue, it has been tuned to the tOBR (or vice versa). As you may know, the tOBR has a dual gas block design with two differing sized gas ports, one for suppressed (smaller) and one for un-suppressed (larger). In my tOBRs, it's run flawlessly with almost negligible blow back.

My TQ does shift POI by 1/2MOA lower, but it's repeatable. I dial in an extra 1/2MOA and I'm good at any distance. It's also consistent, when I remove and reinstall the TQ, it's always 1/2 MOA. I get about an additional 25fps when using the TQ and it actually tightens my groups by a 1/4MOA.

I can't speak to db as I think they are all pretty close, but the TQ has a nice tone to it. Here's a short video attempting to compare the Surefire on my 260 to the TQ on my 260 gasser.

I've shot the TQ for about 1,000rds with no issues, as I have with my Surefire. I got my TQs for killer pricing, $499 and for the money, I think it's a good can for what I use it for. Hope this helps and ask questions if you need to.

I’m pretty new to the LR game, and I’m working on my first AR build: Aero M5E1 kit, JP LMOS bcg /Fire control/ Captured buffer, Rainier 6.5 creedmoor 22” ultramatch 1:8 with a superlative adjustable gas block. (Still waiting on a few pieces to arrive)
My local club has a 1000 yd silhouette range, and does a 1000 yd high power match’s, I’m thinking I will give PRS a try after I get some time and proficiency behind the rifle...

Awesome pics and info, I appreciate it!

I did a search for "Larue" and I'm not finding anything. Can you point me in the right direction? Not questioning you, just trying to learn.

Let me offer a gentle suggestion and my apology if you already know all this. While the AR15 platform is generally governed by the technical data package that allows the interchangeability of parts, all bets are off with a large frame AR. Do your research and read a lot about the 6.5CM and what people have discovered during their builds, they tend to need a bit more tweaking. I'm not familiar with all the parts you're using, but it's good to have the +2 on the gas system. The 6.5 has a lot of pressure left at the port that can really hammer a BCG. I'd be a bit concerned with the LMOS as (my opinion) you'd want additional mass to slow the cycle, especially when firing suppressed. Using the LMOS may then require a very heavy buffer to slow the cycle so the bolt isn't over-running the magazine spring and causing jams. Do the same research on rifle/suppressor combos as each suppressor has a different pressure level and blowback, which affects the rifle's operation. It could save you loads of headaches.

Good luck with the build.

I haven't tried an OSS suppressor yet but can say that the LaRue TranQuilo on an AR is the best suppressor I've used to date on a gas gun. Difference between suppressor on / off is minimal in terms of how hard BCG is cycled due to back pressure added from suppressor.
223, 25-08, 6.5 Grendel, 6.5 Creed, 260, 300 BO, 308 have all ran smoothly, trouble free with no adjustment needed to gas system between suppressed / unsuppressed. Accuracy with the TranQuilo has been excellent, does have a POI shift but almost every suppressor I've tried (bolt and gas gun) has that. Shift is consistent so is essentially a non issue, do the offset and then your DOPE is same same all the way out.

I might eventually test with an OSS suppressor but I'll tell you right now, TranQuilo is the suppressor to beat for a gas gun in terms of cost to performance ratio. Nothing against OSS, I do not have any first hand experience / data on those suppressors.

I'm not a fan of low mas BCGs in either the -15 or -10 platforms but if you can get the gas restricted enough it should work just fine. Powders used in 6.5mm calibers are going to have quite a bit higher port pressure and gas volume then a 308, which unlocks the bolt a little sooner than is ideal. Low mass BCG tends to make this more of a balancing on a beach ball scenario than I like. You've got an adjustable gas block and JP captured spring system (allows you to change weights) so you should have enough adjustment in gas system / BCG-buffer to tune operation of rifle to ammo once load is defined.

Thanks! It has a +2 on the barrel, the guys over at JP have been a tremendous help in this process, I can’t say enough good things about their customer service!
This is largely why I’m looking at the “flow through” design for my can

Have you had a chance to look at the repeatability and accuracy on the OSS cans as of late?

Would love to hear what has not worked for you with Larue products.

While I have read people having issues with them as well as most manufacturers , I've had great success with their 260 using their TQ suppressor.
