Thanks to all you guys using the DA series gas blocks.
Its been a ton of work getting them built to the quality we have now. There is much more to it than just drilling a hole and sticking a screw in there. LoL I have talked to many of you on the phone prior to the purchase and its always a pleasure meeting like minded people. Thanks again, Todd@SLR |

Good News-
.875" and .936" DA Series Gas Blocks are here. The will work with AR10 Pattern rifles and require the use of a straight gas tube. We made a relatively small run to gage interest but mostly because we wanted to help out the guys who asked for them. :) Getting Phosphate now. Will be up on the site next week. .936" Shown Proper Pics will come when they are plated. Pricing will be identical to the .625" and .750" DA series blocks at $95.99. Thank you! Todd@SLR

Just wanted to post with my experiences.
I had read that there were some issues with these fitting in the DD Lite series due to their ridiculously small opening at the rear of the rail.. But after talking with SLR I decided to give it a shot. Anyways, ordered set screw DA7 on Tuesday afternoon and got it today (Thursday) which is pretty awesome. But like some of the others it would not fit through the back of the DD Lite Rail. Knowing this might be the case I already had my Dremel out and ready to go. I ended up just using a sanding drum (#407) and placed it dead center in the bottom of the rail and let it radius off the two sharp corners of the rail that extend inward about an inch. This took all of 45 seconds and was all that was needed (removed maybe 1-2mm total). So if you are holding off on getting one of these cause you own a Lite Rail, don't be. In the picture below you can see the exposed metal where the sharp corners used to be. Also, thanks to everyone at SLR for the fast shipping and willingness to answer questions. 
tl;dr  : If you are worried about these fitting a DD Lite Rail don't be. It is minimal work to make it fit and I don't think it compromises the strength of the rail in any way.

Will this fit under a midwest ss gen2 slim rail? Thanks. It does fit. I put a setscrew version on a .750 barreled upper with a 12" M.I SSGEN2 rail with no problem ... except for having to trim down an accessory mount screw. By the way the block works as advertised. Good work SLR.. this is much easier to adjust than my Syrac block |

Just remember folks you can not use a non-metal (ex. Magpul) BU sight on a gas block - well actually you can - ONCE.

I grabbed this from Apex's site.. not sure if it's enough enough info for you
Inside Diameter: 1.750'': INSIDE CLEARANCE DIMENSIONS: .925'' above & .825'' below center of bore If these won't work, I'll be looking at the Precision Reflex tube or delta-style forearms... but they could have the same problem Precision just sent info about their round and delta guards The round hand guards are 1.9” ID to clear the end cap. The Delta you can install something that is 1.5” in diameter, straight up from bore center is 1.13” Reading the mechanical drawing you have in the previous post... looks like only the delta could work... tubes for the apex and Precision would not have enough room |

Yes the DA8&9 will require .308 HG's with a gas tube channel .
With our design we just can't make them any shorter. Thanks for doing the research though. We will have our own .308 HG soon. |

DA9-SSC and DA9-C for AR10/SR25 Pattern AR's Only.
Requires Straight Gas Tube and roomy HG's. We ran a limited number of these as demand is pretty low for the oversize blocks but some of you were persistent! 
DA8-SSC (DA8-C Photo shortly) 
 
DA7 next to DA9. LoL

Here is my quick test and setup of the DA7 NiB Clamp gas block on my AR-15. I love it!! Have it setup with a 1oz Spikes Buffer and Spikes NiB BCG, also RRA rifle length gas block.
Note: Of course, you have to adjust the gas block close to the business end of the gun. Take 1 of my vid explained the be cautious when adjusting. I was low on battery on this take and forgot to mention that. No rounds in mag when adjusting, single loaded rounds. I admit, I should have put it on safety but was low on time. Will work on it.

Hi. I am building a .338 Spectre upper and I like the look of the DA7 Clamp On. However, my barrel has carbine gas and my hand guard is a 15" long FF, so I think I will need an adjustment tool at least 9" long. Is your tool that long or can you suggest some place I might find one long enough? Thanks.

I shot my 300 build today with the slr adjustable gas block and got it just right where the brass lay in a pile and was cool upon extraction. I recommend this to anyone building a custom upper to make the right amount of gas to work for you. I want to get more in the future and my dad asked why my brass was so cool and his was so hot and his bolt was so much dirtier than mine. Thanks for a good product and customer service when I called them up to talk about it.

Yes! We are getting ready to unveil and whole new Adjustable gas block system unlike any thing out there and part of that is a toolless adjuster. This will also be offered for all of our DA Series gas blocks by the end of the year. Our new design will fit under every HG out there and take care of the issue of car gas and long rails. No long wrenches anymore and even better performance! Stay tuned! |

I've been researching every aspect of the new rifle I'm building and an adjustable .625 gas block for is a must. Something that is durable, user serviceable/cleanable, and fits under the slimmest of rails just make my choice that much easier! I have yet to read a negative review about your gas blocks. Thankfully I'm in no rush so I'll be anxiously waiting for your new version.

If we can find someone who can keep a tolerance in the future we might try again. The gains really don't amount to much other than the change in color . Heat treat and phosphate work perfectly. We run these by the thousands and we have it dialed. The 7R's are coming. They are tricky to do with the deep bore Updates coming Thanks Todd |

UPDATE:
A while ago got mine (set screw .625" size) installed and pinned in place by ADCO. It came back PERFECT. Just to show the versatility of this product, see what I am running: 10.3" DD LW barrel PWS muzzle break JP LMOS bolt carrier (lighter weight carrier) Buffer weight w ONLY a single steel weight inside + polymer spacers MI SSG2 rail (gas block fits under it perfect) Due to the low reciprocating mass, I turned down the gas setting. Tested 100rds today, 100% reliable in that chosen gas setting. VERY low recoil thanks to the MB, lower gassing and low mass. Still this SBR is VERY light weight, like 4.5 lbs. Did I mentioned less fouling than ever? My project is done! Only cons (if you are picky): my block had some machining marks on the front face. Still this is park'zed over and not visible at all under the handguard rail. Does not affect performance in any way. |

My impatience got the best of me today... I put a DA9 on my pistol length SBR and realized there was an issue with the gas tube not lining up , then reread Todd's post about needing a straight gas tube with the DA9. Couldn't find one ANYWHERE that was pistol length so I straightened one out. Finally got it on the gun, test fire went great so I went to put it together and the Hand guard won't fit. I don't really have the money to buy one from SLR and it APPEARED to be just a slight clearance issue... so... off to the grinder I go. Took the top screw flush with the gas block (it stuck up just a little) and took some off the bottom edges of the gas block more or less. After several passes and test fits I realize it will never fit because my HG doesn't have the channel to fit over the gas tube. FML! So now guess what I am asking for Christmas. Todd to give us a great price break on a 7" SOLO HG. I am desperate need of finishing this build.
