Geissele Automatics Reaction Rod for AR-15 Uppers
Ratings & Reviews
Heavy Duty; Excellent Quality
A bit pricey compared to the competition, but you get what you pay for when you purchase from Geissele. Buying twice, though, is false economy, so this tool gets it right the first time. Fast processing and shipping from PA, as is their norm.

a must have for a smooth ar build.Fast shipping :)
A "must have" for every AR armorer
Absolutely perfect tool for installation/removal of muzzle devices, handguards, barrel nuts, and more. Any time you need to securely hold your upper for maintenance, this tool does the job.
Also have the Magpul block, but this is hands down better in a couple of ways. First it slides into the upper receiver for more support. Secondly I like the fact that you can rotate the upper 360 to work on it. Lastly Primary Arms always gets all of my orders out quickly and is truly two day shipping.
excellent product, excellent service from PrimaryArm also.
Perfect tool for the job

Excellent tool for this type of job. Tool is a little pricey however
by Scott Reid
Expensive? Yes. Quality? Definitely!Much better option than using any other upper receiver type clamp. It fits snug, feels rock solid when attaching a barrel or compensator. Very happy with this purchase!

Great product and service from primaryarms
Haven't had a chance to build with it yet, but it's a solid looking tool and I have no doubt it will perform with the quality Geissele is known for.
Heavy and Solid
Haven't used it yet, but very heavy and solid.
A top of the line tool
by Bill A
I guess for the price of this piece I was expecting a lot . I was not disappointed. This is a finely crafted and finished tool. That should come in handy for years to come. It's a much better way to do barrel work and upper receiver work than with the prior clamp and poly insert I was using before. Can u do the work without it? Yes. Does this thing allow you to do it like a pro and with ease and less likelyhood of damaging your upper? A most definite yes. Good purchase.
Excellent Customer Service
by Joseph Onorato
I missed their labor day sale by one day but they provided me the sale price. Also, when I showed them that another company had free shipping they provided that also. Cant beat that! Thanks.

It won't fit into the barrel extension even after a scary amount of effort. I was afraid I'd ruin my barrel extension. I was very disappointed.
by Neil Laljie
It's a little shorter than expected but other than that it was just as described shipped and delivered very quickly will definitely order from them again

It's a solid piece of bar stock cut to engage the locking lugs of the barrel extention on an ar15. Works as advertised to take stress off of the aluminum frame and places it on the infinitely more solid barrel. When tightening barrel nuts and brakes.

Looks like it will be a great tool when I remove the flash suppressor on several rifles.

Perfect tool for quality work. Tried using barrel vise jaws to install muzzle brake but upper receiver wanted to keep on rotating when carefully torquing brake. Ordered this tool and completed work in less than 5 minutes. Customer service was also excellent which I used to inquire about order. Top notch service unmatched by competitors as far as I am concerned.
Geissele Reaction Rod
Primary Arms delivers! They were the only ones who had this in stock and not charging above msrp.

PRIMARY Arms had the best price and I received my Geissele rod quickly. With the increase in the number of manufactures making billet lowers it gets expensive buying different mounts for each one. The G rod works on all of them without worrying about scratching the finish or putting undue stress on, what can at times, be a very expensive lower. If you had a "unicorn" lower would you trust it to a cheap delron and pin mount?
by Daniel Stanton
Super easy to use. Excellent quality. Relieves any concerns about placing stress on an upper receiver when removing or installing a barrel nut.
Interesting new device
The Geissele Reaction Rod is built like a tank. So far all I've done with it is remove a muzzle device and barrel nut but it worked fine for that. However, if the device is not held vertically in the vice it will slip in the direction of the torque. Also the barrel will obviously slip off if the rod is angled downward.
The Reaction Rod is a good piece of kit for anyone who does more than basic maintenance on the AR platform.It allows assembly minimimizing stresses and allowing proper torquing. It is essential if assembling anything with an integrated rail such as the VLTOR VIS or Mega Monolithic.
The Reaction Rod is the most professional and sturdiest method available for working on anything on the upper. From barrel nuts and rails to muzzle devices on SBR's where there isn't any barrel to clamp, this is the only way to go.I fully expect this tool to outlive me. It's that well built.
