Works OK, had some alignment problems
Got this to remove the ejector from an AR15 bolt. The forcing screw kept slipping off of the end of the ejector pin, especially on the JP Enhanced bolt. I was able to finagle it eventually. Not sure if maybe a hole was mis-aligned. I will try cutting down a spent cartridge case and putting it on the end of the forcing screw. Otherwise, it got the job done after some frustration.
Good Idea Gone Bad
I ordered this when I ordered the FailZero EXO coated AR-15 bolt & carrier as I wanted to verify the head space. The FailZero extractor retaining ping was staked on one side in the bolt body. Alas, the pin was not going to line up with the hole designed to allow the pin to be captured while driven from the bolt body.
Have a 1/2" - 20 tap and die on hand
The tool is relatively easy to use once you can use it. I had to chase the tool's threads with a 1/2" - 20 tap and die to remove some of the coating. This is completely unacceptable especially since other reviewers had the same complaint. I would have rated it 4 or 5 stars and recommend it to a friend if there was sufficient product quality control allowing the tool to work as advertised out of the box. At least I can more easily check the head space of AR-15 and AR-10-style rifles now.
I can't recommend this product
I bought this Ejector Removal Tool as an aid in the removal of my ejector pins in two of the calibers I own, however the design is sound and in good design...the Brownell's Ejector Removal Tool seems to be manufactured and then sent for coating. I do not believe there is any final inspection of this device or units like mine would not be sent out to customers. It is very clear the unit is not tested for assembly after the Anodize/Coating process. The hard anodizing on the internal threads and the handle forced me to chase all internal and external thread surfaces with a Tap and Die set. The Chasing of the threads removed the hard coating and allowed the unit to be assembled. (Something we as a consumer, should not have to worry about). Even the smaller ID thread that holds the bolt block on either the .308 or the 5.56 side needed to be chased on the 5.56 side to assemble it for use. (Unit came setup for the .308 caliber bolt) After the extra work on my side, the unit is functioning and worked on both calibers of bolts. I placed a small amount of Anti-Seize agent on the internal threads to aid in storage since the coating had to be removed. I gave this unit 2 stars only because it is basically a sound design and it did become functional only after the chasing of all the threads on the device. They really need to look at the existing units in stock and weed out the defective units. My thoughts on this tool when I located on this site was this device can save me some money compared to having 2 separate units for my rifles. (I should have not discredited the reviews I read about the Brownell's Ejector Removal tool from users with similar issues). I should have went with the YOUNG MFG - AR-15/M16 BOLT EJECTOR TOOL it would have cost me more money and had 2 tools for 1 job but it does not seem to be coated on the threads. I will not recommend this item to others.
Couldn't put together
When I received this tool I tried to put the tool together but the threads weren't correct. I returned it to the Brownells store for another and that one was still defective. One of the guntecs said he preferred a Sinclair product but couldn't find it in the catalog. If the threads would be cut correct I think this would be a good product for AR15 and lr308.
Disappointing for AR-15 Bolts
I was really disappointed in this tool. One problem is that the handle tip is too small to properly engage the extractor plunger for a 5.56 mm bolt face. Tool handle tip is 0.310 and the i.d. of a 5.56 mm bolt face is 0.380. As such, the tool tip just barely engages the edge of the extractor plunger. Because of this the plunger is not pushed straight back, but at an angle causing it to jam. The large bolt face adaptor is 0.4165 and is too large to fit a 5.56 mm bolt. Another problem arises when reassembling the bolt. Because the tool tip rotates while depressing the extractor plunger, it also rotates the plunger causing it to misalign with the retaining pin, making pin insertion impossible. I had to resort to the tried and true method of a gun vise and drift punch. I was hoping this tool would make things easy. Brownells could solve this problem by supplying another bolt face adaptor that is 0.380 in diameter.
Quality Control lack of...
Good idea...but lacks quality control. Unit does not seem to have any quality control performed or some would call Final inspections of the device after it is plated/Coated/Anodized. Unit will not screw together due to coatings on threads. Not recommended unless you by chance get a good one.
