survivalshop Posted July 29, 2017 Report Share Posted July 29, 2017 (edited) Got your attention , I have an old AR that I'm beginning to replace worn old parts & though I would share some this late seventies built AR 15 components that are showing their age after almost forty years of service . This Rifle is built mostly of Olympic Arms Components , some mil surplus , because they were not many building in those times , Olympic Arms was one of a few who had Receiver sets or Match Hand Guards , I have on this Rifle one of the first types that came out . The HG is the Barrel Nut , one piece all Aluminum & I even have an all Steel one , that is a bit heavy for use , but some day make a complete Upper out of . I'm changing out the Buffer system , new Buffer ( Rifle ) & its Spring , The Photo shows how the Buffer Spring on the left , has a slight bend , unlike the new one on the right . I see anything but a straight Spring , I replace it . These , as with all other Components are original from the build date , The FCG is G2S & I installed a Flat top TM Upper , to install a scope , she has had & only been shot with A2 sights from the beginning ,until I went with the FT of course . This photo shows is of the Buffer , notice its designed a little different & also notice the Discoloration of the Bumper at the end .

survivalshop Posted August 1, 2017 Author Report Share Posted August 1, 2017 The BCG disassembled show wear , its a Government contract Milspec M16 BCG , no idea how many rounds this has had through the years , I mostly use this rifle for testing , because of the 24" Match Barrel .

Rsquared Posted August 3, 2017 Report Share Posted August 3, 2017 At the very least, I'd say that you got your money's worth out of it SS. Quote Link to comment Share on other sites More sharing options...
bubbas4570 Posted August 3, 2017 Report Share Posted August 3, 2017 This is actually another testament to the longevity of the AR platform when it is done correctly. And I may assume that it still retains very good accuracy.... Quote Link to comment Share on other sites More sharing options...

Yes it does , Stainless Steel , Ultra Match , HB . 4 hours ago, bfoosh006 said: Impressive ! Did you ever change any parts ? And I assume you are reasonable when it comes to cleaning and lube ! Again .. impressive !! As far as needed parts , I think I replaced the Firing Pin many years ago . I installed a Flat top Receiver a few years ago , just to put a Scope on , to see how well she did shoot , Iron sights ( A2 ) work, but hard to tell what kind of precision can be attained with out a decent Scope ( at least for me ) . I installed a Geissele G2S for the same reason . other then that & what I just replaced are it . I'm taking a new Extractor , Spring , Pin & an Ejector ,Spring & pin, with me to the Range to see what is needed fix the short ejection issue that has cropped up . The replacing of the Buffer system may be all that is needed . Edited August 10, 2017 by survivalshop Quote Link to comment Share on other sites More sharing options...
bfoosh006 Posted August 11, 2017 Report Share Posted August 11, 2017 Again very impressive parts / rifle life. Taking care of your "tools" works ! Quote Link to comment Share on other sites More sharing options...
survivalshop Posted August 23, 2017 Author Report Share Posted August 23, 2017 (edited) Just an update on the Rifle after changing out to a new Buffer & Spring , all brass ejected at 3 o'clock & out about 3-4 ft. , much better then dropping hot out of the Chamber on my hand . So , that shows that the Extractor & Ejector are not the only things that can effect ejection .
