tnorman Posted January 23, 2015 Share Posted January 23, 2015 I just about have my first build finished. I have a seekins adj gas block,voodoo lw bcg and rifle length buffer and spring. Will this work or should I buy a lighter weight buffer and spring? Link to comment Share on other sites More sharing options...
Thehotrodpig Posted January 23, 2015 Share Posted January 23, 2015 With my jp low mass bcg I had to remove weight from my buffer. Ended up replacing the weights with a chunk of fuel line. 3oz seemed to be a final good weight which I think just happens to be right around the same weight as jp's buffer. I just ordered taccoms adjustable ultra light buffer yesterday. I hear good things about it and it's cheap. No matter what I believe you will at min be playing with your buffer weight. There are several ways to get the job done though. Link to comment Share on other sites More sharing options...
TyinTX Posted January 23, 2015 Share Posted January 23, 2015 I haven't bought a low mass bcg yet but I'm looking at getting the voodoo when I do. I did replace 4 steel weights from my rifle buffer and drop the weight to 2.9 oz with some delrin rod. Cost about $2. It did let me use less gas. Recently switched it for the Taccom ULW buffer. Don't have many rounds through it yet but so far I like the results. For the price it is worth a look. Link to comment Share on other sites More sharing options...
tnorman Posted January 23, 2015 Author Share Posted January 23, 2015 Thx. The weight in there now is 5.6 oz. Once I purchase the barrel and hand guard I'll put some rounds through it and go from there. Link to comment Share on other sites More sharing options...
MickB Posted January 23, 2015 Share Posted January 23, 2015 3oz is also the weight of a standard carbine buffer... Mick Link to comment Share on other sites More sharing options...
TonytheTiger Posted January 24, 2015 Share Posted January 24, 2015 Damn I thought I was the only guy running a super special rubber fuel line buffer system. It did take some of the twang noise out vs. an empty buffer too. Link to comment Share on other sites More sharing options...
tnorman Posted February 12, 2015 Author Share Posted February 12, 2015 http://www.cheaperthandirt.com/product/2-DPBS-11 This is the one I have currently. I can feel weights in it..to remove the weights I need to knock out the roll pin at the bottom to remove the rubber end cap correct? Link to comment Share on other sites More sharing options...
wgj3 Posted February 12, 2015 Share Posted February 12, 2015 That is the correct method for accessing the buffer weights. Link to comment Share on other sites More sharing options...

Finding some way to keep it steady while knocking the pin out is the hardest part. Link to comment Share on other sites More sharing options...
tnorman Posted February 14, 2015 Author Share Posted February 14, 2015 After putting 100 or so rounds through the new rifle I have noticed the recoil against my shoulder a bit. Would a heavier or lighter buffer lighting this? Link to comment Share on other sites More sharing options...
JoshF Posted February 16, 2015 Share Posted February 16, 2015 Buffer doesn't necessarily contribute to felt recoil as much as it speeds the cyclic rate up. It can be counter productive to where the recoil impulse is "sharp". The adjustable gas block will do far more to reduce what you feel in the shoulder. Tune it to just lock back on an empty mag with your load and then open the system like 1/4 turn more for insurance. Then you know you're dealing with just the cyclic weight. Now watch the reticle movement with multiple shots. Is it a slow bobbing of the reticle and brass coming out at the 5 o clock? If so a lighter buffer will speed things up and reduce the bobbing. If the brass is kicking out at the 2-3 o'clock position that typically means the bolt is cycling too fast which means all kinds of other issues. Hope this helps...

tnorman Posted February 16, 2015 Author Share Posted February 16, 2015 Thanks...I appreciate it. The brass typically lands between four and five. I'll check out the bob next time I go shoot. Link to comment Share on other sites More sharing options...
Bader3245 Posted July 15, 2015 Share Posted July 15, 2015 (edited) Today went out with my new set-up for the first time. I feel like the ejection is 4:30-5:00 as the shell casings were getting dented.Nordic 18" - Rifle Gas SJC Titan Comp JP Adjustable Gas - Adjusted to allow bolt to Lock Whiskey Arms LBC AL Carrier JP Enhanced Bolt Stock Rifle Buffer Spring Empty Rifle Buffer.My next step in my head was to go with a Reduced power spring (TTi) and bring the gas down further to slow the carrier down and still allow for lock-up but I also though adding weights back into the buffer would maybe again slow down the carrier and bring the ejection further up. Am I thinking about this backwards? It strips a full 40rnd P-Mag with TTi base (45), with authority, so i feel there is some room to go down on the spring. Thoughts? -S.Bader Edited July 16, 2015 by Bader3245 Link to comment Share on other sites More sharing options...
TonytheTiger Posted July 15, 2015 Share Posted July 15, 2015 No useful thoughts for you but if your the S. Bader that just registered for the Winnequah match next Sunday I can bring a TTI spring for you to mess with if you like. Link to comment Share on other sites More sharing options...
ihocky2 Posted July 15, 2015 Share Posted July 15, 2015 I have the Whiskey Arms LBC and run an empty rifle buffer that comes in just over 2oz. and a JP 25% reduced buffer spring. 18" intermediate gas barrel with the gas tuned and a Lancer compensator and the reticle doesn't move. I may need to go back and add a hair bit of weight to the buffer or step up to full power buffer spring to slow the cyclic rate. I love how the gun runs, but a few mags don't feed fast enough. My Pmag 40 and my Pmag and Lancer 30's run fine, but my GI 30's and my Pmag 20 don't always feed. My guess is that it is cycling too fast for them.

TonytheTiger Posted July 20, 2015 Share Posted July 20, 2015 Hey Bader3245, I forgot all about messing with the spring yesterday. I had an abysmal match and was in such a bad mood I spaced it out completely. .. Link to comment Share on other sites More sharing options...
72stick Posted July 22, 2015 Share Posted July 22, 2015 If your brass is dented with a low mass BC, your gun is over gassed and the extractor is loosing control of your brass with the higher cyclic rate. The dent occurs as the bolt returns & kicks the brass forward striking the ejection port and then flips it out of the gun. JP has a great Gas Gun video that explains this really well. The fix is to close the gas down till it doesn't lock the bolt back on last round and then start opening it up 1/4 turn at a time till it locks back. Give it another 1/4 turn open and it should be fine with most factory loads & stop denting the brass. If it still dents the brass, you can fine tune it more with a lighter buffer and go through the gas adjustment again. Less gas with a LMBCG and lighter buffer, adjusted for the correct cyclic rate, should stop denting the brass and give you a smooth running gun with virtually no recoil impulse.

Bader3245 Posted July 22, 2015 Share Posted July 22, 2015 Hey Bader3245, I forgot all about messing with the spring yesterday. I had an abysmal match and was in such a bad mood I spaced it out completely. .. HA, You and me both. I was actually running real well until an embarrassing mistake ended my day a little too soon. I actually have a TTi Spring arriving tomorrow that I will take to the range on Friday. I appreciate you seeking me out and bringing it with you. Rifle ran REALLY well though its first 4 rounds ever, should be interesting to see how much more gas I can pull out with the TTi spring. Link to comment Share on other sites More sharing options...
