5 If budget matters more then color Posted by turbo1889 on 21st Sep 2019

I did a lot of research on these lowers before I ever purchased. The reviews from other buyers other then those found on this TAC online store we're actually more positive and better for this large frame LR-308 polymer receiver that TAC has created then their AR-15 polymer receiver. Several reviewers who had both were pretty clear that the large frame LR-308 holds up better (counterintuitive that the polymer lower for the larger more powerful cartridges would hold up better then the normal size AR-15 frame). Reviews were basically solid that the TAC large frame LR-308 will basically stand up to anything but the "push-up test". So I purchased a pair of these to start with and built a pair of guns up on them. (By the way TAC needs to add "Bear Creek Arsenal AR-10 Complete DPMS Gen-1 compatible" uppers and "Noreen Firearms DPMS Gen-1 High Rail Pattern Forged" stripped uppers to the list of uppers that work with these lowers. Noreen especially fits really well!). And I have been very pleased with the results. They are working great !!! As suggested an extended mag release button that is a taller button only and does not have a tab that makes the button larger, just taller is strongly suggested (PSA sells them for $4 each). Also, I preferred to use a true Armalite AR-10 pattern carbine buffer tube and spring (Luther arms $20 tube + $5 spring) rather then a standard AR-15 buffer tube so that I could use a standard three weight AR-15 standard buffer rather then the special DPMS two weight shorty buffer and special heavy spring. I used PSA Magpul MOE EPT AR-15 lower build kits to build up my lowers ($80-to-$120 depending on exact options and on-sale or not-on-sale) just substituted the Armalite AR-10 pattern tube and spring and the taller mag release button. Then put bulk purchased tungsten weights in the buffers as necessary. In addition, as an unexpected bonus, the mag-wells on these lowers are cut more generously internally and will accept the low cost poly ProMag 308 magazines ($13 for 30-round mags !!!) and allow them to drop free that most people using other 308 lowers complain are too fat and are too tight in their mag-wells and will not drop free. Long story short, so long as you don't try to do push-ups on your rifle, these will do the job and work well.
