LWRC: For some reason LWRC seems to be one of the most polarizing brands of piston driven rifles the world over, and for the life of me I do not know why. LWRC makes a great rifle with state of the art components; they use a cold hammer forged barrel that is treated with some form of nitrocarburization (don't ask me the specifics I'm not a chemist), their bolt carrier groups are nickel boron or nickel teflon treated (both treatments work great but I can't keep straight what company does which treatment), and their lower receivers are fully ambidextrous. One of the other great aspects of LWRC is the multitude of options they have for caliber, size and length (they have everything from pdws to patrol and precision rifles). All that being said LWRC is not without their own cons one of which being that the company was bought by Colt. I'm sorry I couldn't help myself I just don't like colt as I have had to deal with their customer service on three occasions and all were bad (worked at a Gun Shop for a while). On a more serious note of all the piston rifles LWRC does seem to have the most breakable little parts, which is not to say their rifles are fragile, but rather that the people that buy them use them and their system seems to have more small parts. Small parts always break, and that is in every rifle across the board. One thing to credit LWRC is that they make in my opinion the most aesthetically pleasing rifle sold today. Much like Barrett they can be cost exclusive as these rifles tend to cost exclusively over $2000 across the country. I have heard mixed reviews of their customer service, but most of the negative accounts I've heard in person I would judge that the purchaser was kind of a dick. My final judgement is that these rifles are great buys, however if I bought one I would also purchase an extra couple piston parts kits.

have an overbuilt rifle that will likely outlast them in a combat situation.

Slingblade, I enjoyed reading your post they were well thought out and logical. I do however hope that PWS will enter the 6.8SPC market. I will likely buy an LWRC sometime in the near future but would love to have one by PWS. I have one 6.8 AR15 now by a different manufacturer and appreciate it for it's increase in terminal(knock down) power while still giving me the option of a 30 round magazine if wanted or needed. I doubt PWS will offer it but I would definitely consider it if offered.

Barrett Firearms: The rec7 is by all accounts a fantastic rifle, however their are very few options in regards to length and caliber. On the positive side many have said that their piston system is far and away the most robots of all that are available. I have seen on multiple occasions shooters put obscene amounts of rounds (over 1500) through these rifles in a day and these rifle do not even hiccup. All that being said these rifles can be very cost exclusive as the gen2 rifles are running in many cases over $2500, and I know many just can not justify spending that on a rifle when you can get top notch reliability for much less. There are a couple drawbacks to these rifle one being that it is hard to find one to put your hands on before you buy and the other being the very limited production of these rifles. The limited production affects a number of things, however none are more important than the difficulty to find replacement parts. To conclude any rifle that Barrett firearms makes is bound to be overbuilt to the nth degree and if one has the money or the justification to buy one then I believe they will be very pleased with the result.

....The only one of these I do not recommend is purchasing the Adams arms piston kit, however their complete uppers and rifles are wonderful....
