Im building my first ar, the lower is complete(a axts adacs ax556 billet lower, with a dpms single stage lpk, and RRA ambi safety, and magpul ubr stock) and i'm looking for a upper for it, i'm settled on get a adams arms 5.45x39 piston upper, but from my understanding piston systems work best when combined with anti tilt bolt carrier, and anti tilt buffer asesemblys, the question is if i have a anti tilt buffer assembly can this buffer still be use on DI systems without hamppering a DI function, i looking for the best adaptability for the lower, allowing quick swaps of teh upper and bcg for caliber change without having to mess with the lower.

So long as you purchase an agnostic buffer system i.e. designed w/pistons in mind but suitable for all ARs (as an example the PWS Enhanced Buffer System), yes, it can be swapped to a DI system upper without issue.

It will work if the DI bolt carrier hole is the same diameter or larger than the piston bolt carrier hole.

it terms of "agnostic" buffer, the only buffer i can find about pws enhanced buffer , their buffer looks like a normal buffer, not a anti tilt buffer, is it truly a agnostic buffer, able to work with both( or is it the whole system, meaning i also need their buffer tube, which isn't possible with a ubr stock, due to use of magpuls propreitary buffer extension tube

I am confused. You said you were interesting in purchasing an Adams upper. The Adams includes the piston specific BCG, but not the back end of the rifle (Buffer tube, buffer, and spring).
What you would then require are the back end components, and you stated (or I interpreted at least) that you were looking for a buffer tube that specifically addressed carrier tilt while  suitable for DI use without potential troubles. To my knowledge PWS is the only company that produces an agnostic  tube that was focused around elimination of carrier tilt but acceptable for use with any DI gun.

When I say agnostic, some piston upper manufacturers design proprietary systems through the addition of rails, pads, tongue and grooves, etc. on the carrier and receiver extension, and then design a buffer with various machined ends, and a tube with its own particular anti-tilt tricks.
As a complete system, it works and quite well. The problem is the various small tricks make mating the lower to a standard DI upper a potentially  dicey proposition. Too much system proprietary this and that married to upper that was not designed as part of the system could yield tolerance or functional problems.

why buy a $500 lower and put dpms and rra parts in it?

So i can get a FUNCTIONAL ar for cheap planking, while i await further and more expensive upgrades(in this case a alexander arm single stage, and a battlearms badass ambi safety) the lpk and safety was 70 bucks at a gun show thus i figured worth it to get it functional, the fine tuning with better parts will haappen later(and 600 lower not 500 lower rofl)

i have the UBR stock which comes with the receiver extension (buffer tube) what i still need, which would be seperate, is a buffer spring, and actual buffer, i wish to have a lower which by simply change the upper can be switched between different calibers and gas systems (know of course large caliber would require different buffer springsand such) without needing to change the buffer, thus i'm wonderign if i put a piston buffer for say a 5.45 piston upper for clean running, will it still work if i swap the upper for a di 5.56, i know normal buffers can be used in pistons but can cause problems, thus the question will piston anti tilt buffer work in di without causing problems.

dunno where you heard normal buffers causing problems in piston ar's, cause they don't.  Every piston manufacturer on the market right now uses standard buffers.

Buying an anti tilt buffer should not impede function on a di system.  All it is, is a nipple that's machined on the face of the buffer to fit inside the hole at the end of the carrier to prevent the carrier from tilting downwards.

The thing with ar's is you can't just have one system and expect it to do everything.   Sometimes buffer and buffer spring weights need to be changed out even when going di to another di upper shooting the same caliber. However your'e talking about going from a piston system shooting one caliber then going to a di system shooting a completely different caliber.  Even though the design of the anti tilt buffer might not impede function, the weights of the buffer and the spring could.

My advice is to just buy a standard buffer and not worry about carrier tilt.  Even if you do experience carrier tilt it will not be too much of a problem in the long run.

ok at808, guess i'll go with a normal buffer and work out the piton carrier tilt issue if it becomes appearent(i've heard nightmarish stories about it,wasn't sure how prevalent it actually is) and i know different buffer weights and spring strength will have a affect on on firing and my hope is most like unfeasable, but until i actually get mutlple caliber uppers its only a dream at this point.
